This is the American ICD-10-CM version of E52 - other international versions of ICD-10 E52 may differ.

Applicable To

Niacin (-tryptophan) deficiency
Nicotinamide deficiency
Pellagra (alcoholic)

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 E52. 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.
