Inj musc/fasc/tend at shldr/up arm, right arm, subs

This code signifies a subsequent encounter for an injury to muscles, fascia, or tendons in the right shoulder or upper arm, excluding those specifically categorized elsewhere (e.g., rotator cuff, biceps). It indicates that the patient is receiving active treatment or follow-up care for a previously diagnosed injury to these soft tissues.

This code is appropriate for follow-up visits, rehabilitation sessions, or repeat injections for a right shoulder/upper arm muscle, fascia, or tendon injury that is not a sprain, strain, or specific named injury. It applies when the patient is still undergoing treatment for the initial injury, beyond the initial acute phase.

• Ensure the encounter is for active treatment or healing of a previously diagnosed injury, not a new injury or sequela.
• Verify laterality (right arm) and the specific anatomical region (shoulder and upper arm level).
• Confirm that the injury type is "other" and not better described by a more specific S46 code (e.g., S46.0-S46.81-).
