    ICD-10-CM Code For Polyuria: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group R35 includes diagnoses for excessive urination and increased urine output, covering conditions such as polyuria due to endocrine disorders, renal causes, and unspecified polyuria. These ICD-10-CM diagnosis codes are used to document clinical presentations of increased urine volume or frequency, capturing disease severity, organ involvement, or clinical complexity relevant to this group. Accurate coding within the ICD-10-CM R35 group supports proper claim adjudication.

    ICD-10-CM R35: Polyuria Overview

    The ICD-10-CM R35 code group captures diagnoses related to excessive urine production and frequency known as polyuria. These conditions target the genitourinary system and often reflect underlying endocrine, renal, or fluid-balance disorders. Accurate coding matters for complete clinical documentation and appropriate reimbursement because it links symptoms to underlying causes and supports claim adjudication.

    When to Use

    Use a code from this group when the clinical record documents excessive urine output or a diagnosis of polyuria as the primary symptom or concern. Select more specific codes when a documented underlying cause or associated condition is identified in the medical record.

    Typical Clinical Scenarios

    • A 55-year-old woman with longstanding type 2 diabetes presents to the clinic complaining of a several-week history of excessive urination with increased urine volume both day and night, accompanied by polydipsia but no fever or dysuria. Point-of-care glucose and basic metabolic panel are ordered to evaluate glycemic control and possible osmotic diuresis; since the primary symptom is increased urine volume without evidence of infection or other specific anatomic urinary pathology, a polyuria symptom code is assigned. Typical codes: R35.0, R35.1
    • A 28-year-old otherwise healthy male is seen urgently after a multi-day episode of sudden onset large-volume urination and nocturia following initiation of a new diuretic medication while hiking; he denies dysuria or hematuria and vitals are stable. The presenting complaint is an acute increase in urine production temporally related to medication use, prompting evaluation for drug-induced diuresis and volume status; a polyuria code reflecting the symptom is used in the problem list. Typical codes: R35.0, R35.81
    • An 80-year-old nursing home resident with benign prostatic hyperplasia and chronic urinary frequency develops progressive large-volume voids and caregiver concern for incontinence versus overflow; after evaluation the predominant issue is increased urine output rather than retention or infection. Because the clinical issue is excessive urine volume as a comorbidity complicating management and caregiving, a polyuria symptom code is documented to capture the symptom contributing to functional decline. Typical codes: R35.0, R35.89
