Code Description

ICD-10 M02.352 is a billable code used to indicate a diagnosis of reiter's disease, left hip.

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 case of M02.352, the left hip joint is specifically affected. Anatomically, the hip joint is a ball-and-socket joint formed by the acetabulum of the pelvis and the head of the femur. The inflammation in Reiter's disease can lead to synovitis, which causes pain, swelling, and stiffness in the affected joint. Clinically, patients may present with unilateral hip pain, reduced range of motion, and tenderness upon palpation. The pathophysiology involves an autoimmune response triggered by infections, often of the urogenital or gastrointestinal tract, leading to inflammation in the joints, particularly in the lower extremities. 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 anatomy.
  • Differentiation from other types of arthritis is necessary.
  • Documentation of laterality and specific joint involvement is critical.
  • Potential for systemic involvement complicates coding.

Audit Risk Factors

  • Inadequate documentation of joint involvement and laterality.
  • Failure to document the underlying infection that triggered the arthritis.
  • Misclassification of Reiter's disease as another type of arthritis.
  • Lack of evidence for the severity of the condition.

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

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

Common Clinical Scenarios

Common scenarios include surgical interventions for severe joint damage or arthroplasty in chronic cases.

Billing Considerations

Joint-specific considerations include the need to document any deformities or functional limitations resulting from the disease.

Rheumatology

Documentation Requirements

Rheumatologic documentation must include laboratory tests for inflammatory markers (e.g., ESR, CRP) and assessments of disease activity (e.g., patient-reported outcomes).

Common Clinical Scenarios

Autoimmune and inflammatory scenarios often involve managing flare-ups and long-term disease management strategies.

Billing Considerations

Systemic involvement, such as ocular or genitourinary symptoms, should be documented to reflect the full impact of the disease.

Physical Medicine

Documentation Requirements

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

Common Clinical Scenarios

Rehabilitation scenarios may include physical therapy to restore function and mobility post-flare.

Billing Considerations

Mobility limitations should be documented to justify rehabilitation services and assistive device prescriptions.

Coding Guidelines

Inclusion Criteria

Use M02.352 When
  • According to official coding guidelines, coders must ensure accurate documentation of laterality (left hip), severity of the condition, and the type of encounter (initial, follow
  • up, etc
  • It is essential to capture the full clinical picture to support the diagnosis

Exclusion Criteria

Clinical Scenario

Used for therapeutic drainage or injection of corticosteroids in the left hip joint.

Documentation Requirements

Document the indication for the procedure, including joint involvement and any imaging findings.

Specialty Considerations

Orthopedic considerations include the need for imaging guidance in some cases.

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, including Reiter's disease. Coders can now capture laterality and specific joint involvement, which enhances the accuracy of patient records and treatment plans.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, including Reiter's disease. Coders can now capture laterality and specific joint involvement, which enhances the accuracy of patient records and treatment plans.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, including Reiter's disease. Coders can now capture laterality and specific joint involvement, which enhances the accuracy of patient records and treatment plans.
