Complete traumatic MCP amputation of left thumb, sequela

This code signifies the long-term effects or complications arising from a complete traumatic amputation of the left thumb at the metacarpophalangeal joint. This includes conditions such as phantom limb pain, stump complications, or functional limitations that persist after the initial healing of the amputation.

Use this code for encounters where a patient is being treated for a sequela directly related to a past complete traumatic amputation of their left thumb at the metacarpophalangeal joint. This applies to follow-up care, rehabilitation, or management of chronic issues stemming from the original injury, occurring a year or more after the initial event.

• Always use this code as a secondary diagnosis, with the primary diagnosis reflecting the specific sequela being treated (e.g., phantom limb pain).
• Ensure documentation clearly links the current condition to the historical amputation of the left thumb at the MCP joint.
• Verify the laterality (left thumb) and the specific joint (metacarpophalangeal) are accurately documented to support this code.
