Take These Simple Steps To Soothe Burn Coding Confusion

Tip: The burn's location is crucial to choosing the right ICD-9 code
When you-re faced with filing a burn claim, asking three essential questions can make it easy for you to find the correct codes.
Clear the smoke: Before you assign a diagnosis code, you-ll need to know the burn location, the burn degree, and the percentage of body surface burned.
1. Location. First, you should use codes 941-946 -to code the burn by body location,- says Lisa Center, quality coordinator with Freeman Health System in Joplin, Mo. For example, if a patient has a burn on her hand, you know to begin your coding with the 944 series.
2. Degree. When reporting a diagnosis from the 941-946 series, you must select a fourth digit, Center says. Codes 941-946 each list six fourth-digit options to indicate the degree of the patient's burn, including 0 (unspecified), 1-3 (first, second or third degree), 4 (deep necrosis of underlying tissues without mention of loss of a body part), and 5 (deep necrosis of underlying tissues with loss of a body part).
Important: You should code for only the highest-level burn when you report multiple burns of differing degrees (severity) in the same area.
3. Precise location: For ICD-9 codes 941-945, you must code out to the fifth digit to indicate the precise location of the patient's burn.
Example: A patient has a second-degree burn on his ankle. You would report 945.23 (Burn of lower limb[s]; blisters, epidermal loss [second degree]; ankle). Once again, higher-degree burns take precedence over lesser-degree burns in the same general anatomic area.
Uncover Rules for Unspecified Location If the family physician's documentation does not specify the location of the patient's burn but does indicate the extent of body surface burned, you should select a 948 code (Burns classified according to extent of body surface involved).
First step: To report the correct 948 code, you must first select a fourth digit to indicate the percentage of the total body surface burned, Center says. Then, you should use a fifth digit to indicate what percentage of the body surface includes a third-degree burn, says Linda Martien, coding consultant with National Healthcare Review in Woodland Hills, Calif.
Avoid this mistake: Coders often stumble over the fifth digit for 948 because they mistakenly think the fifth digit indicates the percentage of the burned area that is third-degree. In fact, you should select the fifth digit that indicates the percentage of the total body surface area with third-degree burns.
If you use 948 because the FP did not specify location, but the patient has no third-degree burns, report 948.x0 (... less than 10 percent or unspecified) to indicate that there are no third-degree burns.
Last resort: If documentation doesn't specify a burn location or the extent of [...]
