Partial traumatic trnsphal amputation of right thumb, init

This code signifies a traumatic injury to the right thumb where a portion of the phalanx has been severed or torn away, but not the entire digit. This type of amputation is incomplete, meaning some tissue connection remains, or the amputation occurs through a joint of the phalanx. It specifically indicates the initial treatment for this injury.

This code is appropriate for documenting the initial presentation and treatment of a patient who has sustained a partial traumatic amputation of their right thumb. This includes scenarios where the patient presents to the emergency department, urgent care, or a physician's office immediately following the injury. It should be used for the first encounter related to this specific injury.

• Ensure documentation clearly specifies "partial" and "transphalangeal" to differentiate from complete or other types of amputations.
• Verify the laterality is "right thumb" and that this is indeed the "initial encounter" for treatment.
• Look for associated documentation of the cause of injury to assign an external cause code (V00-Y99) if available.
