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

This code indicates a long-term or residual effect resulting from a previous injury to the muscles or tendons located in the anterior chest wall. These sequelae can manifest as chronic pain, weakness, or limited range of motion in the affected area, persisting after the initial acute phase of the strain has resolved.

Use this code when documenting a patient presenting with persistent symptoms directly attributable to a past strain of the chest wall muscles or tendons. This is appropriate for follow-up visits addressing chronic issues stemming from the original injury, rather than the initial acute injury itself.

• 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 chronic nature of the condition and its direct relation to a prior strain.
• Do not use for acute or subacute strains; those require different codes from the S29.01- series.
