Congenital metatarsus primus varus, right foot

This code describes a congenital foot deformity affecting the right foot, specifically an inward deviation of the first metatarsal bone. This condition is present at birth and results in an abnormal angulation of the great toe relative to the other toes, often contributing to bunion formation later in life.

Use this code when documentation explicitly states a diagnosis of congenital metatarsus primus varus affecting the patient's right foot. This diagnosis is typically made by a pediatrician or orthopedist based on physical examination and imaging studies (e.g., X-rays) confirming the abnormal metatarsal angulation.

• Ensure documentation specifies "congenital" to differentiate from acquired forms of metatarsus varus.
• Verify laterality (right foot) is clearly documented; separate codes exist for the left and bilateral involvement.
• Consider co-occurring conditions like hallux valgus (bunion) which may require additional coding.
