M20.5X9
ICD-10-CMThis code signifies an acquired structural abnormality of one or more toes, not otherwise specified, affecting an unspecified foot. It covers various non-congenital toe deformities that are not explicitly categorized elsewhere, such as hammer toe, claw toe, or mallet toe, when the specific type or laterality is not documented.
Utilize this code when documentation indicates an acquired, unspecified deformity of the toe(s) and the specific foot (left or right) is not identified. This is appropriate for initial encounters where laterality or the precise nature of the deformity is pending further evaluation, or when the medical record simply states "toe deformity" without additional detail.
