Lacerat extn musc/fasc/tend r rng fngr at wrs/hnd lv, subs

This code signifies a cut or tear affecting the extensor muscle, its surrounding fascia, and the tendon of the right ring finger. The injury is located specifically at the wrist or hand level, and this code is used for follow-up care after the initial treatment.

Apply this code when documenting subsequent encounters for a patient who previously sustained a laceration to the extensor structures of their right ring finger. This includes visits for wound care, physical therapy, monitoring healing, or addressing complications after the initial repair.

• Ensure the documentation clearly specifies the right ring finger and the wrist/hand level.
• Confirm this is not the initial encounter for the injury; look for "subsequent encounter" or similar phrasing.
• Always code the underlying cause of the laceration (e.g., W20.0XXA for striking against an object) as a secondary diagnosis.
