Strain extensor musc/fasc/tend l idx fngr at forarm lv, subs

This code signifies a muscle, fascia, or tendon strain affecting the extensor structures of the left index finger, specifically at the forearm level. It indicates that the patient is receiving follow-up care for this injury, beyond the initial treatment.

Use this code for subsequent encounters when a patient presents for ongoing management, such as physical therapy, re-evaluation, or follow-up imaging, for a previously diagnosed strain of the extensor muscles, fascia, or tendons of the left index finger originating in the forearm. This applies after the initial treatment phase has concluded.

• Ensure documentation specifies the left index finger and the forearm level of the strain.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Verify the injury is a strain, not a sprain, rupture, or other type of injury.
