T20.0Burn of unspecified degree of head, face, and neck

T20.0 is the ICD-10-CM diagnosis code for burn of unspecified degree of head, face, and neck. It belongs to category T20 (burn and corrosion of head, face, and neck), block T20-T25 (burns and corrosions of external body surface, specified by site) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

Within T20, choose T20.0 (Burn of unspecified degree of head, face, and neck) only when documentation doesn't support a more specific option: burn of first degree of head, face, and neck (T20.1), burn of second degree of head, face, and neck (T20.2), burn of third degree of head, face, and neck (T20.3), corrosion of unspecified degree of head, face, and neck (T20.4), corrosion of first degree of head, face, and neck (T20.5), corrosion of second degree of head, face, and neck (T20.6) and corrosion of third degree of head, face, and neck (T20.7).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Use an additional code for: external cause code to identify the source, place and intent of the burn (X00-X19, X75-X77, X96-X98, Y92).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
