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

This code signifies a tear or overstretching injury to the extensor muscles, their surrounding fascia, or their tendons specifically located in the right index finger, occurring at the wrist or hand level. This type of injury typically results in pain, swelling, and impaired movement of the affected finger.

Use this code for a patient presenting with an acute injury to the right index finger's extensor mechanism, such as from repetitive strain, sudden forceful extension, or direct trauma. It is appropriate for the initial visit where the injury is first diagnosed and treatment is initiated.

• Ensure documentation specifies the right index finger and the injury location at the wrist and hand level.
• Confirm the encounter is the initial treatment for this specific injury.
• Distinguish from sprains (ligamentous injury) or other finger injuries by verifying extensor muscle/tendon involvement.
