    ICD-10-CM Code For Juvenile Arthritis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M08 includes juvenile arthritis diagnoses such as juvenile idiopathic arthritis subtypes and related inflammatory polyarthropathies affecting children and adolescents. These ICD-10-CM diagnosis codes are used to document clinical presentations including oligoarticular, polyarticular, and systemic involvement, capturing disease severity, joint involvement, and extraarticular manifestations. Accurate coding within the ICD-10-CM M08 group supports proper claim adjudication and complete clinical documentation.

    ICD-10-CM M08: Juvenile Arthritis Overview

    The ICD-10-CM M08 group captures juvenile arthritis diagnoses, including juvenile idiopathic arthritis subtypes and related inflammatory arthropathies occurring in children and adolescents. These conditions target the musculoskeletal system and may involve joints, periarticular structures, and systemic features. Accurate coding is important for clinical continuity and supports appropriate reimbursement and resource allocation.

    When to Use

    Use a code from this group when documenting a confirmed diagnosis of juvenile arthritis or a related inflammatory arthropathy in a pediatric patient. Codes should be selected to reflect the pattern of joint involvement and any systemic manifestations documented in the clinical record.

    Typical Clinical Scenarios

    • A 9-year-old child with a several-month history of morning stiffness, persistent swelling of multiple small and large joints (both wrists and knees), and limited range of motion presents to pediatric rheumatology for evaluation after poor response to NSAIDs. Examination shows synovitis in multiple joints and laboratory tests show elevated inflammatory markers; a chronic juvenile idiopathic polyarthritis diagnosis is made to guide long‑term disease‑directed management. Typical codes: M08.20, M08.21
    • A 6-year-old girl is brought to the emergency department with acute onset high fever, rash, and new-onset bilateral knee and ankle swelling causing inability to ambulate; clinicians suspect systemic juvenile arthritis flare with systemic features requiring inpatient treatment. Because the presentation is an acute systemic inflammatory exacerbation of juvenile arthritis involving multiple joints and systemic symptoms, an appropriate code from this group reflecting systemic juvenile arthritis with acute involvement is assigned. Typical codes: M08.00, M08.011
    • A 14-year-old adolescent with a long-standing history of juvenile-onset polyarthritis is seen in clinic for progressive joint deformities and chronic pain; she also has secondary uveitis documented by ophthalmology and decreased functional status. The visit documents chronic juvenile arthritis as the underlying cause of joint damage and extraarticular complication, so a chronic juvenile arthritis code is used to capture the primary disease contributing to musculoskeletal and ophthalmologic comorbidity. Typical codes: M08.40, M08.41
