W92 — Exposure to excessive heat of man-made origin
W92 is a non-billable header ICD-10-CM code for exposure to excessive heat of man-made origin. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

The appropriate 7th character is to be added to code W92

Other codes that can never be billed with W92
These codes carry an Excludes1 note pointing at W92. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W92 alone.
Risk adjustment
W92 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How W92 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to W92.
- Heat›due to›man-made conditions
- Radiation›infrared›excessive heat from
- Radiation›welding arc, torch, or light›excessive heat from
- Exposure›excessive›heat NEC›man-made
