Introduction

Once you have collected and reconciled the ED records, the next step is to extract and code the relevant surveillance data. There are 16 NEISS data variables. They are:

  • Treatment Date
  • Case Number
  • Age/Birthdate
  • Sex
  • Diagnosis
  • Body Part Affected
  • Disposition of Case
  • First Product Mentioned
  • Second Product Mentioned
  • Intent
  • Location of Incident
  • Fire Involvement
  • Whether Work-Related
  • Race and Ethnicity
  • Race Other and/or Ethnicity
  • Comments

 

Each data variable has a set of associated codes used to describe the specific circumstances of an ED case. Data variables also have associated coding rules to help you select the proper codes for each case.

Introduction - The Coding Sheet

The NEISS coding sheet gives you a convenient way to code surveillance data for each ED case prior to entering it into the NEISS computer. The coding sheet organizes and presents the surveillance data variables in the order in which they are entered into the NEISS computer. The coding sheet has space enough to code several cases.

Lesson Topics


Coding Treatment Date

Code the date on which the patient was seen for treatment. Treatment date is coded in the format MM/DD/YYYY with a zero added to days and months that are one digit numbers.

For example:

Date of Treatment
  Code

July 17, 2000
November 3, 2001
December 20, 2000
March 12, 2005

  07/17/2000
11/03/2001
12/20/2000
03/12/2005

Lesson Topics


Coding Case Number

Each case treated on a specific date must have a unique number of up to 8 digits.

  • If your hospital uses more than eight digits for its case numbers, code only the last eight digits.
  • Do not code any letters of the alphabet which may appear in your hospital's case number. Instead, substitute zeros for any letters.

    For example:

ED Case # NEISS Case # Reason
9553432166
123 ED 456
12345
53432166
12300456
12345
Last eight digits only.
Replace letters with zero.
Less than 8 digits is acceptable.

 

Lesson Topics


Coding Age

PC-NEISS will automatically calculate and insert the age of a patient if you enter the date of birth. If the date of birth is not available, the age of the patient must be entered.

  • For a patient two years of age or older, record age in years.
Example:

45 years old
7 years old
Not recorded
= 45
= 7
= 0

 

  • For a patient under two years of age, code the age in months and put a “2” in the first block of the age field.
Example:

12 months old
22 months old
1 month old

= 212
= 222
= 201

Lesson Topics


Coding Diagnosis

The two (2) digit diagnosis codes are listed in Appendix B and D of the NEISS Coding Manual located in the course Tool Kit. For coding purposes, always use the most specific diagnosis/diagnostic information provided by medical personnel. If specific information is not available, review the patient’s complaint and the treatment given to arrive at the most logical diagnosis.

Other considerations for coding diagnosis are:

  • When more than one diagnosis appears on the emergency department record, code the one that seems to be the most severe and note the other diagnoses in the “Comment” field.
  • If diagnosis code 71 (Other/Not stated) is entered, the cursor automatically tabs to the “Diagnosis Other” text field. You are required to enter a text string in this field to describe the “other” diagnosis.
  • If diagnosis states R/O (Rule out), code this as the diagnosis only if there is no other specific diagnosis to code.
  • If there is a poisoning or chemical burn to a child under 5 years old from a product which is not listed in the coding manual, or if the product code is underlined, use code 5555.

Coding Diagnosis - Burns

There are several types of burns and associated codes. If the attending physician's diagnosis is inadequate, one can sometimes deduce the type of burn from the kind of incident and product(s) involved.

Code Burn Description
46
47
48
49
51
73
Electrical
Not Specified
Scald
Chemical
Thermal*
Radiation
contact with electrical current
all other burns
contact with liquid or steam
contact with caustics, acids, or alkalies
contact with flames or hot surfaces
cell damage by ultraviolet, x-ray, microwave, laser, etc.

* For thermal burns, indicate in the “Comment” field if the burn came from flame or hot surface.

 

Example

Lesson Topics


Coding Diagnosis - Poisoning

Code 68 (Poisoning) should be used when a patient:

  • Swallowed either a liquid or soluble chemical or drug/medication.
  • Inhaled vapors, fumes or gases; e.g.., from chemicals, cleaners or fuels.
  • Exception: For inhaled vapors from carbon monoxide (CO) and smoke
    from fires use code 65 (Anoxia).

  • Swallowed either a liquid or soluble chemical or drug and had an “allergic reaction”; e.g.., including swelling, skin rashes, etc.

When diagnosis code 68 (Poisoning) is used, always use body part code 85 (All parts of body).

 

Example

Lesson Topics


Coding Diagnosis - Anoxia

Code 65 (Anoxia) should be used when the patient cannot obtain sufficient oxygen, either due to hampered breathing or lack of oxygen itself.

Code anoxia when:

  • The diagnosis is strangulation, suffocation or asphyxia.
  • The patient has inhaled products of combustion, such as carbon monoxide (CO), smoke, soot, etc. (e.g., from a house fire, heating appliance, or camping equipment).

When you use diagnosis code 65 (Anoxia), you should also used the body part code 85 (All parts of body).

 

Lesson Topics


Coding Diagnosis - Ingested Foreign Object

Code 41 (Ingested foreign object) must only be used when both of the following conditions are met:

  • The patient has swallowed an insoluble, solid object; i.e., an item that will not dissolve in liquid.
  • The swallowed object is not likely to cause poisoning.

When you use diagnosis code 41 (Ingested foreign object), you should also use the body part code 00 (Internal).

Some commonly swallowed objects are coins, toy parts, buttons, nails, crayons. The foreign object may or may not have lodged somewhere inside the body.

 

Lesson Topics


Coding Diagnosis - Aspirated Foreign Objects

Code 42 (Aspirated foreign object) should be used when an object causes choking or is caught in the nose, lungs, or airway in between the nose and the lungs, and should generally be one that does not lead to poisoning or anoxia (inability to obtain oxygen). Examples of such objects are thumbtacks, beads, miniature light bulbs, and even pills.

If the victim chokes while being fed liquids and the hospital record describes the event as an aspiration, then the aspiration code may be used.

When you use diagnosis code 42 (Aspirated foreign object), you should also use body part code 00 (Internal).

 

Lesson Topics


Coding Diagnosis - Other / Not Stated

Code 71 (Other/not stated) is used if none of the listed diagnoses in the NEISS Coding Manual are appropriate. Whenever you use diagnosis code 71 (Other/not stated), the PC-NEISS software requires that the actual diagnosis, if stated in the ED record, be noted in the “Diagnosis Other” text field. If the diagnosis is not stated, enter “unknown” in the “Diagnosis Other” text field.

 

Lesson Topics


Coding Body Parts

The two (2) digit body part code is used to locate an injury on the patient’s body. See the NEISS Coding Manual, Appendix C in the course Tool Kit for a list of the body part codes. The body part diagram in Appendix D will also help you visualize more clearly the boundaries between body parts.

In general, if an injury affects more than one body part, code the body part that seems to be most seriously hurt. Then, mention other affected body parts in the “Comment” text field.

Occassionally, a report will say "Lacerations to the right side," where many body parts are involved but none is specifically mentioned. In such a case, you may use body part code 84 (25-50% of body) or body part code 85 (All parts of body); i.e., more than 50% of the body.

Use body part code 84 (25%-50% of body) when a burn injury scenario specifically states that 25-50% of the body was burned, or when the record states that multiple body parts are involved but does not identify any specific body part.

 

NEISS Tip button

Lesson Topics


Coding Body Parts - Special Injuries

Back Injuries

For a diagnosed back injury, determine if the upper trunk, lower trunk, or cervical vertebrae was/were involved:

  • Use the waist or navel as the dividing line to differentiate between upper and lower trunk.
  • Use code 31 (Upper trunk/Thoracic vertebrae) for upper back involvement.
  • Use code 79 (Lower trunk/Lumbar vertebrae) for lower back involvement.
  • Use code 89 (Neck) for cervical vertebrae involvement.


Burn Injuries

  • If only one body part was injured, code that body part. If more than one body part was injured, generally code the body part with the most severe injury.
  • For burns involving up to 25% of the body, code the most severely burned body part.
  • For burns covering 25% to 50% of the body, use code 84.
  • For burns covering more than 50% of the body surface, use code 85.


Eye Injuries

  • For injuries to eyelids, eyebrows, or the area immediately around the eyes, use code 76 (Face).
  • For an injury to the eye itself, use code 77 (Eyeball).


Head Injuries

  • When coding head injuries, code the most specific diagnosis given.
  • Code 62 (Internal organ) when there is no specific diagnosis for a head injury.
  • Coding the most specific diagnosis should not take precedence over coding the most severe injury. For example, for internal head injuries such as subdural hematoma, hemorrhaging, etc., use code 62 (Internal organ).
  • Code 58 (Hematoma) if the diagnosis only states “hematoma to the head.”
  • When there are two injuries even to the head, code the most severe.

 

Lesson Topics


Coding Disposition

Use the codes listed below to indicate the disposition of a case:

Code Disposition
1
Treated and released, or examined and released without treatment.
2
Treated and transferred to another hospital.
4
Treated and admitted for hospitalization (within the same facility).
5
Held for observation.
6
Left without being seen.
8
Fatality, including DOA, died in the ED.
9
Not recorded.

 

 

Lesson Topics


Coding Products

There are two coding fields for products, “First Product” and “Second Product.” Use these fields to code the consumer product(s) associated with an illness or injury. All product codes are listed alphabetically in the NEISS Coding Manual in the course Tool Kit.

Here are some general guidelines to follow when coding products:

  • When only one product is associated with an injury, enter the code for that product in the “First Product” field and fill in the “Second Product” field with four zeros (0000).
  • Whenever possible, report specific products rather than general types of products. For example, code hand saw and gas oven vs. saw and oven.
  • Use the “other” product codes, as in “Other baby carriers,” only when the ED record identifies a specific product but there is no code given for that particular product.

Consult the NEISS Coding Manual for a detailed discussion of product coding.

 

NEISS Tip button

Lesson Topics


Coding Products - Two Product Injuries

When two products are associated with an injury, either product may be coded as the first product and the other as the second product.

Example: An 11-year old boy riding a bicycle ran into a swing

Product 1 = code 5040 (Bicycle) and Product 2 = code 3246 (Swings) or

Product 1 = code 3246 (Swings) and Product 2 = code 5040 (Bicycle)

Exception:

When two products involved in an incident are the same product, do not code a second product; simply fill in the “Second Product” field with zeros. For example, if two skateboard riders collide, code 1333 (Skateboard) for “First Product” and code 0000 for “Second Product.”

 

NEISS Tip button

Lesson Topics


Coding Products - Code 7878

Code 7878 is used if a product is unknown, not mentioned, is not a consumer product; e.g.., sidewalk or driveway, or you cannot find an appropriate code. Code 7878 may only be used as a firstproduct code and is always followed by code 0000 in the second product position.

Do not use code 7878 if a case also mentions a second product that is a codeable product. Code only the codeable product.

 

Lesson Topics


Coding Products - Code 9999

Code 9999 is used if:

  • You believe a case involves a consumer product, but you cannot determine an appropriate product code.
  • You have a coding question about any case and are not able to discuss the case with your NEISS representative.

Headquarters staff will review these cases and determine whether a current NEISS product code can be used, or if a new product code should be added to the coding manual. In either case, your NEISS representative will contact you after reviewing the case.

 

Lesson Topics


Coding Products - Special Incidents

Flammable Fabric

If a burn or smoke inhalation injury results directly from a flammable fabric, use the product codes for the source of the fire (e.g.., stove, portable room heater, camping lantern, etc.) and the first item to ignite (e.g.., blanket, clothing, draperies, slipcover, etc.).

In addition, you must enter the appropriate code 1, 2, or 3 in the “Fire” coding field to indicate that the incident involved smoke inhalation, unexpected flames or smoke, or unexpected spread of flames or smoke. (See the section on coding fire.)

 

House Fire

Code 1866 (General home or room involvement in fire) is used as the “First Product” code in the case of a house fire and/or smoke inhalation where no specific product is identified. For example; use code 1866 when the emergency department record describes the incident as "house fire" or "fire in the basement" and no other information is available.

  • If a specific consumer product is identified, code only the specific consumer product.
  • If a fire involves an out of scope product (denoted by an underlined product code in the coding manual) or a drug/medication, use both code 1866 and the out of scope product code.

Also, whenever code 1866 is used:

  • State the particular room involved, if known, in the “Comment” text field.
  • Enter the appropriate code 1, 2, or 3 in the “Fire” coding field to indicate that the incident involved smoke inhalation, unexpected flames or smoke, or unexpected spread of flames or smoke. (See the section on coding fire.)

 

Product Fire

  • Code the specific product(s) involved in a product fire. A product fire can be extensive; e.g., fire/flames or limited; e.g., with smoldering/smoke.
  • Enter appropriate code 1, 2 or 3 in the “Fire” coding field to indicate that the incident involved smoke inhalation, unexpected flames or smoke, or unexpected spread of flames or smoke. (See the section on coding fire.)

 

Hot Water

Code 1934 (Hot water) is used for hot water injuries.

  • When an injury involves hot water, code the source of the water (e.g.. tea kettle, sink, bathtub, etc.) as one product and use code 1934 (Hot water) as the other product code.
  • If the source of the hot water is unknown, use code 1934 (Hot water) as the product.

 

Lesson Topics


Coding Intent

Use the codes in the table below to indicate whether an injury resulted from a confirmed or suspected intentional act. An intentional injury or poisoning is one that is inflicted with the aim of injuring or killing. The injury may be either one that was inflicted by one person on another or one that was self-inflicted.

Code   Description
1
  Assault/intentional injury inflicted by one person on another person.
2
  Self-inflicted injury (confirmed or suspected).
3
  Injury related to legal intervention due to law enforcement activities.
0
 

Unintentional (accidental) injury or intent not known or recorded.

 

Lesson Topics


Coding Intent - Assault / Intentional Injury

Code 1 (Assault/Intentional injury) includes all confirmed or suspected cases of injuries and poisonings inflicted by one person on another person regardless of:

  • The age of the victim.
  • Involvement of a product.
  • Occurrence on the job.


This rule includes intended and unintended victims of violent acts. Also included are injuries resulting from civil disorders and other conflict situations; e.g.., riots, strikes, terrorist activities, etc.

Q: How do we code injuries associated with store displays or signs?
A: Report injuries associated with store displays or store signs using the product code for public use items
(1738).

Q: How do we code the product in a case which indicates "victim fell off standard adult bed"?
A: Use product code 4076 for "Beds or bedframes, other or not specified". This code covers regular adult beds as well as beds, not specified.

Q: How should we code cases where the record indicates the patient was walking or running and sustained an injury if no other activity or product is mentioned?
A: Report all walking or running injuries. When there is some indication that the walking or running was an exercise
activity, use product code 3299. Otherwise, use product code 7878.

Q: How should we code cases where the victim was hunting at the time of the injury?
A: Report hunting injuries using product code 7878.

Q: How should we code combination products such as crib/playpens and combination sofa/recliner chair?
A: If the coding manual has no code for the combination product, code it according to the description of usage at the time of the injury. For example, “Pt got hand caught in recliner portion of sofa” should be coded as recliner chair (0670).

Q: How should I code a case where a product mentioned in the scenario is not present at the time of the incident? For example; victim stepped on rusty nail – was not wearing shoes.
A: Do not code non-existent products or activities, but be sure to mention such products in the narrative.

Q: How should we code logs (for example, jogging down a path and tripping over a log, or burned throwing a log onto a bonfire)?
A: Wooden logs should be coded as 7878. They are not considered fireplace equipment. Non-wood logs that are sold specifically to be burned in a fireplace should be coded as fireplace equipment (0663).

Q: How should we code cases where the diagnosis states “substance abuse”?
A: In cases where only “substance abuse” is stated, use product code 1929 for drugs or medications not specified. If substance abuse is mentioned and the record specifically states either drug use or alcohol involvement, then the drugs or the alcohol should be coded (1929 or 1903). Do not use both codes unless both alcohol and drugs are specifically mentioned.

Q: How should we code poles?
A: In general, code poles as 1865. When scenario involves an MVA, or if the locale is street or highway (4), assume the pole mentioned is a telephone pole or light pole and use 7878 or do not code if another product is mentioned. These types of poles are excluded from product code 1865.

Q: When and how do we report injuries associated with "cement"?
A: Code all injuries associated with cement. Code cement as household structures (1876) if it is being used as a construction material. A finished structure made of cement should be coded with a specific product code (walls) or if there is no specific product code (such as sidewalks), use 7878.

Q: When should the code for construction materials be used to code items such as pieces of tin,wood, brick or cement?
A: In general, such items are reportable using product code 7878. Use the construction materials code only when there is indication that the material is being used or is planned to be used in a construction project

Q: When should we use the various codes for two-wheeled vehicles (bicycles)?
A: If the vehicle has no motor, use the code for bicycles (5040) unless the record specifically states mountain bike (all terrain bike), and then use the mountain bike code (5033).
A: If the vehicle has a motor, use one of the following codes: 1) if the vehicle is described as a dirt bike or trail bike, use the dirt bike code (5036). 2) if the rider pedals and uses the motor only for assistance, use the moped code (3215). 3) if the vehicle is described as a minibike or pocket bike, use the minibike code (5035).

Q. When should I use product code 2200 for industrial equipment?
A: Product code 2200 should only be used to cover products used in work environments for which there is no other appropriate product code in the manual.

Q: When should the product code for wrestling be used?
A: The code should be used for injuries associated with participating in or practicing for the sport
of wrestling. The code should not be used for situations where the word wrestling is used to describe playing or fighting. Specifically, use the code when there is any indication of the formal sport. Do not use the code when the locale is home and there is no indication that the victim was practicing the sport.

Q: When should we code signs?
A: If a sign is mentioned in the comment and the locale is street or highway (4), or the scenario involves an MVA, then assume the sign is a traffic sign and do not code. If the sign is specified as being anything other than a traffic sign, use product code 1738 ­ public use items.

Q: What product code should be used for grass?
A: When coding grass (e.g.., patient slipped on grass), use product code 7878.

Q: How should we code a new consumer product that does not have a product code in the manual?
A: If you believe a case involves a consumer product, but you cannot determine an appropriate product code, you may use code 9999 temporarily. NEISS Headquarters staff will review these cases and determine whether a current NEISS product code can be used, or a new product code should be added to the Manual. In either case, your NEISS representative will contact you after reviewing the case.

Q: How should we code the component part of a product? For example, how should I code a car window or a car door?
A: Do not code a component part separately. Use the code for the entire product. In the example, a car window or car door would be coded as the car (1901).

Q: Should we code batteries when they are mentioned as a part of another product (e.g.., hot batteries in a flashlight or a battery in an automobile)?
A: Batteries are an exception to the component part rule, and should be coded separately from the product. For the examples above, both the flashlight (0639) and the batteries (0884) should be coded, and both the automobile (1901) and the battery (0884) should be coded.

Q: How should safety playground surfacing be coded?
A: If the victim falls from an item of playground equipment to a safety surface below (e.g. mulch, manufactured mats, pea gravel, etc.), code the item of playground equipment and mention the type of surfacing in the comment line. If no equipment is mentioned, do not code the surfacing.

Lesson Topics


FAQ - Coding Diagnosis and/or Body Parts

Q: When should I use the codes for poisoning, aspiration, ingestion, foreign body and anoxia?
A: Use poisoning (68)
for ingestion of a soluble substance and inhalation of vapors, gases or fumes, except carbon monoxide and smoke from fires.
A: Use
aspiration (42) when a substance is caught in the nose, throat or lungs (e.g. choked on a dime). Also use aspiration when the patient choked on a liquid and the record indicates the victim aspirated.
A: Use
ingestion (41) when above diagnoses do not apply, and the victim has swallowed a non-soluble substance (e.g. swallowed a dime).
A: Use anoxia (65)
when above diagnoses do not apply but the victim was unable to obtain sufficient oxygen either because breathing was hampered (e.g. suffocation, strangulation) or not enough oxygen was available (e.g. carbon monoxide, smoke from fires).
A: Use foreign body (56) when above diagnoses do not apply and object is embedded in victim by force (splinter
lodged in arm).

Q: When should the body part code 84 - (25-50% of body) be used?
A: In general, code the specific body part
(and injury) associated with the most severe injury. Use body part code 84 when a burn injury scenario specifically states that 25-50% of the body was burned, or when the record states that multiple body parts are involved but does not identify any specific body part.

Q: When is it appropriate to use the diagnosis “Not Stated” ?
A: Use the diagnosis code 71 for ‘Other/Not Stated’ when there is no information on the injury. Use this diagnosis code for comments such as ‘Left without being seen’ or ‘Normal Exam’.

Q: How should we code diagnosis when the only information on the ER record is that the patient was suffering pain, swelling, infection or other symptoms?
A: When the only injury information on the ER record is that the patient was suffering pain, swelling, or other symptoms, and there is an external cause of injury, code the diagnosis as “Other/Not Stated” (71), and mention the pain, swelling, or other symptom in the ‘Diagnosis Other’ narrative field.

Q: What diagnosis code should be used for insect bites or animal bites ­ dermatitis, poison, or other?
A: Use the diagnosis code 71 for ‘Other/Not Stated’ unless a more specific diagnosis is provided in the ED record. Where dermatitis or poisoning is specified, use the more specific diagnosis code.

Q: How should we code the diagnosis for excessive alcohol consumption?

Q: How should we code head injuries?
A: When coding head injuries
, code the most specific diagnosis given. When there is no specific diagnosis for a head injury, it should be coded as an internal organ injury (62). Coding the most specific diagnosis should not take precedence over coding the most severe injury. For example, “internal” head injuries such as subdural hematoma, hemorrhaging, etc. should also be coded as internal organ injury (62). If the diagnosis only states ‘hematoma to the head’, then the diagnosis should be coded as hematoma (58). When there are two injuries even to the head, code the most severe.

Q: How do we code the diagnosis of “foreign body sensation”?
A: If the foreign body
sensation is from ingesting a substance, use the diagnosis code for aspiration (42). If the foreign body sensation is mentioned (such as may occur with conjunctivitis), with no external cause or event, the case is considered out of scope.

A: If a rash is described in the ER record as hives or urticaria, use the diagnosis code 71 for "Other/Not Stated", and mention the hives or urticaria in the "Diagnosis Other" narrative field.

Q: How should we code a diagnosis when the record states that a specific diagnosis is "possible" or is being "ruled out"?
A: When the record states that a diagnosis is "possible" or it is being "ruled out", code the possible diagnosis only if there is no other specific diagnosis to code.
