What This Code Means

Rheumatoid arthritis without the typical blood marker affecting the right ankle and foot, causing joint inflammation and potential damage.

Coding Tips

  • This code is specific to the right side; use M06.072 for left side involvement
  • Document whether this is seronegative (RF negative) versus seropositive disease for accurate coding

Clinical Significance

Seronegative rheumatoid arthritis affecting right ankle and foot indicates systemic inflammatory disease with potential for joint destruction and functional impairment. This diagnosis supports risk adjustment for chronic autoimmune conditions requiring specialized care and immunosuppressive therapies.

Documentation Requirements

  • Established diagnosis of rheumatoid arthritis with physician documentation
  • Confirmed negative rheumatoid factor (RF) serology results
  • Specific documentation of right ankle and/or foot involvement
  • Clinical findings consistent with inflammatory arthritis
  • Evidence of synovitis, joint effusion, or inflammatory changes
  • Treatment with DMARDs, biologics, or other RA-specific therapies
  • Functional assessment including mobility and ambulation status
  • Exclusion of other inflammatory arthropathies
