A weakened, bulging section of an artery at an unspecified location in the body.
Coding Tips
- •This is a non-specific code; attempt to obtain more information about the aneurysm location from the provider
- •Query the physician if the specific artery location can be determined from imaging or clinical documentation
Clinical Significance
Aneurysm of unspecified site represents an aneurysmal condition where the specific artery has not been documented. While this captures vascular disease for risk adjustment, it is a nonspecific code that should prompt a review of available imaging and clinical documentation to assign a more precise code. The presence of any aneurysm indicates underlying vascular pathology requiring management.
Documentation Requirements
- ✓Documentation confirming aneurysm diagnosis
- ✓Any available imaging reports to determine specific location
- ✓Query provider for specific artery involved
- ✓Assessment of aneurysm status (intact, symptomatic, or complicated)
- ✓Treatment and surveillance plan
- ✓Underlying etiology when known
