Strain of extensor musc/fasc/tend finger at wrs/hnd lv, subs

This code signifies a muscle, fascia, or tendon strain affecting an extensor structure of any finger other than the thumb, located at the wrist or hand level. It indicates that the patient is in the healing phase of the injury, receiving follow-up care after the initial treatment.

Apply this code for subsequent encounters when a patient presents for ongoing management, physical therapy, or re-evaluation of a previously diagnosed extensor strain of a finger (excluding the thumb) at the wrist or hand. This includes visits for monitoring recovery, assessing treatment effectiveness, or addressing complications during the healing process.

• Ensure the documentation specifies an extensor strain of a finger other than the thumb.
• Verify the encounter is for follow-up care, not the initial injury.
• Confirm the injury location is at the wrist or hand level.
