Q70

Q70 — Syndactyly

Non-billable headerICD-10-CM

Q70 is a non-billable header ICD-10-CM code for syndactyly. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q70

M20Acquired deformities of fingers and toes
Q70.4Polysyndactyly, unspecified
Q74Other congenital malformations of limb(s)

Code to one of these instead Q70

6 child codes. Green means billable.
