Unsp inj musc/fasc/tend at shldr/up arm, left arm, sequela

This code signifies a long-term or late-effect condition resulting from an unspecified injury to muscles, fascia, or tendons in the left shoulder or upper arm. The original acute injury is no longer present, but its lasting consequences are being addressed.

Use this code when documenting a patient presenting with a chronic issue, such as persistent pain, weakness, or limited range of motion, that is directly attributed to an old, unspecified injury of the muscles, fascia, or tendons in the left shoulder or upper arm. This applies when the original injury itself is not being treated, but rather its sequelae.

• Always sequence this code after the code(s) describing the specific sequela (e.g., chronic pain, muscle atrophy).
• Ensure documentation clearly links the current condition to a past, unspecified injury of the left shoulder/upper arm muscles, fascia, or tendons.
• Avoid using this code for acute injuries; it is strictly for sequelae.
