Code Description

ICD-10 M67.252 is a billable code used to indicate a diagnosis of synovial hypertrophy, not elsewhere classified, left thigh.

Key Diagnostic Point:

Synovial hypertrophy refers to the abnormal enlargement of the synovial membrane, which lines the joints and tendon sheaths. This condition can occur due to various underlying causes, including inflammatory processes, mechanical stress, or degenerative changes. In the left thigh, synovial hypertrophy may be associated with conditions such as tenosynovitis, where inflammation of the tendon sheath occurs, often due to repetitive motion or injury. Patients may present with localized swelling, pain, and reduced range of motion in the affected area. Diagnosis typically involves clinical examination, imaging studies such as ultrasound or MRI, and sometimes synovial fluid analysis. Treatment options may include conservative measures like rest, ice, and anti-inflammatory medications, or more invasive procedures such as corticosteroid injections or surgical intervention to remove excess synovial tissue. Accurate coding for synovial hypertrophy is essential for proper reimbursement and to reflect the complexity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between various types of synovial disorders.
  • Need for precise documentation of the affected area.
  • Potential overlap with other codes related to joint and tendon conditions.
  • Variability in clinical presentation and treatment options.

Audit Risk Factors

  • Inadequate documentation of the clinical findings.
  • Failure to specify the affected joint or tendon.
  • Lack of supporting imaging studies.
  • Inconsistent coding of related conditions.

Coding Guidelines

Inclusion Criteria

Use M67.252 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the code is used only when synovial hypertrophy is confirmed and not due to other specified conditions
  • Documentation must support the diagnosis and any associated treatments

Exclusion Criteria

Do NOT use M67.252 When
No specific exclusions found.

Clinical Scenario

Used when performing an aspiration of the left thigh joint due to synovial hypertrophy.

Documentation Requirements

Document the indication for the procedure, the amount of fluid removed, and any findings.

Specialty Considerations

Orthopedic specialists should ensure that imaging is available to support the need for the procedure.

Frequently Asked Questions

What is synovial hypertrophy?

Synovial hypertrophy is the abnormal thickening of the synovial membrane, often due to inflammation or irritation, leading to joint swelling and pain.

How is synovial hypertrophy diagnosed?

Diagnosis typically involves clinical examination, imaging studies like MRI or ultrasound, and sometimes analysis of synovial fluid.

What are the treatment options for synovial hypertrophy?

Treatment may include conservative measures such as rest and anti-inflammatory medications, or more invasive options like corticosteroid injections or surgery.
