Billable/Specific Code

N05.A is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
The 2023 edition of ICD-10-CM N05.A became effective on October 1, 2022.
This is the American ICD-10-CM version of N05.A - other international versions of ICD-10 N05.A may differ.

Unspecified nephritic syndrome with C3 glomerulopathy

Type 1 Excludes

Type 1 Excludes Help

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as N05.A. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
