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

This code signifies a long-term complication or residual effect stemming from a past injury to the flexor muscles, fascia, or tendons of the right index finger. This injury occurred at the wrist or hand level, and the patient is now presenting with a condition directly resulting from that initial trauma, such as chronic pain, stiffness, or functional limitation.

Apply this code when documenting a patient presenting for treatment of a sequela (e.g., chronic pain, contracture, weakness, scar tissue) directly attributable to a previous injury of the flexor structures of the right index finger at the wrist or hand. This code is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting consequences.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M24.541 for contracture of right finger).
• Ensure documentation clearly links the current condition to a past injury of the right index finger's flexor structures at the specified level.
• Verify laterality (right index finger) and anatomical location (wrist and hand level) are explicitly stated in the medical record.
