Sprain of interphalangeal joint of left middle finger, subs

This code signifies a ligamentous injury to the joint between the phalanges of the left middle finger, specifically when the patient is receiving follow-up care for the initial sprain. This could involve treatment such as physical therapy, cast changes, or monitoring of healing.

Apply this code for patients presenting for ongoing management of a previously diagnosed sprain of the interphalangeal joint of their left middle finger. This includes visits for rehabilitation, re-evaluation of the injury, or management of complications during the healing phase.

• Ensure documentation clearly indicates "subsequent encounter" for the sprain, not an initial injury.
• Verify the specific finger (middle) and side (left) are accurately documented.
• Do not use for initial diagnosis or sequelae of the sprain.
