2025 ICD-10-CM code M60

Myositis

Code M60 is a general code for myositis and should be used when a more specific type of myositis is not documented.If a more specific diagnosis is available (e.g., dermatomyositis, polymyositis), the more specific code should be used.

Medical necessity for testing and treatment should be supported by documentation of signs, symptoms, functional limitations, and the impact on the patient's quality of life.

Providers diagnose myositis based on physical examination, imaging studies (MRI), laboratory tests (muscle enzyme levels, erythrocyte sedimentation rate, autoantibodies), electromyography, and muscle biopsy. Treatment may include corticosteroids, NSAIDs, vitamins/supplements, lifestyle changes, and physical therapy.

In simple words: Myositis is when your muscles get inflamed, which means they swell up.This can happen because of an injury, an infection, or a problem with your body's defense system (autoimmune disease). It can make your muscles feel weak, tired, and painful.

Myositis is a general term for inflammation of the muscles.It can be caused by injury, infection, or autoimmune disease.

Example 1: A 45-year-old female presents with progressive muscle weakness in her hips and thighs, making it difficult to climb stairs and rise from a chair.After examination and testing (including elevated muscle enzymes and positive autoantibodies), she is diagnosed with polymyositis (M60)., A 65-year-old male experiences weakness in his hands and forearms, along with difficulty swallowing. He is diagnosed with inclusion body myositis (M60) after a muscle biopsy reveals characteristic protein deposits., A 30-year-old female presents with muscle pain, fatigue, and a distinctive rash on her face and knuckles.She is diagnosed with dermatomyositis (M60) after a skin biopsy confirms the diagnosis.

Documentation should include signs and symptoms, physical exam findings, results of laboratory and imaging studies (MRI, EMG, muscle biopsy), and any associated conditions.Detailed descriptions of muscle weakness and its impact on daily activities are crucial.

** Inclusion body myositis (IBM), though coded under M60, has different characteristics and treatment considerations compared to other forms of myositis. It's important to distinguish between the different types of myositis for accurate diagnosis and treatment planning.Refer to iFrameAI for more details if needed.
