Lacerat flexor musc/fasc/tend finger at wrs/hnd lv, init

This code signifies a tear or cut involving the flexor muscles, their surrounding fascia, and the tendons of any finger other than the thumb, specifically occurring at the wrist or hand level. This injury disrupts the structures responsible for bending the affected finger.

Apply this code for acute injuries such as those sustained from sharp objects (e.g., knives, glass) or machinery, resulting in a laceration to the flexor apparatus of a finger (excluding the thumb) within the wrist or hand region. It is appropriate for the initial treatment of such an injury.

• Ensure the documentation specifies a laceration, not just a strain or sprain, and clearly identifies the flexor structures.
• Verify the injury location is at the wrist or hand level, and not more distal (e.g., at the finger itself).
• Confirm this is the patient's initial encounter for this specific injury to justify the "A" seventh character.
