Strain extn musc/fasc/tend l idx fngr at wrs/hnd lv, sequela

This code signifies a past injury to the extensor muscles, fascia, or tendons of the left index finger, specifically at the wrist or hand level, that has resulted in a lasting complication or condition. This could include chronic pain, weakness, limited range of motion, or other persistent issues stemming from the original strain.

Use this code when documenting a patient presenting with ongoing symptoms directly attributable to a previously sustained strain of the left index finger extensor structures. This applies to follow-up encounters where the acute injury has resolved, but residual effects persist. It is appropriate for conditions like chronic tendinitis, adhesions, or persistent weakness following an initial strain.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., chronic pain, limited range of motion).
• Ensure documentation clearly links the current condition to a past strain of the left index finger extensor.
• Verify the laterality (left) and specific finger (index) are accurately reflected in the medical record.
