    ICD-10-CM Code For Other Rheumatoid Arthritis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M06 includes seronegative and other specified rheumatoid arthritis diagnoses that capture inflammatory polyarthropathies not classified as seropositive rheumatoid arthritis. These ICD-10-CM diagnosis codes are used to document clinical presentations of inflammatory joint disease, capturing disease distribution, severity, and any extra-articular involvement relevant to patient management. Accurate coding within the ICD-10-CM M06 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM M06: Other Rheumatoid Arthritis Overview

    This group includes rheumatoid arthritis variants that do not meet criteria for seropositive rheumatoid arthritis, encompassing seronegative and other specified rheumatoid arthritides affecting joints and periarticular structures. These conditions target the musculoskeletal system with inflammatory polyarthritis and can involve multiple joints, functional impairment, and extra-articular features. Accurate coding matters for appropriate claim adjudication and to reflect clinical complexity that influences care and reimbursement.

    When to Use

    Use a code from this group when clinical documentation identifies rheumatoid arthritis that is seronegative or specified as other rheumatoid arthritis rather than seropositive disease. Codes apply when the clinician documents inflammatory joint involvement, distribution, and any related systemic features relevant to the episode of care.

    Typical Clinical Scenarios

    • A middle-aged patient with a several-year history of seronegative inflammatory polyarthritis presents to the rheumatology clinic with progressive morning stiffness, symmetric swelling of multiple small hand joints and new erosive changes on radiographs despite DMARD therapy; the visit documents chronic, established disease activity without current infection or recent joint replacement, so an other rheumatoid arthritis code denoting chronic polyarticular involvement is assigned. Typical codes: M06.0A, M06.1
    • An older adult is seen in the emergency department for acute-on-chronic worsening of joint pain, warmth and limited range of motion in multiple large and small joints consistent with an inflammatory flare; after infection and crystal arthritis are excluded, the clinician records an acute exacerbation of previously diagnosed seronegative rheumatoid-like polyarthritis, leading to use of an acute/flare-related code from this group. Typical codes: M06.20, M06.30
    • A young adult with long-standing inflammatory polyarthritis is evaluated for systemic complications including rheumatoid nodules and documented interstitial lung disease as a comorbidity; the visit focuses on managing extraarticular manifestations and chronic polyarthropathy is coded to capture the underlying inflammatory joint disorder contributing to these complications. Typical codes: M06.4, M06.8A
