Code Description

ICD-10 M67.31 is a billable code used to indicate a diagnosis of transient synovitis, shoulder.

Key Diagnostic Point:

Transient synovitis of the shoulder is a temporary inflammatory condition affecting the synovial membrane of the shoulder joint. It is characterized by pain, swelling, and limited range of motion, often following minor trauma or overuse. The condition is most commonly seen in children but can occur in adults as well. The inflammation leads to an accumulation of synovial fluid, which can cause discomfort and restrict movement. Diagnosis typically involves a thorough clinical examination, imaging studies such as ultrasound or MRI, and sometimes aspiration of the joint to analyze the synovial fluid. Treatment usually includes rest, ice application, nonsteroidal anti-inflammatory drugs (NSAIDs), and physical therapy. In severe cases, corticosteroid injections may be considered. The prognosis is generally good, with most patients recovering fully within a few weeks. However, recurrent episodes can occur, necessitating careful monitoring and management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating transient synovitis from other shoulder conditions such as rotator cuff injuries or arthritis.
  • Need for precise documentation of symptoms and treatment response.
  • Variability in clinical presentation among different age groups.
  • Potential for overlapping diagnoses that may complicate coding.

Audit Risk Factors

  • Inadequate documentation of the clinical findings.
  • Failure to specify the affected joint.
  • Misdiagnosis or coding of related conditions.
  • Lack of follow-up documentation to support the diagnosis.

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed clinical notes including history, physical examination findings, imaging results, and treatment plans.

Common Clinical Scenarios

Patients presenting with shoulder pain after minor trauma or overuse, particularly in children.

Billing Considerations

Consideration of differential diagnoses such as rotator cuff tears or adhesive capsulitis.

Pediatrics

Documentation Requirements

Thorough history taking, including developmental milestones and activity levels, along with physical exam findings.

Common Clinical Scenarios

Children with acute shoulder pain and limited range of motion following sports activities.

Billing Considerations

Awareness of growth plate involvement and the need for appropriate imaging.

Coding Guidelines

Inclusion Criteria

Use M67.31 When
  • According to ICD
  • 10 coding guidelines, M67
  • 31 should be used when the condition is specifically diagnosed as transient synovitis of the shoulder
  • It is important to document the clinical findings and treatment plan to support the diagnosis

Exclusion Criteria

Do NOT use M67.31 When
  • Exclusion criteria include conditions that are not transient or involve other joints

Related ICD-10 Codes

20610CPT Code

Arthrocentesis, aspiration and/or injection into a major joint or bursa

Clinical Scenario

Used when aspiration of the shoulder joint is performed to relieve symptoms.

Documentation Requirements

Document the indication for the procedure, the amount of fluid removed, and the patient's response.

Specialty Considerations

Orthopedic specialists should ensure that imaging studies support the need for aspiration.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of transient synovitis, improving the accuracy of diagnoses and treatment tracking. This specificity aids in better patient management and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of transient synovitis, improving the accuracy of diagnoses and treatment tracking. This specificity aids in better patient management and resource allocation.

Reimbursement & Billing Impact
