S56.812Strain of other muscles, fascia and tendons at forearm level, left arm

S56.812 is the ICD-10-CM diagnosis code for strain of other muscles, fascia and tendons at forearm level, left arm. It belongs to category S56 (injury of muscle, fascia and tendon at forearm level), block S50-S59 (injuries to the elbow and forearm) 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 S56.81 (strain of other muscles, fascia and tendons at forearm level), S56.812 is specifically for strain of other muscles, fascia and tendons at forearm level, left arm. Related codes cover right arm (S56.811) and unspecified arm (S56.819).

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.
