Inj musc/tend the rotator cuff of unsp shoulder, subs

This code signifies a follow-up encounter for a non-specific injury to the muscles or tendons of the rotator cuff in an unspecified shoulder. It indicates that the initial treatment for the injury has already occurred, and the patient is now receiving ongoing care, such as rehabilitation or monitoring.

Apply this code when a patient presents for a subsequent visit related to a rotator cuff muscle or tendon injury that doesn't fit more specific injury codes (e.g., tear, strain). This is appropriate for follow-up appointments after initial diagnosis and treatment, or during the recovery phase when the specific nature of the injury is not further elaborated.

• Ensure the encounter is truly "subsequent" and not the initial treatment for the injury.
• Always attempt to identify the specific muscle/tendon involved and the laterality (left/right shoulder) if documented.
• Only use this code when more specific rotator cuff injury codes (e.g., S46.01-, S46.02-, S46.04-) are not supported by the documentation.
