Code Description

ICD-10 Q65.31 is a billable code used to indicate a diagnosis of congenital partial dislocation of right hip, unilateral.

Key Diagnostic Point:

Congenital partial dislocation of the right hip, also known as hip dysplasia, is a condition where the femoral head is not properly seated in the acetabulum of the pelvis. This malformation can lead to instability in the hip joint, which may result in pain, limited mobility, and potential long-term complications such as osteoarthritis if not addressed early. The condition is often diagnosed in infancy or early childhood through physical examination and imaging studies such as ultrasound or X-rays. Treatment typically involves the use of a Pavlik harness or surgical intervention in more severe cases. Early detection and management are crucial to ensure proper hip development and function. This condition is part of a broader category of congenital malformations that can affect the musculoskeletal system, and it may coexist with other congenital anomalies, including those affecting the urinary system, such as renal agenesis or bladder exstrophy.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of the condition.
  • Need for precise documentation of the degree of dislocation.
  • Potential for co-occurring congenital conditions requiring additional coding.
  • Variations in treatment approaches that may affect coding.

Audit Risk Factors

  • Inadequate documentation of clinical findings.
  • Failure to specify laterality (right vs. left).
  • Misclassification of the severity of dislocation.
  • Inconsistent coding of co-occurring conditions.
