Understanding Increased Urinary Frequency

Increased urinary frequency, also known as pollakiuria, is a common symptom characterized by the need to urinate more often than usual. While the definition of “normal” urinary frequency varies from person to person, most adults urinate between 6 and 8 times per day. Increased urinary frequency is generally defined as urinating more than 8 times in a 24-hour period, excluding nighttime urination (nocturia). It’s important to distinguish increased urinary frequency from other urinary symptoms such as urgency (a sudden, compelling need to urinate) and incontinence (involuntary leakage of urine).

The causes of increased urinary frequency are diverse and can range from simple lifestyle factors to serious medical conditions. It is crucial to consider the patient’s medical history, physical examination findings, and other associated symptoms to determine the underlying cause. Some common causes include:

* **Urinary Tract Infections (UTIs):** UTIs are a frequent cause of increased urinary frequency, particularly in women. The infection irritates the bladder lining, leading to a more frequent urge to urinate.
* **Overactive Bladder (OAB):** OAB is a condition characterized by a sudden, uncontrollable urge to urinate, often accompanied by increased urinary frequency and nocturia.
* **Diabetes:** Both type 1 and type 2 diabetes can cause increased urinary frequency due to the kidneys attempting to eliminate excess glucose from the blood.
* **Pregnancy:** The growing uterus puts pressure on the bladder, leading to increased urinary frequency.
* **Prostate Enlargement (BPH):** In men, an enlarged prostate can compress the urethra, causing urinary frequency, urgency, and difficulty emptying the bladder.
* **Interstitial Cystitis (IC):** Also known as painful bladder syndrome, IC is a chronic condition that causes bladder pain, urgency, and frequency.
* **Medications:** Certain medications, such as diuretics (water pills), can increase urine production and lead to increased urinary frequency.
* **Fluid Intake:** Excessive fluid intake, especially caffeinated or alcoholic beverages, can increase urine production and frequency.
* **Anxiety:** Anxiety and stress can sometimes trigger increased urinary frequency.

ICD-10 Coding for Increased Urinary Frequency

The International Classification of Diseases, Tenth Revision (ICD-10) is a standardized diagnostic tool used for classifying and coding diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. When coding for increased urinary frequency, it’s crucial to select the most accurate and specific code that reflects the underlying cause of the symptom. Here’s a breakdown of the relevant ICD-10 codes:

* **R35 – Polyuria:** While *polyuria* technically refers to the production of abnormally large volumes of urine, it is sometimes used interchangeably with increased urinary frequency in coding. However, it is important to understand the distinction between the two. Polyuria is a quantitative measurement (volume), while increased urinary frequency is a qualitative assessment (number of times).
* **R39.1 – Other difficulties with micturition:** This code is a more general code that can be used for various urinary symptoms, including increased urinary frequency, urgency, hesitancy, and straining. This code is often used when a more specific diagnosis cannot be established.
* **N39.41 – Urge incontinence:** While not directly coding for frequency, this code is relevant if the increased frequency is related to urge incontinence.
* **Specific Codes for Underlying Conditions:** The most accurate coding practice involves identifying and coding the underlying condition causing the increased urinary frequency. For example:
* N30.0 – Acute cystitis
* N40 – Benign prostatic hyperplasia
* E11.65 – Type 2 diabetes mellitus with hyperglycemia
* O26.4 – Urinary tract infection in pregnancy

**Key Considerations for Accurate Coding:**

* **Specificity:** Always strive to use the most specific code available. Avoid using unspecified codes when a more precise diagnosis can be made.
* **Underlying Cause:** Identify and code the underlying cause of the increased urinary frequency whenever possible. This provides a more complete and accurate clinical picture.
* **Documentation:** Ensure that the patient’s medical record clearly documents the increased urinary frequency, associated symptoms, and any relevant diagnostic findings.
* **Coding Guidelines:** Adhere to the official ICD-10 coding guidelines provided by the Centers for Medicare & Medicaid Services (CMS) and other relevant organizations.

Diagnostic Evaluation of Increased Urinary Frequency

A thorough diagnostic evaluation is essential to determine the underlying cause of increased urinary frequency. The evaluation typically includes:

* **Medical History:** A detailed medical history, including information about the onset, duration, and severity of the symptom, as well as any associated symptoms, medical conditions, medications, and lifestyle factors.
* **Physical Examination:** A physical examination, including abdominal and pelvic examination, to assess for any abnormalities.
* **Urinalysis:** A urinalysis to detect signs of infection, blood, or other abnormalities in the urine.
* **Urine Culture:** A urine culture to identify any bacteria in the urine and determine the appropriate antibiotic treatment.
* **Postvoid Residual (PVR) Measurement:** A PVR measurement to assess how well the bladder is emptying. This can be done using ultrasound or catheterization.
* **Urodynamic Testing:** Urodynamic testing may be recommended in some cases to assess bladder function and identify any abnormalities.
* **Cystoscopy:** A cystoscopy, which involves inserting a thin, flexible tube with a camera into the bladder, may be performed to visualize the bladder lining and identify any abnormalities.

Treatment Options for Increased Urinary Frequency

The treatment for increased urinary frequency depends on the underlying cause. Some common treatment options include:

* **Antibiotics:** Antibiotics are used to treat urinary tract infections.
* **Medications for Overactive Bladder:** Medications such as anticholinergics and beta-3 agonists can help to reduce bladder spasms and urgency.
* **Lifestyle Modifications:** Lifestyle modifications, such as reducing caffeine and alcohol intake, avoiding bladder irritants, and practicing bladder training techniques, can help to improve urinary frequency.
* **Pelvic Floor Exercises:** Pelvic floor exercises (Kegel exercises) can help to strengthen the pelvic floor muscles and improve bladder control.
* **Surgery:** Surgery may be an option for some underlying conditions, such as prostate enlargement.

The Role of Mirabegron in Managing Urinary Frequency

Mirabegron, marketed under the brand name Myrbetriq, is a beta-3 adrenergic agonist medication primarily used to treat overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency, and urinary frequency. It works by relaxing the detrusor muscle of the bladder, which increases bladder capacity and reduces the urge to urinate frequently.

From our experience working with urologists, Mirabegron offers a different mechanism of action compared to traditional anticholinergic medications, which are also used to treat OAB. Anticholinergics work by blocking the action of acetylcholine, a neurotransmitter that stimulates bladder muscle contraction.
