Strain of muscle and tendon of unsp wall of thorax, sequela

This code signifies a long-term or late effect resulting from a previous injury to the muscles or tendons of the chest wall, where the specific location on the chest wall is not documented. It indicates that the patient is still experiencing symptoms or complications directly attributable to that past strain.

Use this code when documenting a patient presenting with chronic pain, limited range of motion, or other persistent issues in the chest wall, and the medical record clearly links these issues to a previously sustained muscle or tendon strain. This code is appropriate when the initial acute injury has resolved, but its lasting effects are still being treated or evaluated.

• Always ensure the medical record explicitly states the condition is a "sequela" or "late effect" of a prior strain.
• If the specific wall (e.g., anterior, posterior) is documented, a more specific S29.01- code should be used.
• This code requires an additional code to describe the specific nature of the sequela, if applicable (e.g., chronic pain).
