ICD-10: R35.89

Polyuria, characterized by the production of abnormally large volumes of urine, can be indicative of various underlying health conditions. The ICD-10 code R35.89 specifically refers to "Other polyuria," which encompasses cases that do not fall under more specific categories of polyuria. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for accurate diagnosis and management.

Clinical Presentation

Definition and Overview

Polyuria is defined as the excretion of more than 3 liters of urine per day in adults. It can result from various physiological and pathological processes, including diabetes mellitus, diabetes insipidus, and certain medications. The "Other polyuria" classification (R35.89) is used when the polyuria does not fit into these more common categories, suggesting a need for further investigation into the underlying cause.

Common Causes

• Diabetes Mellitus: Uncontrolled diabetes can lead to osmotic diuresis, resulting in increased urine output.
• Diabetes Insipidus: This condition, characterized by a deficiency of antidiuretic hormone (ADH), leads to excessive urination.
• Medications: Certain diuretics and other drugs can induce polyuria.
• Psychogenic Polydipsia: Excessive fluid intake due to psychological factors can also cause increased urine output.

Signs and Symptoms

Key Symptoms

Patients with polyuria may present with the following symptoms:
- Increased Urination: Notable increase in the frequency and volume of urination.
- Thirst: Often accompanied by polydipsia (increased thirst), particularly in cases related to diabetes.
- Dehydration: Symptoms may include dry mouth, fatigue, and dizziness due to fluid loss.
- Electrolyte Imbalance: Potential signs include muscle cramps, weakness, and irregular heart rhythms, particularly if polyuria leads to significant fluid and electrolyte loss.

Physical Examination Findings

During a physical examination, healthcare providers may observe:
- Signs of Dehydration: Such as dry mucous membranes and decreased skin turgor.
- Vital Signs: Hypotension or tachycardia may be present if dehydration is significant.
- Neurological Assessment: Altered mental status may occur in severe cases due to electrolyte imbalances.
