Strain of musc/fasc/tend at shldr/up arm, left arm, sequela

This code signifies a chronic or late-effect condition resulting from a previous strain injury to muscles, fascia, or tendons in the left shoulder or upper arm, excluding the rotator cuff. This could involve persistent pain, weakness, or functional limitation long after the initial acute injury has healed. The "sequela" designation indicates that the current problem is a residual effect of the original strain.

Use this code when documenting a patient presenting with ongoing symptoms directly attributable to a past strain of the non-rotator cuff muscles, fascia, or tendons of the left shoulder or upper arm. This would apply to conditions like chronic tendinopathy, persistent muscle weakness, or restricted range of motion stemming from an old injury. It is appropriate when the acute phase of the original strain has passed, and the current encounter addresses the long-term consequences.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a previous strain injury of the specified anatomical site.
• Verify that the affected muscles, fascia, or tendons are not part of the rotator cuff, as those have specific codes.
