Complete traumatic MCP amputation of left thumb, subs

This code signifies the complete traumatic removal of the left thumb at the metacarpophalangeal (MCP) joint, meaning the entire thumb distal to this joint was severed due to an injury. This specific code is used when the patient is receiving follow-up care for this amputation after the initial treatment of the injury.

Use this code for subsequent encounters when a patient is being seen for complications, healing, or rehabilitation related to a complete traumatic amputation of their left thumb at the MCP joint. This includes visits for wound care, prosthetic fitting, physical therapy, or management of chronic pain stemming from the amputation.

• Ensure the documentation clearly specifies "complete" amputation and the exact location as the metacarpophalangeal joint of the left thumb.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Verify the laterality (left thumb) is explicitly documented to support this specific code.
