R35.0

Frequency of micturition

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R35.0 is a billable code used to indicate a diagnosis of frequency of micturition.

Key Diagnostic Point:

Frequency of micturition refers to the increased number of times a person urinates within a given time frame, which can be a symptom of various underlying conditions. This symptom can be classified as either nocturia (urination at night) or diurnal frequency (urination during the day). It may be associated with conditions such as urinary tract infections (UTIs), diabetes mellitus, bladder irritability, prostate disorders in men, and certain neurological conditions. Patients may report a sense of urgency or discomfort, and the frequency can disrupt daily activities and sleep patterns. A thorough clinical evaluation is necessary to determine the underlying cause, which may include a detailed patient history, physical examination, urinalysis, and possibly imaging studies. Understanding the context of increased micturition is crucial for appropriate management and treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes that can lead to increased frequency of micturition.
  • Need for comprehensive patient history to determine the context of the symptom.
  • Potential overlap with other urinary symptoms, complicating diagnosis.
  • Documentation requirements vary significantly across specialties.

Audit Risk Factors

  • Inadequate documentation of patient history and symptom duration.
  • Failure to specify associated symptoms or conditions.
  • Misclassification of frequency as urgency or incontinence.
  • Lack of supporting diagnostic tests in the medical record.
