2025 ICD-10-CM code Q66

Congenital deformities of the feet.

Refer to the official ICD-10-CM coding guidelines for detailed instructions on assigning codes from this chapter.Ensure the appropriate level of specificity is used for the diagnosed condition.

Medical necessity is established by the presence of a congenital foot deformity impacting the child's mobility, function, or overall well-being, necessitating medical intervention such as casting, bracing, or surgery.

The clinical responsibility lies with the physician or healthcare professional diagnosing and managing the congenital foot deformity. This might include orthopedists, pediatricians, or other specialists depending on the complexity and severity of the condition.

IMPORTANT Q66.0 (Congenital talipes equinovarus), Q66.1 (Congenital talipes calcaneovarus), Q66.2 (Congenital metatarsus varus), Q66.6 (Other congenital valgus deformities of feet) are more specific codes within this category.Consider using these if more detail is available.

In simple words: This code describes birth defects affecting the shape or position of the feet.It does not include foot problems that develop later in life.

This ICD-10-CM code encompasses various congenital deformities affecting the feet.It excludes reduction defects of the feet (Q72.-), acquired valgus deformities (M21.0-), and acquired varus deformities (M21.1-).

Example 1: A newborn infant presents with clubfoot (talipes equinovarus), requiring casting and/or surgical intervention. Code Q66.0 would be appropriate., A child is diagnosed with a congenital metatarsus varus, characterized by inward turning of the forefoot. Code Q66.2 would be assigned., An adolescent is found to have an unusual congenital valgus deformity of the feet not fitting the other more specific codes. Code Q66.6 would be used.

Detailed clinical documentation is required, including the type of foot deformity (e.g., talipes equinovarus, metatarsus varus), physical examination findings, imaging studies (if any), and treatment plan.Documentation should clearly establish the congenital nature of the deformity.
