Strain extn musc/fasc/tend r idx fngr at wrs/hnd lv, subs

This code signifies a non-traumatic overstretching or tearing of the extensor muscle, fascia, or tendon specifically affecting the right index finger. The injury is located at the wrist or hand level, and this particular code is used for follow-up care after the initial treatment.

This code is appropriate for encounters where a patient is receiving ongoing treatment, rehabilitation, or follow-up for a previously diagnosed strain of the right index finger's extensor structures. This includes visits for physical therapy, re-evaluation of healing, or management of persistent symptoms after the initial injury.

• Ensure the documentation clearly specifies the right index finger and the wrist/hand level for the extensor strain.
• Verify that the encounter is for subsequent care, not the initial injury.
• Confirm the injury is a strain (overstretching/tear) and not a rupture or laceration, which would require different codes.
