    ICD-10-CM Code For Postinfective And Reactive Arthropathies: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M02 includes arthropathies that arise after or in response to an infection, such as reactive arthritis and other postinfectious joint inflammations. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving inflammatory joint pain and swelling linked to prior or concurrent infections, capturing disease distribution, affected joints, and any systemic involvement. Accurate coding within the ICD-10-CM M02 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM M02: Postinfective And Reactive Arthropathies Overview

    The ICD-10-CM M02 group covers postinfective and reactive arthropathies, inflammatory joint disorders that follow or are associated with infectious triggers. These conditions primarily affect the musculoskeletal system, particularly joints and adjacent structures. Accurate coding matters for clinical continuity and reimbursement because it documents the infectious association and directs appropriate claim adjudication.

    When to Use

    Use a code from the ICD-10-CM M02 group when a clinician documents arthritis as a consequence of or in reaction to a documented or suspected infection. Select the specific code that reflects the joint involvement and any identified infectious agent to accurately represent the clinical encounter.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden onset of a swollen, warm, and painful knee three days after a documented episode of bacterial gastroenteritis; joint aspiration shows sterile inflammatory fluid and cultures are negative, suggesting a postinfectious reactive arthritis affecting a single large joint. A diagnosis from this group is assigned because the arthritis began following an identifiable infectious trigger and there is clinical and laboratory evidence of a reactive, nonseptic inflammatory arthropathy. Typical codes: M02.069, M02.079
    • A young adult with recent urethritis develops symmetric pain and swelling of both ankles and several small joints of the feet over the course of two weeks, with enthesitis and conjunctivitis noted on exam; the patient is managed in outpatient rheumatology for ongoing reactive arthropathy. A code from this group is used to capture the chronic or subacute postinfective arthropathy linked to a genitourinary infection and multisite joint involvement. Typical codes: M02.271, M02.279
    • An elderly patient with diabetes is admitted for worsening mobility due to polyarticular inflammatory arthritis that began after a recent respiratory infection; concern for systemic involvement and need to differentiate from septic arthritis and underlying osteoarthritis leads to assignment of a postinfective/reactive arthropathy code as a comorbid contributor to the admission. Typical codes: M02.80, M02.819}
