Frequency of micturition

This code describes the symptom of abnormally frequent urination, often characterized by a need to void more often than usual during waking hours. It indicates a subjective complaint of increased urinary frequency without specifying an underlying cause.

Use this code when documentation indicates a patient's primary complaint is frequent urination, and a more specific diagnosis has not yet been established or is not applicable. It is appropriate for initial evaluations or when frequency is the sole symptom being addressed. Supporting documentation includes patient history, chief complaint, and review of systems.

• Do not use this code if a definitive diagnosis for the frequent urination (e.g., UTI, BPH, overactive bladder) is documented; instead, code the underlying condition.
• Consider sequencing this code as a secondary diagnosis if it is a significant symptom contributing to the patient's presentation but not the primary reason for the encounter.
• Distinguish from polyuria (R35.1), which refers to abnormally large volumes of urine, not just frequency.
