M62: ICD10 Code for Other disorders of muscle

M62 refers to Other disorders of muscle, covering inflammatory, degenerative, and pathological conditions affecting skeletal muscle tissue. These disorders can cause muscle pain, weakness, reduced mobility, and long-term functional limitations if untreated.

Symptoms

• Muscle weakness – Primary symptom of myositis (M60) and other muscle disorders
• Muscle pain (myalgia) – Seen in inflammatory and metabolic myopathies (M62)
• Hard nodules or stiffness – Indicative of calcification/ossification (M61)
• Difficulty climbing stairs or lifting arms – Typical functional deficits
• Fatigue and systemic symptoms – Associated with inflammatory myopathies

Diagnosis

Diagnosis of Other disorders of muscle includes clinical evaluation, serum creatine kinase (CK) levels, electromyography (EMG), MRI to detect muscle edema or fibrosis, and sometimes muscle biopsy to confirm inflammation, degeneration, or abnormal calcification.

ICD10 Code Usage

ICD10 code M62 is used by rheumatologists, neurologists, orthopedic specialists, and rehabilitation teams to document muscle disorders for medical records, insurance claims, and treatment planning including immunosuppressive therapies or physical rehabilitation.

Related Codes

• M60 – Myositis
• M61 – Calcification and ossification of muscle
• M63 – Disorders of muscle in diseases classified elsewhere

FAQs

Q1: What is ICD10 code M62?
A: It refers to Other disorders of muscle, encompassing inflammatory, degenerative, and systemic muscle disorders that impair mobility and strength.

Q2: What is myositis (M60)?
A: Inflammatory conditions of muscle tissue, including polymyositis and dermatomyositis, leading to muscle weakness and systemic symptoms.

Q3: What causes muscle calcification (M61)?
A: It can result from trauma, chronic inflammation, metabolic disturbances, or post-surgical changes, leading to hardening of muscles.

Q4: What are examples of M62 muscle disorders?
A: Muscle contractures, myopathies due to endocrine disorders, and other acquired or hereditary muscle dysfunctions.

Q5: Who typically treats muscle disorders?
A: Rheumatologists, neurologists, orthopedic specialists, and physiatrists (rehabilitation doctors).

Conclusion

ICD10 code M62 is essential for accurate classification and treatment of Other disorders of muscle, helping guide targeted therapies to improve muscle strength, function, and overall patient mobility.
