Urethral disorders in diseases classified elsewhere (N37) ICD-10-CM
The N37 code range covers urethral disorders in diseases classified elsewhere with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- underlying disease
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the N37 Code Range
The ICD-10 code N37 is used specifically for urethral disorders that occur as a result of other underlying diseases classified elsewhere in the ICD-10 system. It captures cases where the urethra is affected in conjunction with a primary condition found in a different ICD-10 category.
Urethral disorders in diseases classified elsewhere (N37) serve as a code to document complications or secondary issues affecting the urethra caused by other medical conditions, rather than primary urethral disease. This code helps healthcare professionals and medical coders accurately represent and track urethral problems that arise due to systemic illness, injury, or other distinct disease processes. By identifying these urethral issues under N37, providers ensure precise coding for billing and clinical documentation when the primary disease is recorded under a different ICD-10 code. The use of ICD-10 code N37 ensures clarity in cases where the disorder is not isolated but linked to another recognized disease category.
