Congenital deformities of feet (Q66)

Browse all the diagnosis codes used for congenital deformities of feet (q66). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Clubfoot - A deformed foot in which the foot is plantarflexed, inverted, and adducted.

Equinus Deformity - Plantar declination of the foot.

Flatfoot - Anomaly in which one or more of the arches of the feet are flat.

Hypertelorism - Abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.

Talipes - Deformity in which the foot is misaligned with respect to the TALUS in the ANKLE JOINT. While mostly congenital, as in CLUBFOOT, acquired deformities are included. Acquired talipedes are often associated with other foot deformities such as SYNDACTYLY and POLYDACTYLY.

Talipes Cavus - A foot deformity in which the arch of the foot is high and often the heel adducted.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
