Partial traumatic trnsphal amputation of thmb, sequela

This code describes the long-term effects or complications arising from a partial traumatic amputation across the phalanx of an unspecifed thumb. This means the thumb was not completely severed, but a portion of the bone and soft tissue was lost due to trauma, and the patient is now experiencing residual issues related to that injury.

This code is used when documenting a patient presenting with a sequela (e.g., chronic pain, stiffness, deformity, functional limitation) directly attributable to a past partial traumatic transphalangeal amputation of an unspecified thumb. It is appropriate for follow-up encounters after the initial healing phase of the acute injury.

• Always assign an additional code to specify the nature of the sequela (e.g., pain, nonunion, malunion, functional impairment).
• Ensure documentation clearly links the current condition to the previous partial traumatic amputation.
• This code is for an unspecified thumb; if the laterality (left or right) is known, a more specific code should be used.
