About S11.10

S11.10 is the ICD-10-CM diagnosis code for unspecified open wound of thyroid gland. 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 3 subcodes must be used instead.

Within S11.1, choose S11.10 (Unspecified open wound of thyroid gland) only when documentation doesn't support a more specific option: laceration without foreign body of thyroid gland (S11.11), laceration with foreign body of thyroid gland (S11.12), puncture wound without foreign body of thyroid gland (S11.13), puncture wound with foreign body of thyroid gland (S11.14) and open bite of thyroid gland (S11.15).

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.
