Q65.2 Congenital dislocation of hip, unspecified

Name of the Condition

• Congenital Dislocation of Hip, Unspecified

Summary

Congenital dislocation of the hip, unspecified, is a condition present at birth where the femoral head is not properly seated within the acetabulum of the hip joint. This results in joint instability and can affect hip development if left untreated. The term "unspecified" indicates that the documentation does not specify whether the dislocation is unilateral or bilateral.

Causes

The exact cause is not fully understood, but it may involve genetic factors, intrauterine positioning, or abnormal fetal development. A family history of hip dysplasia can increase risk.

Risk Factors

• Female gender
• Breech birth position
• Family history of hip deformities
• Firstborn status
• Oligohydramnios (reduced amniotic fluid)

Symptoms

• Asymmetry in skin folds around the thigh or buttocks
• Limited range of motion in the hip
• Leg length discrepancy
• Clicking or popping sounds during hip movement
• Limp or abnormal gait in older infants

Diagnosis

Physical examination, including tests for hip stability and range of motion, is the initial step. Imaging studies like ultrasound (for infants) or X-rays (for older children) confirm structural abnormalities. Early screening is critical for timely intervention.

Treatment Options

• Pavlik harness or similar orthotic devices for infants to stabilize the hip
• Closed or open surgical procedures

Prognosis and Follow-Up

Early diagnosis and treatment improve outcomes. Regular follow-up is needed to monitor hip development and address any residual issues.

Complications

• Untreated cases may lead to chronic hip instability
• Development of degenerative joint disease in adulthood
• Persistent gait abnormalities

Lifestyle & Prevention

• Routine newborn hip screening to detect issues early
• Proper positioning techniques for infants (e.g., avoiding forced hip extension)
• Follow-up care as recommended by healthcare providers

When to Seek Professional Help

Seek medical attention if you observe asymmetry in skin folds, limited hip movement, or a limp in an infant. Early evaluation is essential for effective management.

Tips for Medical Coders

Document whether the dislocation is unilateral or bilateral when possible, as this impacts coding specificity. For unspecified cases, use Q65.2. Ensure documentation supports the congenital nature of the condition and any associated risk factors or findings.
