    ICD-10-CM Code For Other Crystal Arthropathies: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M11 includes diagnoses for crystal-induced arthropathies other than gout, such as calcium pyrophosphate deposition disease and other specified crystal deposition disorders affecting joints and periarticular structures. These ICD-10-CM diagnosis codes are used to document clinical presentations of acute or chronic crystal-associated arthritis, capturing disease distribution, joint involvement, and complications like inflammatory flares or joint damage. Accurate coding within the ICD-10-CM M11 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM M11: Other Crystal Arthropathies Overview

    The diagnoses in this group represent disorders caused by deposition of crystals in joints and periarticular tissues, such as calcium pyrophosphate deposition disease and other less common crystal arthropathies. These conditions affect the musculoskeletal system, particularly joints, and can cause acute or chronic inflammatory arthritis. Accurate coding is important for correct clinical documentation and for reimbursement by payers including the Centers for Medicare & Medicaid Services.

    When to Use

    Use a code from this group when clinical evaluation, imaging, or synovial fluid analysis indicates crystal deposition disease other than gout in a specific joint or region. Apply the most specific code available to reflect the affected joint(s), laterality when required, and any acute flare or chronic sequelae.
