M20.5Other deformities of toe(s) (acquired)

M20.5 is the ICD-10-CM diagnosis code for other deformities of toe(s) (acquired). It belongs to category M20 (acquired deformities of fingers and toes), block M20-M25 (other joint disorders) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 1 subcodes must be used instead.

Within M20, choose M20.5 (Other deformities of toe(s) (acquired)) only when documentation doesn't support a more specific option: deformity of finger(s) (M20.0), Hallux valgus (acquired) (M20.1), Hallux rigidus (M20.2), Hallux varus (acquired) (M20.3), other hammer toe(s) (acquired) (M20.4) and acquired deformities of toe(s), unspecified (M20.6).

To report this condition, pick the subcode that matches the documentation: M20.5X ((acquired)).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
