Inj flexor musc/fasc/tend l idx fngr at wrs/hnd lv, sequela

This code signifies a long-term complication or residual effect from a previous injury to the flexor muscles, fascia, or tendons of the left index finger, specifically at the wrist or hand level. This could include chronic pain, stiffness, weakness, or limited range of motion resulting from an earlier trauma.

Use this code when documenting a patient presenting for treatment of a current condition that is a direct consequence of a past injury to the specified flexor structures of the left index finger. This applies to follow-up encounters for conditions like chronic tenosynovitis, scar tissue formation, or persistent functional deficits after the initial acute injury has healed.

• Always sequence this code after the code(s) describing the specific sequela being treated (e.g., M24.542 for contracture).
• Ensure documentation clearly links the current condition to a previous injury of the left index finger flexor structures.
• Do not use for acute injuries; this code is exclusively for late effects or complications.
