Code Description

ICD-10 Q72.13 is a billable code used to indicate a diagnosis of congenital absence of thigh and lower leg with foot present, bilateral.

Key Diagnostic Point:

Congenital absence of the thigh and lower leg with the foot present bilaterally is a rare limb reduction defect characterized by the complete absence of the femur and tibia, while the feet remain intact. This condition can occur as an isolated anomaly or as part of a syndrome involving other congenital malformations. The absence of these segments can lead to significant functional limitations and challenges in mobility, necessitating early intervention and possibly surgical management. The etiology may involve genetic factors, environmental influences, or a combination of both. Clinically, affected individuals may present with a range of associated conditions, including clubfoot, hip dysplasia, or scoliosis, which can complicate the overall management and treatment plan. Accurate diagnosis typically involves imaging studies and a thorough clinical evaluation to assess the extent of limb involvement and any associated anomalies. Multidisciplinary care, including orthopedic, rehabilitation, and genetic counseling, is often required to optimize outcomes for affected children.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and associated conditions
  • Need for detailed clinical documentation
  • Potential for multiple coding options based on associated anomalies
  • Requirement for interdisciplinary collaboration in care

Audit Risk Factors

  • Inadequate documentation of associated congenital anomalies
  • Failure to specify bilateral involvement
  • Misclassification of limb reduction defects
  • Lack of clarity in clinical notes regarding functional limitations

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Pediatric documentation must include detailed descriptions of the child's functional abilities, any associated conditions, and the impact on daily activities.

Common Clinical Scenarios

Common scenarios include assessments for mobility aids, surgical interventions, and rehabilitation plans for children with limb reduction defects.

Billing Considerations

Coders should be aware of the developmental milestones and how the absence of limbs may affect these milestones.

Genetics

Documentation Requirements

Genetic documentation should include family history, potential syndromic associations, and results from genetic testing if applicable.

Common Clinical Scenarios

Scenarios may involve genetic counseling for families, discussions about recurrence risks, and management of syndromic presentations.

Billing Considerations

Consideration of chromosomal abnormalities or syndromes that may present with limb reduction defects is crucial for accurate coding.
