Strain of musc/fasc/tend at thigh level, unsp thigh, sequela

This code signifies a chronic or late-effect injury involving a muscle, fascia, or tendon in the thigh, excluding the quadriceps, adductor, or hamstring groups. The specific muscle or tissue involved is known, but the exact thigh (left or right) is not documented. This diagnosis indicates that the initial injury has resolved, but residual symptoms or complications persist.

Apply this code when documentation clearly indicates a sequela (e.g., chronic pain, weakness, limited range of motion) resulting from a previously sustained strain to a specified, non-quadriceps, non-adductor, non-hamstring muscle, fascia, or tendon of the thigh. This is appropriate for follow-up encounters addressing the long-term effects of such an injury, where the initial acute phase has passed.

• This "S" seventh character indicates a sequela, meaning the patient is receiving care for the residual effects of a previous injury.
• Ensure the documentation specifies a muscle, fascia, or tendon other than quadriceps, adductor, or hamstring.
• If the laterality (left or right thigh) is documented, a more specific code should be used.
