Inj intrinsic musc/fasc/tend thmb at wrs/hnd lv, sequela

This code signifies a long-term complication or residual effect from a previous injury to one of the small muscles, their surrounding fascia, or tendons within an unspecified thumb, specifically at the wrist or hand level. This indicates that the initial acute injury has healed, but the patient continues to experience related issues such as pain, weakness, or limited range of motion.

Apply this code when documenting a patient presenting for treatment of a chronic condition directly resulting from a past injury to an intrinsic thumb muscle, fascia, or tendon. This would include follow-up appointments for ongoing physical therapy, pain management, or surgical intervention to address the sequelae. It is crucial that the initial injury is no longer acute.

• Always use this code as a secondary diagnosis, following a primary code that describes the specific nature of the sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a previous intrinsic thumb injury.
• Verify that the injury location is specified as the thumb at the wrist or hand level, and that the muscle, fascia, or tendon is intrinsic.
