2025 ICD-10-CM code Z89.42
Acquired absence of other toe(s).
The medical necessity for using this code is established when a healthcare provider documents the acquired absence of the specified toe(s) and this information is relevant to the patient's current healthcare encounter.
Clinicians should document the cause of the missing toes, such as trauma, surgical amputation, or other acquired conditions. They should also assess the patient's functional status and any associated complications.
In simple words: This code indicates that a person is missing toes (not the big toe) due to an injury, surgery, or other event that happened after birth.
This code signifies the acquired absence of toes, excluding the great toe. This condition may be due to amputation, post-procedural loss, or post-traumatic loss.
Example 1: A patient presents with an absent second toe due to a previous traumatic amputation following a car accident., A patient with diabetes has developed gangrene in several toes, necessitating surgical amputation.The great toe was not affected., A patient had a portion of his foot amputated in the past which included his 3rd toe.
Documentation should clearly specify the affected toe(s), the cause of the absence (e.g., amputation, trauma), the date of the event, and any related complications or functional limitations.
** Z codes are used to document reasons for encounters. They should be used in conjunction with a procedure code if a procedure is performed.This code is specifically for acquired absence, not congenital absence.
