Inj musc/fasc/tend at wrs/hnd lv, unsp hand, sequela

This code signifies a long-term complication or residual effect stemming from an injury to a muscle, fascia, or tendon in the wrist or hand, where the specific muscle, fascia, or tendon is known but the hand (left or right) is not documented. It indicates that the initial acute injury has resolved, but the patient continues to experience issues directly related to that past injury.

Apply this code when a patient presents with a chronic condition or permanent impairment of a specified wrist or hand muscle, fascia, or tendon, and the medical record clearly links it to a previous injury. This is appropriate for follow-up encounters addressing the lasting effects of such an injury, rather than the initial acute treatment.

• Ensure documentation explicitly states the condition is a sequela of a previous injury.
• Only use this code when the specific muscle, fascia, or tendon is identified, but the laterality of the hand is not specified.
• Do not use for initial or acute injury encounters; reserve for chronic or residual conditions.
