2025 ICD-10-CM code R35
Polyuria.
Medical necessity for the workup of polyuria is established by the presence of the symptom itself, as it can be an indicator of underlying medical conditions requiring diagnosis and treatment.The medical necessity for further tests and procedures will be determined by the suspected underlying cause and clinical judgment.
Clinicians should investigate the underlying cause of polyuria, considering conditions like diabetes, kidney disease, or medication side effects. Accurate documentation of frequency, volume, and timing of urination, along with associated symptoms, is essential.
In simple words: Excessive urination.
Polyuria. Includes: Frequency of micturition, Nocturia. Excludes1: psychogenic polyuria (F45.8). Code first, if applicable, any causal condition, such as: enlarged prostate (N40.1)
Example 1: A patient with newly diagnosed type 2 diabetes presents with polyuria, polydipsia, and polyphagia. R35 is coded along with E11.9 for type 2 diabetes mellitus without complications., A patient with benign prostatic hyperplasia (BPH) experiences polyuria and nocturia due to incomplete bladder emptying. R35 and N40.1 are coded to reflect both the symptom and the underlying cause., A patient reports increased urination after starting a new diuretic medication. R35 is coded, and the medication is documented as the likely cause.
Documentation should include frequency and volume of urination, duration of symptoms, any associated symptoms (e.g., thirst, weight loss), relevant medical history (e.g., diabetes, kidney disease), current medications, and results of any diagnostic tests performed (e.g., urinalysis, blood glucose).
** Polyuria is a symptom, not a disease in itself. Therefore, it's crucial to identify and treat the underlying cause.
