Lacerat intrinsic musc/fasc/tend finger at wrs/hnd lv, subs

This code signifies a tear or cut to the deep muscles, connective tissue, or tendons within a finger other than the thumb, specifically located at the wrist or hand level. This injury affects the structures responsible for fine motor control and movement of the digits.

Use this code for follow-up encounters for a patient receiving active treatment for a laceration to the intrinsic muscles, fascia, or tendons of the index, middle, ring, or little finger. This includes subsequent visits for wound care, physical therapy, or monitoring healing after the initial injury.

• Ensure documentation specifies "other finger" (not thumb) and the injury location is at the wrist or hand level.
• The "D" seventh character indicates a subsequent encounter for active treatment.
• Confirm the laceration involves intrinsic structures, not just superficial skin.
