Code Description

ICD-10 M02.112 is a billable code used to indicate a diagnosis of postdysenteric arthropathy, left shoulder.

Key Diagnostic Point:

Postdysenteric arthropathy refers to a type of inflammatory arthritis that occurs following an episode of dysentery, typically caused by bacterial infections such as Shigella or Salmonella. The left shoulder joint, a ball-and-socket joint formed by the humerus and the scapula, can become involved in this condition, leading to pain, swelling, and reduced range of motion. Clinically, patients may present with acute or chronic shoulder pain, stiffness, and functional limitations in activities of daily living. The pathophysiology involves an autoimmune response triggered by the infection, leading to synovial inflammation and joint damage. Diagnosis is often supported by clinical examination, imaging studies, and laboratory tests to rule out other causes of arthritis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of post-infectious arthritis mechanisms
  • Involves specific anatomical knowledge of the shoulder joint
  • Differentiation from other types of arthritis is necessary
  • Documentation of laterality and specific joint involvement is critical

Audit Risk Factors

  • Inadequate documentation of the infectious history leading to arthropathy
  • Failure to specify laterality (left shoulder) in documentation
  • Misclassification of the type of arthritis
  • Lack of supporting imaging or lab results

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

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

Common Clinical Scenarios

Patients may present with acute shoulder pain post-dysentery, requiring evaluation for potential surgical intervention if conservative management fails.

Billing Considerations

Joint-specific considerations include assessing for rotator cuff involvement and the severity of synovitis.

Rheumatology

Documentation Requirements

Rheumatologic documentation should include inflammatory markers (ESR, CRP) and assessments of disease activity (e.g., joint counts).

Common Clinical Scenarios

Patients may have a history of gastrointestinal infections leading to inflammatory arthritis, necessitating a comprehensive evaluation of systemic involvement.

Billing Considerations

Consideration of other autoimmune conditions that may coexist and affect treatment plans.

Physical Medicine

Documentation Requirements

Functional assessments should document the patient's ability to perform daily activities and any assistive devices used.

Common Clinical Scenarios

Rehabilitation scenarios may include post-surgical recovery or conservative management of shoulder pain.

Billing Considerations

Focus on mobility limitations and the need for tailored rehabilitation programs.

Coding Guidelines

Inclusion Criteria

Use M02.112 When
  • Follow official coding guidelines for laterality, ensuring the left shoulder is specified
  • Document the severity of the condition and the type of encounter (initial, follow
  • up, etc

Exclusion Criteria

Do NOT use M02.112 When
No specific exclusions found.

20610CPT Code

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

Clinical Scenario

Used for therapeutic aspiration of the shoulder joint in cases of effusion.

Documentation Requirements

Document the indication for the procedure, including joint effusion and pain severity.

Specialty Considerations

Orthopedic considerations include assessing the need for imaging prior to the 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 post-infectious arthropathies and their management.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of post-infectious arthropathies and their management.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of post-infectious arthropathies and their management.
