About coding head laceration

The ICD-10-CM code for head laceration is S01.91 (Laceration without foreign body of unspecified part of head). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S01.91.

Within S01.9, choose S01.91 (Laceration without foreign body of unspecified part of head) only when documentation doesn't support a more specific option: unspecified open wound of unspecified part of head (S01.90), laceration with foreign body of unspecified part of head (S01.92), puncture wound without foreign body of unspecified part of head (S01.93), puncture wound with foreign body of unspecified part of head (S01.94) and open bite of unspecified part of head (S01.95).

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.

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