Code Description

ICD-10 Q66.229 is a billable code used to indicate a diagnosis of congenital metatarsus adductus, unspecified foot.

Key Diagnostic Point:

Congenital metatarsus adductus is a common foot deformity characterized by the inward turning of the forefoot, which can occur in one or both feet. This condition is typically identified at birth and may be associated with other congenital anomalies. The exact etiology is often unknown, but it may be linked to intrauterine positioning or genetic factors. The condition can vary in severity, and while many cases resolve spontaneously, some may require intervention such as physical therapy or corrective footwear. In the context of congenital malformations, it is important to assess for associated conditions, particularly those affecting the urinary system, such as renal agenesis or bladder exstrophy, which may occur in syndromic presentations. Accurate coding is essential for proper management and follow-up care.

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to note associated congenital anomalies
  • Incorrect coding of severity or laterality
  • Lack of follow-up documentation

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation should include detailed physical examination findings, family history, and any associated congenital conditions.

Common Clinical Scenarios

Common scenarios include newborn assessments where metatarsus adductus is identified, and follow-up visits to monitor development.

Billing Considerations

Consideration should be given to the age of the patient and the potential for spontaneous resolution.

Genetics

Documentation Requirements

Genetic documentation should include family history of congenital conditions, genetic testing results, and any syndromic associations.

Common Clinical Scenarios

Scenarios may involve genetic counseling for families with a history of congenital malformations.

Billing Considerations

Geneticists should be aware of the potential for chromosomal abnormalities that may present with similar foot deformities.
