Code Description

ICD-10 M05.511 is a billable code used to indicate a diagnosis of rheumatoid polyneuropathy with rheumatoid arthritis of right shoulder.

Key Diagnostic Point:

Rheumatoid polyneuropathy is a complication of rheumatoid arthritis (RA) characterized by peripheral nerve involvement due to systemic inflammation. The right shoulder, being a common site of RA, may exhibit synovitis, joint effusion, and erosive changes leading to pain and functional impairment. Anatomically, the shoulder comprises the glenohumeral joint, acromioclavicular joint, and surrounding musculature, which can be affected by inflammatory processes. Clinically, patients may present with weakness, sensory changes, and limited range of motion in the shoulder, alongside systemic symptoms of RA such as fatigue and morning stiffness. The pathophysiology involves immune-mediated damage to both joints and peripheral nerves, necessitating a comprehensive approach to management and coding.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Involvement of multiple body systems (musculoskeletal and nervous)
  • Need for precise documentation of joint involvement and laterality
  • Variability in clinical presentation and severity
  • Potential for overlapping symptoms with other conditions

Audit Risk Factors

  • Inadequate documentation of joint involvement and laterality
  • Failure to document the severity of symptoms
  • Misclassification of polyneuropathy as unrelated to RA
  • Lack of comprehensive functional assessments

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed imaging reports (X-rays, MRIs) showing joint damage, functional assessments documenting range of motion and strength.

Common Clinical Scenarios

Patients undergoing joint injections, arthroscopy, or joint replacement due to severe RA.

Billing Considerations

Documenting the extent of joint damage and any surgical interventions performed.

Rheumatology

Documentation Requirements

Lab results indicating inflammatory markers (e.g., ESR, CRP), disease activity scores (DAS28), and patient-reported outcomes.

Common Clinical Scenarios

Management of RA flares, initiation of DMARD therapy, or biologics.

Billing Considerations

Monitoring systemic involvement and adjusting treatment based on disease progression.

Physical Medicine

Documentation Requirements

Functional assessments including mobility evaluations, assistive device needs, and rehabilitation goals.

Common Clinical Scenarios

Rehabilitation post-surgery or during flare-ups to improve function and mobility.

Billing Considerations

Addressing mobility limitations and planning for assistive devices.

Coding Guidelines

Inclusion Criteria

Use M05.511 When
  • Coders must ensure accurate laterality (right shoulder), document the severity of the condition, and specify the encounter type (initial, follow
  • up, etc

Exclusion Criteria

Documentation Requirements

Specialty Considerations

Orthopedic documentation should include imaging findings and functional assessments.

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 progression and treatment outcomes.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of disease progression and treatment outcomes.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for greater specificity in coding musculoskeletal conditions, enabling better tracking of disease progression and treatment outcomes.
