    ICD-10-CM Code For Polyosteoarthritis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M15 includes diagnoses for polyosteoarthritis and related generalized osteoarthritic conditions affecting multiple joints, such as primary generalized osteoarthritis and secondary polyosteoarthritis. These ICD-10-CM diagnosis codes are used to document the presence of degenerative joint disease involving several joint sites, capturing disease distribution, joint involvement, and clinical complexity relevant to this group. Accurate coding within the ICD-10-CM M15 group supports complete clinical documentation and appropriate reimbursement.

    ICD-10-CM M15: Polyosteoarthritis Overview

    The ICD-10-CM M15 group represents polyosteoarthritis, a form of degenerative joint disease affecting multiple joints. These diagnoses target the musculoskeletal system and describe generalized osteoarthritic changes across several joint sites. Accurate coding matters for complete clinical documentation and appropriate reimbursement by reflecting disease distribution and severity.

    When to Use

    Use a code from this group when documentation indicates osteoarthritis involving multiple joints or generalized osteoarthritis rather than a single joint site. Select the specific code that reflects primary versus secondary polyosteoarthritis and any documented laterality or complications.

    Typical Clinical Scenarios

    • An older patient with progressively worsening joint pain and stiffness over several years involving multiple joint sites (hands with Heberden nodes, base of thumbs, bilateral hips and knees) presents for routine follow-up and management of chronic degenerative joint disease causing functional limitation; physical exam shows crepitus and reduced range of motion in multiple joints and radiographs confirm degenerative changes in several articular sites. A polyarticular osteoarthritis diagnosis from this group is assigned to capture generalized degenerative involvement. Typical codes: M15.0, M15.1
    • A middle-aged adult with long-standing rheumatoid disease history now primarily experiencing symmetric degenerative changes and pain in multiple large joints without signs of active inflammatory synovitis presents to orthopedics for assessment of surgical candidacy; imaging demonstrates advanced osteoarthritic change in bilateral hips and knees consistent with secondary polyarticular osteoarthritis. A code from this group is used to indicate polyosteoarthritic involvement as a comorbid structural condition affecting treatment planning. Typical codes: M15.2, M15.3
    • An elderly patient admitted after a fall who is noted to have chronic widespread degenerative joint disease contributing to impaired mobility and difficulty with activities of daily living; the polyarticular osteoarthritic condition is documented as a significant chronic comorbidity that affects rehabilitation needs and discharge planning during the acute hospitalization. A diagnosis from this group is assigned to reflect multi-joint osteoarthritic disease as a comorbidity. Typical codes: M15.4, M15.9
