Code Description

ICD-10 M67.359 is a billable code used to indicate a diagnosis of transient synovitis, unspecified hip.

Key Diagnostic Point:

Transient synovitis of the hip is a self-limiting inflammatory condition characterized by the inflammation of the synovial membrane surrounding the hip joint. It is most commonly seen in children, particularly those aged 3 to 10 years, and often presents with hip pain, limping, and reduced range of motion. The etiology is often idiopathic, but it can be associated with viral infections or trauma. Clinically, patients may exhibit symptoms such as hip pain that can radiate to the knee, fever, and a reluctance to bear weight on the affected leg. Diagnosis is typically made through clinical evaluation and imaging studies, such as ultrasound or MRI, which may reveal joint effusion. Treatment is generally conservative, focusing on rest, analgesics, and physical therapy, with most cases resolving spontaneously within a few weeks. However, it is crucial to differentiate transient synovitis from more serious conditions such as septic arthritis or Perthes disease, which may require more aggressive intervention.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other hip disorders like septic arthritis and Perthes disease.
  • Variability in presentation and symptomatology among different age groups.
  • Need for imaging studies to confirm diagnosis.
  • Potential for misdiagnosis due to overlapping symptoms with other conditions.

Audit Risk Factors

  • Inadequate documentation of clinical findings.
  • Failure to differentiate from septic arthritis.
  • Lack of imaging results in the medical record.
  • Inconsistent treatment plans documented.

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Detailed history of present illness, physical examination findings, and imaging results.

Common Clinical Scenarios

A child presenting with hip pain and limping after a recent viral illness.

Billing Considerations

Ensure that differential diagnoses are ruled out, particularly septic arthritis.

Orthopedics

Documentation Requirements

Comprehensive evaluation of hip joint function, imaging studies, and treatment plans.

Common Clinical Scenarios

An adolescent with hip pain and limited range of motion following a sports injury.

Billing Considerations

Document any surgical interventions if they occur, as this may change coding.

Coding Guidelines

Inclusion Criteria

Use M67.359 When
  • According to ICD
  • 10 coding guidelines, M67
  • 359 should be used when the specific hip affected is not documented
  • Coders should ensure that the documentation supports the diagnosis and that other potential conditions are ruled out

Exclusion Criteria

Do NOT use M67.359 When
No specific exclusions found.

Specialty Considerations

Orthopedic specialists may perform this procedure more frequently.

Frequently Asked Questions

What are the common symptoms of transient synovitis?

Common symptoms include hip pain, limping, reduced range of motion, and sometimes fever. Symptoms often follow a viral illness.

How is transient synovitis diagnosed?

Diagnosis is primarily clinical, supported by imaging studies such as ultrasound or MRI to assess for joint effusion and rule out other conditions.
