Code Description

ICD-10 M02.351 is a billable code used to indicate a diagnosis of reiter's disease, right hip.

Key Diagnostic Point:

Reiter's disease, also known as reactive arthritis, is a type of inflammatory arthritis that occurs as a reaction to an infection in another part of the body. It is characterized by the classic triad of arthritis, urethritis, and conjunctivitis. In the case of M02.351, the inflammation specifically affects the right hip joint. Anatomically, the hip joint is a ball-and-socket joint formed by the acetabulum of the pelvis and the head of the femur, allowing for a wide range of motion. Pathophysiologically, Reiter's disease is believed to be triggered by an autoimmune response following infections, commonly involving the genitourinary or gastrointestinal systems. Clinically, patients may present with pain, swelling, and stiffness in the right hip, which can lead to significant movement limitations and functional impairment. The condition may also involve other joints and can be associated with enthesitis and dactylitis. Early diagnosis and management are crucial to prevent chronic joint damage and disability.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of autoimmune mechanisms and joint pathology
  • Involves specific anatomical localization (right hip)
  • Differentiation from other types of arthritis
  • Potential for systemic involvement affecting coding

Audit Risk Factors

  • Inadequate documentation of joint involvement and severity
  • Failure to document prior infections that may have triggered the condition
  • Misclassification of Reiter's disease as another type of arthritis
  • Lack of evidence for functional limitations in the documentation

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint damage, range of motion assessments, and functional evaluations.

Common Clinical Scenarios

Common scenarios include surgical interventions for joint repair or replacement in advanced cases, as well as conservative management strategies.

Billing Considerations

Joint-specific considerations include the assessment of joint stability, alignment, and the presence of effusion or synovitis.

Rheumatology

Documentation Requirements

Rheumatologic documentation must include laboratory tests for inflammatory markers (ESR, CRP), HLA-B27 testing, and assessments of disease activity.

Common Clinical Scenarios

Autoimmune scenarios may involve managing systemic symptoms and coordinating care with other specialists.

Billing Considerations

Consideration of systemic involvement, such as skin or eye symptoms, is crucial for comprehensive management.

Physical Medicine

Documentation Requirements

Functional assessments should document mobility limitations, pain levels, and the need for assistive devices.

Common Clinical Scenarios

Rehabilitation scenarios may include physical therapy for joint mobility and strength training.

Billing Considerations

Focus on improving functional outcomes and quality of life for patients with mobility impairments.

Coding Guidelines

Inclusion Criteria

Use M02.351 When
  • 10 coding guidelines for M02
  • 351 require accurate documentation of laterality (right hip) and the severity of the condition
  • Encounter type (initial, subsequent, or sequela) must also be documented appropriately

Exclusion Criteria

20610CPT Code

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

Clinical Scenario

Used for joint aspiration in cases of effusion or injection of corticosteroids for inflammation.

Documentation Requirements

Documentation must include the indication for the procedure, joint involved, and any imaging guidance used.

Specialty Considerations

Orthopedic and rheumatologic considerations include the need for follow-up assessments post-procedure.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of disease prevalence and treatment outcomes. M02.351 provides a clear indication of the affected joint and the underlying condition.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of disease prevalence and treatment outcomes. M02.351 provides a clear indication of the affected joint and the underlying condition.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of disease prevalence and treatment outcomes. M02.351 provides a clear indication of the affected joint and the underlying condition.
