Lacerat extn musc/fasc/tend l idx fngr at wrs/hnd lv, sqla

This code signifies a long-term consequence or complication resulting from a past laceration to the extensor muscle, fascia, or tendon of the left index finger, specifically at the wrist or hand level. This could include chronic pain, stiffness, limited range of motion, or other persistent functional deficits directly attributable to the original injury.

Apply this code when documenting a patient presenting with a current sequela (e.g., chronic pain, contracture, weakness) that is a direct result of a previously sustained laceration to the extensor structures of the left index finger. This code is appropriate for follow-up visits addressing these lasting effects, rather than the initial acute injury.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., M24.542 for contracture of left finger).
• Ensure documentation clearly links the current condition to the prior laceration of the left index finger extensor structures.
• Verify the laterality (left) and specific finger (index) are accurately reflected in the medical record.
