Code Description

ICD-10 M02.331 is a billable code used to indicate a diagnosis of reiter's disease, right wrist.

Key Diagnostic Point:

Reiter's disease, also known as reactive arthritis, is an inflammatory condition that typically arises following an infection, most commonly in the urogenital or gastrointestinal tract. It is characterized by a triad of symptoms: arthritis, urethritis, and conjunctivitis. In the case of M02.331, the focus is on the right wrist joint, which may exhibit swelling, pain, and stiffness due to inflammation. Anatomically, the wrist consists of the distal radius and ulna, along with the carpal bones, which articulate with the metacarpals. The inflammatory process in Reiter's disease can lead to synovitis, affecting the joint capsule and surrounding soft tissues, resulting in decreased range of motion and functional impairment. Clinically, patients may present with acute onset of pain and swelling in the wrist, often accompanied by systemic symptoms such as fever and malaise. The pathophysiology involves an autoimmune response triggered by the initial infection, leading to the deposition of immune complexes in the joints, particularly affecting the lower extremities but can also involve the upper extremities, including the wrist.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of autoimmune mechanisms and joint anatomy
  • Differentiation from other types of arthritis
  • Documentation of laterality and specific joint involvement
  • Potential for systemic manifestations affecting coding

Audit Risk Factors

  • Inadequate documentation of the inflammatory process
  • Failure to specify laterality or joint involvement
  • Misclassification of Reiter's disease as another type of arthritis
  • Lack of supporting evidence for systemic symptoms

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

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

Common Clinical Scenarios

Patients may require surgical intervention for severe joint damage or persistent symptoms unresponsive to conservative management.

Billing Considerations

Orthopedic considerations include the assessment of joint stability and the potential for surgical repair or joint replacement.

Rheumatology

Documentation Requirements

Rheumatologic documentation must include laboratory tests for inflammatory markers (e.g., ESR, CRP) and assessments of disease activity using validated scales.

Common Clinical Scenarios

Patients may present with exacerbations of arthritis following infections, requiring adjustments in treatment regimens.

Billing Considerations

Systemic involvement, such as skin lesions or ocular symptoms, should be documented to provide a comprehensive view of the disease.

Physical Medicine

Documentation Requirements

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

Common Clinical Scenarios

Rehabilitation may focus on restoring function and managing pain through physical therapy and occupational therapy.

Billing Considerations

Mobility limitations should be documented to tailor rehabilitation programs effectively.

Coding Guidelines

Inclusion Criteria

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has increased specificity in coding musculoskeletal conditions, allowing for better tracking of disease prevalence and treatment outcomes. M02.331 provides a clear indication of the affected joint and laterality, improving clinical data accuracy.

ICD-9 vs ICD-10

The transition to ICD-10 has increased specificity in coding musculoskeletal conditions, allowing for better tracking of disease prevalence and treatment outcomes. M02.331 provides a clear indication of the affected joint and laterality, improving clinical data accuracy.

Reimbursement & Billing Impact
