Official ICD-10-CM descriptor (FY2026)
Burns classified according to extent of body surface involved
T31 is a category heading, not a billable code. CMS does not accept it on a claim; report one of the more specific codes beneath it.
Notes
- This category is to be used as the primary code only when the site of the burn is unspecified. It should be used as a supplementary code with categories T20-T25 when the site is specified.
