2025 ICD-10-CM code A18.11
(Active) Effective Date: N/A Certain infectious and parasitic diseases - Tuberculosis of kidney 1 Feed
Tuberculosis of kidney and ureter
Medical necessity for services related to A18.11 is established by the presence of signs, symptoms, and laboratory/imaging findings consistent with active tuberculosis of the kidney and ureter.The documentation should clearly demonstrate the need for diagnostic testing, treatment (medication and/or surgery), and follow-up care to address the active infection and prevent further complications.
Clinicians diagnosing A18.11 should consider symptoms like frequent urination, painful urination (dysuria), pus in the urine (pyuria), and back/flank/abdominal pain.General TB symptoms such as fever, night sweats, and weight loss may also be present. Diagnostic workup may include blood tests, tuberculin skin test, imaging (intravenous urography, MRI, or CT), and ultimately, confirmation through tissue biopsy or abscess sample analysis for acid-fast bacilli (AFB). Treatment typically involves antituberculous medications (e.g., isoniazid, rifampin, pyrazinamide, ethambutol) and potentially surgery for complications like abscesses, strictures, or fistulas.
In simple words: This code indicates tuberculosis that has spread to the kidneys and the tubes that carry urine from the kidneys to the bladder.
This code represents a diagnosis of tuberculosis affecting both the kidney and ureter.It's a specific type of extrapulmonary tuberculosis (EPTB), meaning it occurs outside the lungs. The infection typically originates elsewhere in the body, often the lungs, and spreads to the kidneys and ureters through the bloodstream or lymphatic system.It can remain dormant for extended periods before becoming active.
Example 1: A patient presents with persistent flank pain, dysuria, and fever.Imaging reveals granulomas on the kidney, and AFB is detected in a urine sample, confirming the diagnosis of tuberculosis of the kidney and ureter., A patient with a history of pulmonary tuberculosis develops symptoms of urinary tract infection.Further investigation, including urine cultures and imaging, shows evidence of tuberculosis affecting both the kidney and the ureter, now classified as active EPTB., During a routine check-up of a patient with latent TB, a urine test unexpectedly reveals the presence of Mycobacterium tuberculosis. Subsequent imaging confirms involvement of the kidney and ureter, prompting initiation of treatment for active EPTB, despite the absence of overt symptoms.
Documentation for A18.11 should include evidence of active Mycobacterium tuberculosis infection in both the kidney and ureter. This can be supported by positive AFB smears or cultures from urine or tissue samples, imaging studies showing characteristic lesions (granulomas, tuberculomas), and clinical findings consistent with genitourinary TB.Prior history of TB, relevant symptoms, and treatment details should also be documented.
