Code Description

ICD-10 M67.2 is a billable code used to indicate a diagnosis of synovial hypertrophy, not elsewhere classified.

Key Diagnostic Point:

Synovial hypertrophy refers to the abnormal enlargement of the synovial membrane, which lines the joints and tendon sheaths. This condition can arise from various underlying causes, including inflammatory diseases, repetitive trauma, or degenerative changes. Clinically, synovial hypertrophy may present with joint swelling, pain, and reduced range of motion. It is often associated with conditions such as tenosynovitis, where inflammation of the tendon sheath occurs, leading to pain and swelling along the tendon. In some cases, synovial hypertrophy can contribute to tendon ruptures, particularly in chronic conditions where the tendon is subjected to excessive stress. Surgical interventions, such as synovectomy or tendon repair, may be necessary to alleviate symptoms and restore function. Accurate diagnosis typically involves imaging studies, such as ultrasound or MRI, to assess the extent of hypertrophy and any associated tendon pathology. Treatment may include corticosteroid injections, physical therapy, or surgical repair, depending on the severity and underlying cause of the condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes leading to synovial hypertrophy.
  • Differentiation from other similar conditions (e.g., tenosynovitis, bursitis).
  • Need for precise documentation of symptoms and imaging findings.
  • Potential for co-existing conditions that may complicate coding.

Audit Risk Factors

  • Inadequate documentation of the underlying cause of synovial hypertrophy.
  • Failure to document associated conditions such as tenosynovitis.
  • Lack of imaging studies to support the diagnosis.
  • Inconsistent coding of surgical procedures related to the condition.

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 joint pain and swelling, particularly in the hands, knees, or wrists, often requiring surgical intervention.

Billing Considerations

Orthopedic surgeons must document the extent of synovial hypertrophy and any associated tendon injuries to justify surgical procedures.

Rheumatology

Documentation Requirements

Comprehensive assessment of inflammatory markers, patient history, and response to treatment.

Common Clinical Scenarios

Patients with autoimmune conditions presenting with joint swelling and pain, requiring management of synovial hypertrophy.

Billing Considerations

Rheumatologists should document the relationship between systemic inflammatory diseases and synovial hypertrophy.

Coding Guidelines

Inclusion Criteria

Use M67.2 When
  • According to ICD
  • 10 guidelines, M67
  • 2 should be used when synovial hypertrophy is documented without a more specific classification
  • Coders must ensure that the diagnosis is supported by clinical findings and imaging results

Exclusion Criteria

Do NOT use M67.2 When
No specific exclusions found.

Documentation Requirements

Document the indication for the procedure, including symptoms and imaging findings.

Specialty Considerations

Orthopedic and rheumatology specialties should ensure clear documentation of the diagnosis and treatment plan.

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conditions like synovial hypertrophy, improving the accuracy of diagnoses and treatment plans. This specificity aids in better tracking of patient outcomes and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of conditions like synovial hypertrophy, improving the accuracy of diagnoses and treatment plans. This specificity aids in better tracking of patient outcomes and resource allocation.

Reimbursement & Billing Impact

Frequently Asked Questions

What is the primary cause of synovial hypertrophy?

Synovial hypertrophy can be caused by various factors, including inflammatory conditions, repetitive trauma, and degenerative changes in the joint.

How is synovial hypertrophy diagnosed?

Diagnosis typically involves a combination of clinical examination, patient history, and imaging studies such as ultrasound or MRI to assess the extent of hypertrophy.

What treatments are available for synovial hypertrophy?

Treatment options may include conservative management with physical therapy and corticosteroid injections, or surgical interventions such as synovectomy or tendon repair, depending on the severity of the condition.
