In simple words: This code indicates that the patient is missing a great toe due to a past injury or amputation.
Acquired absence of unspecified great toe. This code describes the status of a patient after the loss of a great toe due to amputation or post-traumatic injury.
Example 1: A patient presents for a follow-up visit after a great toe amputation due to complications from diabetes. The code Z89.419 is used to indicate the missing toe., A patient with a history of frostbite and subsequent amputation of the great toe is seen for an unrelated condition. Z89.419 is used as a secondary code to document the missing toe., A patient who had a great toe amputated due to trauma from a car accident years ago presents with phantom limb pain. Z89.419 is used to note the historical amputation.
Medical records should clearly document the circumstances surrounding the loss of the great toe, including the date of the amputation or injury, the cause (e.g., diabetes, trauma, frostbite), and any related complications.
** This code should be used as a secondary code to explain the absence of the great toe when the patient seeks care for other conditions. If the encounter is specifically related to the aftercare of the amputation, a different code might be more appropriate.Code also any follow-up examination (Z08-Z09).
