N06: Isolated proteinuria with specified morphological lesion
Non-billable headerICD-10-CM
N06 is a non-billable header ICD-10-CM code for isolated proteinuria with specified morphological lesion. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1: never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- Proteinuria not associated with specific morphologic lesions (R80.0)
Other codes that can never be billed with N06
Their own Excludes1 notes name this code, so the conflict is not listed above.
Risk adjustment
No CMS-HCC V28 category: this code does not change a RAF score.
Code history
Unchanged in every release from FY2024 to FY2027.
