About S76.3
S76.3 is the ICD-10-CM diagnosis code for injury of muscle, fascia and tendon of the posterior muscle group at thigh level. It belongs to category S76 (injury of muscle, fascia and tendon at hip and thigh level), block S70-S79 (injuries to the hip and thigh) 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 4 subcodes must be used instead.
Within S76 (injury of muscle, fascia and tendon at hip and thigh level), S76.3 is specifically for injury of muscle, fascia and tendon of the posterior muscle group at thigh level. Related codes cover muscle, fascia and tendon of hip (S76.0), quadriceps muscle, fascia and tendon (S76.1), adductor muscle, fascia and tendon of thigh (S76.2), other specified muscles, fascia and tendons at thigh level (S76.8) and unspecified muscles, fascia and tendons at thigh level (S76.9).
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.
