- •Document the specific condition in the medical record to support accurate coding
Clinical Significance
Other specified disorders of arteries and arterioles is a catch-all code for arterial conditions not classified elsewhere, such as fibromuscular dysplasia, arterial fibrodysplasia, or erosion of arteries. While less specific than individual disease codes, it still captures meaningful vascular disease for risk adjustment. Providers should be queried for more specific diagnoses when possible.

- ✓Diagnostic workup results supporting the arterial condition
- ✓Affected arteries identified when possible
- ✓Assessment of clinical impact and complications
