ICD-10 Code G72.2 – Myopathy due to other toxic agents (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G72.2 – Myopathy due to other toxic agents
What it is
G72.2 identifies a toxic myopathy caused by exposure to agents other than alcohol or statins. Use it when documentation links muscle weakness or injury to a specific toxic exposure.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include muscle weakness, muscle pain, or elevated suspicion of toxin-related muscle injury after exposure history supports the diagnosis.
When to use this code
Use this code when the provider documents myopathy due to a toxic agent and does not assign a more specific code. It fits cases where the record identifies a medication, chemical, or other toxin as the cause. If the cause is unclear, check documentation before coding.
Do not use for
Do not use G72.2 for myopathy clearly caused by alcohol or statins, since those conditions have separate coding pathways. Also avoid it when only generalized weakness is documented without a confirmed toxic myopathy.
Coding tip
Code the toxic cause only when the record clearly links the myopathy to the exposure; otherwise, verify the diagnosis and etiology in the note.
