R35 is a non-billable ICD-10-CM category code for polyuria, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R35.0, R35.1, R35.81, and R35.89. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Code First
- , if applicable, any causal condition, such as:
- enlarged prostate N40.1
Type 1 Excludes
- psychogenic polyuria F45.8
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.
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.

Patient EducationClinical
Urine and Urination
Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate.

Questions About R35Overview
Is R35 (Polyuria) a billable code?
No. This is a category header that groups the codes for polyuria, and headers cannot be submitted on claims. Claims for polyuria need a more specific code from this category, such as R35.0, R35.1, and R35.81.
Can R35 be a principal diagnosis?
Use it with care. This is a symptom code, so once a definitive diagnosis explaining the polyuria is established, that condition takes the principal position instead.
