A18.13

Tuberculosis of other urinary organs

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/05/2025

Code Description

ICD-10 A18.13 is a billable code used to indicate a diagnosis of tuberculosis of other urinary organs.

Key Diagnostic Point:

Tuberculosis of other urinary organs refers to the infection caused by Mycobacterium tuberculosis affecting parts of the urinary system that are not the kidneys or bladder. This condition can manifest in various forms, including renal tuberculosis, which primarily affects the kidneys, but can also involve the ureters, urethra, and other urinary structures. Symptoms may include hematuria (blood in urine), dysuria (painful urination), and flank pain. Diagnosis typically involves a combination of clinical evaluation, imaging studies such as ultrasound or CT scans, and microbiological tests including urine cultures and PCR testing for Mycobacterium tuberculosis. Treatment usually consists of a multi-drug regimen over an extended period, often involving isoniazid, rifampicin, pyrazinamide, and ethambutol. Monitoring for drug resistance is crucial, as resistance can complicate treatment and prolong recovery. Public health implications are significant, as tuberculosis is a communicable disease, necessitating contact tracing and isolation procedures for active cases to prevent transmission. Regular follow-up and adherence to treatment protocols are essential to ensure successful outcomes and minimize the risk of drug-resistant strains.

  • Complex treatment regimens and monitoring for drug resistance

Audit Risk Factors

  • Inadequate documentation of diagnostic tests performed
  • Failure to document treatment adherence and monitoring
  • Misclassification of the site of infection
  • Lack of public health reporting for tuberculosis cases

Coding Guidelines

Inclusion Criteria

Use A18.13 When
  • According to ICD
  • 10 guidelines, A18
  • 13 should be used when tuberculosis is confirmed in urinary organs other than the kidneys or bladder
  • It is important to document the specific organ affected and any associated complications

Exclusion Criteria

Do NOT use A18.13 When
  • Exclusion criteria include cases where tuberculosis is primarily affecting the kidneys or bladder, which should be coded separately

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of tuberculosis cases, including those affecting the urinary system. This specificity aids in better tracking of disease prevalence and treatment outcomes, ultimately improving public health responses.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of tuberculosis cases, including those affecting the urinary system. This specificity aids in better tracking of disease prevalence and treatment outcomes, ultimately improving public health responses.
