What This Code Means

Rheumatoid arthritis without the typical blood marker affecting multiple joints throughout the body simultaneously.

Coding Tips

  • Use this code when three or more different joint sites are involved; document all affected areas
  • Consider if more specific codes for individual sites would be more appropriate for billing and clinical tracking

Clinical Significance

Seronegative rheumatoid arthritis affecting multiple sites indicates systemic disease with polyarticular involvement requiring aggressive treatment and monitoring. This diagnosis represents the most severe form of RA with significant functional impact and healthcare resource utilization.

Documentation Requirements

  • Confirmed rheumatoid arthritis diagnosis with multiple joint involvement
  • Laboratory confirmation of negative rheumatoid factor
  • Documentation of at least 3 or more affected joint regions
  • Clinical evidence of symmetric or asymmetric polyarthritis
  • Assessment of disease activity using standardized measures
  • Treatment with systemic DMARDs or biologic agents
  • Functional assessment and disability evaluation
  • Documentation of chronicity and ongoing management needs
