Code Description

ICD-10 Q65.81 is a billable code used to indicate a diagnosis of congenital coxa valga.

Key Diagnostic Point:

Congenital coxa valga is a deformity characterized by an increased angle between the femoral neck and the femoral shaft, leading to an outward angulation of the hip joint. This condition can result from developmental issues during fetal growth, and it may be associated with other congenital malformations, particularly those affecting the musculoskeletal system. In pediatric patients, coxa valga can lead to gait abnormalities, hip pain, and increased risk of hip dislocation. The condition may be isolated or part of a syndrome that includes other congenital anomalies, such as renal agenesis or bladder exstrophy. Diagnosis typically involves physical examination and imaging studies, such as X-rays, to assess the degree of angulation and any associated skeletal abnormalities. Treatment options may include observation, physical therapy, or surgical intervention, depending on the severity of the condition and its impact on the child's mobility and quality of life.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of the condition
  • Potential association with other congenital anomalies
  • Need for precise documentation of associated conditions
  • Differentiation from similar musculoskeletal conditions

Audit Risk Factors

  • Inadequate documentation of associated congenital anomalies
  • Failure to specify the severity of the condition
  • Incorrect linkage of diagnosis to treatment procedures
  • Misclassification of the condition with similar codes
