Partial traumatic MCP amputation of right thumb, sequela

This code describes the long-term effects or complications resulting from a partial traumatic amputation of the right thumb at the metacarpophalangeal (MCP) joint. This includes conditions such as chronic pain, stiffness, nerve damage, or functional limitations that persist after the initial healing of the injury.

Use this code when documenting follow-up care for a patient who previously sustained a partial traumatic amputation of the right thumb at the MCP joint, and is now presenting with residual issues directly related to that past injury. This applies to encounters addressing the ongoing consequences, not the initial injury or acute healing phase.

• Always assign a "sequela" code when the patient is being treated for a complication or late effect of an old injury.
• Do not use this code for the initial injury or during the active treatment phase of the acute amputation.
• Consider additional codes for specific sequelae, such as chronic pain (G89.-) or scar formation (L90.5), if applicable and documented.
