Strain flexor musc/fasc/tend r idx fngr at forarm lv, subs

This code signifies a non-traumatic overstretching or tearing of the muscle, fascia, or tendon of the flexor compartment specifically affecting the right index finger, but with the injury located at the forearm level. It indicates that the patient is in the healing phase following the initial injury, receiving active treatment such as physical therapy or medication adjustments.

Apply this code for follow-up encounters when a patient is receiving ongoing care for a previously diagnosed strain of the flexor structures of the right index finger, where the anatomical site of the strain is within the forearm. This includes scenarios like subsequent physical therapy sessions, re-evaluations, or medication management for the healing strain.

• Ensure the documentation specifies the right index finger and the forearm level for the strain.
• Verify that the encounter is for active treatment during the healing phase, indicated by the "D" seventh character.
• Distinguish from initial encounters (A) or sequela (S) for appropriate seventh character assignment.
