Code Description

ICD-10 M02.812 is a billable code used to indicate a diagnosis of other reactive arthropathies, left shoulder.

Key Diagnostic Point:

Reactive arthropathies are inflammatory joint conditions that arise secondary to infections or other systemic diseases, often presenting with joint pain, swelling, and stiffness. The left shoulder, comprising the glenohumeral joint, acromioclavicular joint, and scapulothoracic articulation, can be affected by these arthropathies. Clinically, patients may exhibit limited range of motion, tenderness, and signs of inflammation. Pathophysiologically, these conditions may involve immune-mediated responses triggered by infections elsewhere in the body, leading to synovial inflammation and joint damage. Common presentations include pain exacerbated by movement, particularly overhead activities, and may be associated with systemic symptoms such as fever or malaise. Diagnosis typically involves clinical evaluation, imaging studies, and laboratory tests to rule out other causes of shoulder pain.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for accurate laterality documentation
  • Differentiation from other arthropathies
  • Potential overlap with systemic conditions
  • Variability in clinical presentation

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify laterality
  • Misclassification of the type of arthropathy
  • Lack of supporting imaging or lab results

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Orthopedic documentation should include imaging results (e.g., X-rays, MRI) and functional assessments of the shoulder's range of motion.

Common Clinical Scenarios

Patients may present with acute shoulder pain following a recent infection or systemic illness, requiring surgical intervention if conservative management fails.

Billing Considerations

Documenting the severity of joint involvement and any associated rotator cuff pathology is crucial for accurate coding.

Rheumatology

Documentation Requirements

Rheumatologic documentation should include inflammatory markers (e.g., ESR, CRP) and assessments of disease activity.

Common Clinical Scenarios

Patients may have a history of autoimmune conditions that predispose them to reactive arthropathies, necessitating a comprehensive evaluation.

Billing Considerations

Systemic involvement, such as skin or mucosal lesions, should be documented to support the diagnosis.

Physical Medicine

Documentation Requirements

Functional assessments should evaluate the patient's ability to perform daily activities and any rehabilitation needs.

Common Clinical Scenarios

Patients may require physical therapy to restore shoulder function and mobility following an episode of reactive arthritis.

Billing Considerations

Documenting mobility limitations and the need for assistive devices is essential for comprehensive care.

Coding Guidelines

Inclusion Criteria

Use M02.812 When
  • 10 coding guidelines require specificity in laterality (left shoulder) and the nature of the arthropathy
  • Documentation must reflect the encounter type (initial, follow
  • up) and any relevant comorbidities

Exclusion Criteria

Do NOT use M02.812 When
No specific exclusions found.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of reactive arthropathies and their management.

Frequently Asked Questions

What are the common causes of reactive arthropathies?

Reactive arthropathies can be triggered by infections, such as gastrointestinal or genitourinary infections, and may also be associated with autoimmune conditions. The immune response to these infections can lead to joint inflammation and pain.
