Partial traumatic transphalangeal amputation of thmb, subs

This code signifies a partial traumatic amputation of an unspecified thumb, meaning only a portion of the thumb was severed due to an injury, not the entire digit. The "subsequent encounter" designation indicates that this code is used for follow-up care after the initial treatment of the injury.

Use this code for any ongoing treatment, such as wound care, physical therapy, or monitoring for complications, related to a partial traumatic amputation of an unspecified thumb. This applies after the patient has received initial active treatment for the injury.

• Ensure documentation clearly states "partial" amputation and specifies the "thumb."
• Verify the encounter is for follow-up care, not the initial treatment of the injury.
• Confirm the laterality (left or right) is truly unspecified in the medical record before using this code.
