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

This code signifies a long-term or residual effect from an injury to muscles, fascia, or tendons in the right shoulder or upper arm, excluding those specifically categorized elsewhere (e.g., rotator cuff, biceps). These sequelae can include chronic pain, weakness, limited range of motion, or functional impairment resulting from a past injury.

Use this code when documenting a current condition that is a direct consequence of a previous injury to unspecified muscles, fascia, or tendons of the right shoulder or upper arm. This applies to follow-up encounters for chronic issues, scar tissue formation, or persistent functional deficits that are no longer in the acute healing phase.

• Always link this sequela code to an external cause code (V00-Y99) if the original injury's cause is known and relevant.
• Ensure documentation clearly states the "sequela" nature of the current condition and its link to a past injury.
• Do not use for acute injuries; refer to the appropriate acute injury codes (S46.891A, S46.891D) for initial or subsequent encounters during active treatment.
