S46.80Unspecified injury of other muscles, fascia and tendons at shoulder and upper arm level

S46.80 is the ICD-10-CM diagnosis code for unspecified injury of other muscles, fascia and tendons at shoulder and upper arm level. It belongs to category S46 (injury of muscle, fascia and tendon at shoulder and upper arm level), block S40-S49 (injuries to the shoulder and upper arm) 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 S46.8, choose S46.80 (Unspecified injury of other muscles, fascia and tendons at shoulder and upper arm level) only when documentation doesn't support a more specific option: strain of other muscles, fascia and tendons at shoulder and upper arm level (S46.81), laceration of other muscles, fascia and tendons at shoulder and upper arm level (S46.82) and other injury of other muscles, fascia and tendons at shoulder and upper arm level (S46.89).

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.
