Strain extn musc/fasc/tend l mid finger at wrs/hnd lv, subs

This code signifies a non-traumatic injury to the extensor muscles, fascia, or tendons of the left middle finger, specifically at the wrist or hand level. It indicates an overstretching or tearing of these tissues, resulting in pain, swelling, and impaired finger movement. This particular code is used for follow-up care after the initial injury.

Use this code for patients presenting for follow-up appointments, such as physical therapy, re-evaluation, or medication refills, related to a previously diagnosed strain of the left middle finger extensor structures. This applies when the patient is in the healing phase and not experiencing an acute injury.

• Ensure documentation clearly states "left middle finger" and "extensor" structures.
• Verify the encounter is for subsequent care, not the initial injury or sequela.
• Confirm the injury location is at the "wrist and hand level" as opposed to the forearm or finger tip.
