Partial traumatic MCP amputation of left thumb, subs

This code signifies a partial loss of the left thumb at the metacarpophalangeal (MCP) joint due to a traumatic injury. This means some portion of the thumb distal to the MCP joint was amputated, but not the entire thumb. The "subsequent encounter" indicates that the patient is receiving follow-up care for this injury after the initial treatment.

This code is appropriate for encounters where a patient is being seen for ongoing management, healing, or complications related to a previously sustained partial traumatic amputation of their left thumb at the MCP joint. This includes visits for wound care, physical therapy, fitting for prosthetics, or monitoring for infection during the recovery phase.

• Ensure the documentation clearly specifies a partial amputation at the metacarpophalangeal joint of the left thumb.
• Verify the encounter type is for follow-up care, not the initial treatment of the injury.
• Distinguish from complete amputations or amputations at other thumb joints (e.g., interphalangeal).
