Code Description

ICD-10 M02.851 is a billable code used to indicate a diagnosis of other reactive arthropathies, right hip.

Key Diagnostic Point:

Reactive arthropathies are inflammatory joint conditions that arise secondary to infections or other systemic diseases. The right hip joint, a ball-and-socket joint formed by the femur and the acetabulum of the pelvis, is susceptible to these conditions. Clinically, patients may present with pain, swelling, and reduced range of motion in the right hip. The pathophysiology often involves an immune response triggered by an infection elsewhere in the body, leading to synovial inflammation and joint damage. Patients may experience stiffness, particularly after periods of inactivity, and may have difficulty with weight-bearing activities. The hip joint's anatomical complexity, including surrounding muscles, ligaments, and tendons, contributes to the functional limitations observed in affected individuals. Diagnosis typically involves clinical evaluation, imaging studies, and laboratory tests to rule out other causes of arthritis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Anatomical specificity of the hip joint
  • Differentiation from other arthropathies
  • Need for comprehensive clinical documentation
  • Potential for systemic involvement

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify laterality
  • Misclassification of reactive versus degenerative conditions
  • Lack of supporting imaging or lab results

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Orthopedic documentation should include imaging results (X-rays, MRIs) and functional assessments (range of motion, strength testing).

Common Clinical Scenarios

Patients may present with acute hip 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 soft tissue injuries is crucial for treatment planning.

Rheumatology

Documentation Requirements

Rheumatologic documentation must include inflammation markers (ESR, CRP) and assessments of disease activity (e.g., DAS28).

Common Clinical Scenarios

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

Billing Considerations

Consideration of systemic involvement and potential for chronicity is essential in managing these patients.

Physical Medicine

Documentation Requirements

Functional assessments should evaluate mobility, pain levels, and rehabilitation needs, including assistive devices.

Common Clinical Scenarios

Patients may require rehabilitation post-infection or after joint injections to restore function.

Billing Considerations

Focus on mobility limitations and the impact on daily activities is critical for effective treatment planning.

Coding Guidelines

Inclusion Criteria

Use M02.851 When
  • Follow official coding guidelines for laterality, ensuring the right hip is specified
  • Document the severity of the condition and the type of encounter (initial, follow
  • up, etc
  • ) to support the coding

Exclusion Criteria

Do NOT use M02.851 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?

Common causes include infections (e.g., gastrointestinal, genitourinary), autoimmune diseases, and post-infectious inflammatory responses. Understanding the underlying cause is crucial for effective management.
