2025 ICD-10-CM code A18.1
(Active) Effective Date: N/A Certain infectious and parasitic diseases - Tuberculosis 1 Feed
Tuberculosis of the genitourinary system.
Medical necessity for services related to A18.1 is established by the confirmed diagnosis of genitourinary tuberculosis through positive culture or other definitive diagnostic methods.Treatment is medically necessary to prevent serious complications like kidney damage, infertility, and further spread of the disease.
Clinicians diagnosing and managing genitourinary tuberculosis should evaluate symptoms (e.g., frequent urination, pain, blood in urine), conduct physical exams, and order tests like urinalysis, urine culture, imaging (ultrasound, CT, MRI), and biopsies to confirm the presence of Mycobacterium tuberculosis. Treatment involves a multi-drug regimen, typically lasting 6-9 months. Surgical intervention may be necessary for complications like abscesses, strictures, or extensive organ damage. Patient education is crucial, emphasizing adherence to medication and potential long-term effects.
In simple words: Genitourinary tuberculosis (GUTB) is a type of TB that affects the urinary and reproductive systems. It happens when TB bacteria spread from the lungs to these areas. GUTB can cause problems like frequent urination, pain, and blood in the urine. If left untreated, it can lead to serious complications like kidney damage and infertility.
Tuberculosis (TB) of the genitourinary system is a form of extrapulmonary tuberculosis affecting the kidneys, bladder, ureters, and reproductive organs. It occurs when Mycobacterium tuberculosis spreads from the lungs (usually a latent infection) through the bloodstream or lymphatic system to the genitourinary tract. The infection can lie dormant for extended periods before reactivating, causing inflammation, granulomas, fibrosis, and potential organ damage.
Example 1: A 35-year-old male presents with persistent dysuria, increased urinary frequency, and intermittent hematuria. Imaging reveals granulomas in the bladder and kidneys. Urine culture confirms the presence of Mycobacterium tuberculosis, leading to a diagnosis of genitourinary TB., A 50-year-old female with a history of latent TB experiences flank pain, fever, and weight loss.A CT scan shows renal lesions. Biopsy confirms renal TB, a component of genitourinary TB., A 28-year-old male experiences scrotal swelling and pain. Examination reveals epididymal involvement.Further investigation confirms Mycobacterium tuberculosis, indicating genital TB, a form of genitourinary TB.
Documentation should include details of the patient's symptoms, medical history (especially any prior TB diagnosis), physical exam findings, laboratory results (including urinalysis, urine culture, and any biopsies performed), imaging findings, and the prescribed treatment plan.
** Genitourinary TB can have long-term consequences even after successful treatment, including infertility and renal impairment. Regular monitoring is often recommended.
