About S11.9

S11.9 is the ICD-10-CM diagnosis code for open wound of unspecified part of neck. It belongs to category S11 (open wound of neck), block S10-S19 (injuries to the neck) 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 6 subcodes must be used instead.

Within S11, choose S11.9 (unspecified part of neck) only when documentation doesn't support a more specific option: larynx and trachea (S11.0), thyroid gland (S11.1), pharynx and cervical esophagus (S11.2) and other specified parts of neck (S11.8).

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.
