Partial traumatic MCP amputation of right thumb, init

This code signifies a traumatic injury to the right thumb where part of the thumb has been severed at the metacarpophalangeal (MCP) joint level, but not the entire digit. This partial amputation implies that some tissue, such as skin, tendon, or bone, remains connecting the distal part of the thumb to the hand, or a portion of the digit has been lost, but not the entire thumb at that joint.

Use this code for initial encounters when documenting a patient presenting with a fresh, traumatic partial amputation of the right thumb at the MCP joint. This applies to injuries resulting from accidents, machinery, or other external forces where the thumb is not completely detached at this specific joint.

• Ensure documentation clearly specifies "partial" amputation and the "right" thumb at the "MCP joint" level.
• Verify that this is the initial treatment for the injury; subsequent encounters will require a different seventh character.
• Look for associated open wound codes if the amputation site is open and requires debridement or repair.
