Code Description

ICD-10 M02.341 is a billable code used to indicate a diagnosis of reiter's disease, right hand.

Key Diagnostic Point:

Reiter's disease, also known as reactive arthritis, is a type of inflammatory arthritis that develops in response to an infection in another part of the body. It is characterized by the classic triad of arthritis, urethritis, and conjunctivitis. In the context of the right hand, the disease typically manifests as inflammation of the joints, particularly affecting the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. Anatomically, the right hand consists of 27 bones, including the carpals, metacarpals, and phalanges, which can become swollen and painful due to the inflammatory process. The pathophysiology involves an autoimmune response triggered by infections, often involving the urogenital or gastrointestinal tracts. Clinically, patients may present with joint pain, stiffness, and swelling, particularly after a recent infection. Movement limitations may include difficulty in gripping or performing fine motor tasks, impacting daily activities. Early diagnosis and management are crucial to prevent chronic joint damage.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of autoimmune mechanisms and joint anatomy.
  • Involves multiple systems (musculoskeletal and systemic).
  • Documentation must specify laterality and joint involvement.
  • Differentiation from other types of arthritis is necessary.

Audit Risk Factors

  • Inadequate documentation of joint involvement and laterality.
  • Failure to document prior infections that may relate to the condition.
  • Misclassification of Reiter's disease as another type of arthritis.
  • Lack of evidence for functional limitations impacting daily activities.

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

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

Common Clinical Scenarios

Patients may present with acute pain and swelling in the right hand, requiring joint aspiration or corticosteroid injections.

Billing Considerations

Documentation must detail the specific joints involved and any surgical interventions considered.

Rheumatology

Documentation Requirements

Rheumatologic documentation should include laboratory tests for inflammatory markers (ESR, CRP) and disease activity scores to monitor progression.

Common Clinical Scenarios

Patients may have a history of recent infections, presenting with systemic symptoms alongside joint pain.

Billing Considerations

Consideration of systemic involvement, such as skin lesions or ocular symptoms, is essential for comprehensive care.

Physical Medicine

Documentation Requirements

Functional assessments should evaluate mobility, strength, and the need for assistive devices to aid in rehabilitation.

Common Clinical Scenarios

Patients may require physical therapy to improve hand function and reduce pain.

Billing Considerations

Focus on mobility limitations and the impact on activities of daily living is crucial.

Coding Guidelines

Inclusion Criteria

Use M02.341 When
  • 10 coding guidelines require specificity in laterality (right hand) and the severity of the condition
  • Documentation must reflect the encounter type (initial, follow
  • up) and any relevant comorbidities

Exclusion Criteria

Do NOT use M02.341 When
No specific exclusions found.

Clinical Scenario

Used when a patient with Reiter's disease presents with significant joint effusion in the right hand.

Documentation Requirements

Document the joint aspirated, the amount of fluid removed, and any therapeutic agents injected.

Specialty Considerations

Orthopedic and rheumatologic considerations for joint management.

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.
