Other lower urinary tract calculus
ICD-10 N21.8 is a billable code used to indicate a diagnosis of other lower urinary tract calculus.
N21.8 refers to the presence of calculi (stones) located in the lower urinary tract, which includes the bladder and urethra. These calculi can result from various factors, including metabolic disorders, dietary habits, and dehydration. Symptoms often include hematuria (blood in urine), dysuria (painful urination), and urinary obstruction, which can lead to significant discomfort and complications if not treated. The management of lower urinary tract calculi may involve conservative measures such as increased fluid intake and dietary modifications, as well as more invasive procedures like lithotripsy or surgical stone removal. Lithotripsy utilizes shock waves to break stones into smaller pieces, facilitating their passage through the urinary tract. Surgical interventions may be necessary for larger stones or those causing severe obstruction. Understanding the underlying causes and appropriate treatment options is crucial for effective management and prevention of recurrence.
Detailed patient history, imaging results, and treatment plans must be documented.
Patients presenting with hematuria, flank pain, or urinary obstruction due to calculi.
Urologists must document the size, location, and composition of stones for accurate coding.
Dietary assessments and recommendations for stone prevention must be included.
Patients with recurrent stones requiring dietary modifications.
Nutritionists should document specific dietary changes and patient adherence.
Used for patients with calculi requiring non-invasive treatment.
Document the size and location of the stone, as well as the number of sessions.
Urologists must ensure proper coding based on the type of lithotripsy performed.
Common causes include dehydration, dietary factors (high oxalate or calcium intake), metabolic disorders, and urinary tract infections.
Diagnosis typically involves imaging studies such as ultrasound or CT scans, along with urinalysis to assess for stone composition.
Treatment options include increased fluid intake, dietary modifications, lithotripsy, and surgical removal of stones.
