Tuberculosis of other female genital organs

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 A18.18 is a billable code used to indicate a diagnosis of tuberculosis of other female genital organs.

Key Diagnostic Point:

Tuberculosis of the female genital organs is a rare but serious manifestation of extrapulmonary tuberculosis, primarily caused by Mycobacterium tuberculosis. This condition can affect various structures within the female reproductive system, including the ovaries, fallopian tubes, uterus, and vagina. Symptoms may include pelvic pain, abnormal vaginal discharge, and infertility. Diagnosis typically involves a combination of clinical evaluation, imaging studies such as ultrasound or MRI, and microbiological tests, including culture and PCR for Mycobacterium tuberculosis. Treatment usually consists of a multi-drug regimen similar to that used for pulmonary tuberculosis, often requiring a prolonged course of therapy lasting six months or longer. Monitoring for drug resistance is crucial, as some strains may exhibit resistance to first-line anti-tubercular medications. Public health implications are significant, as tuberculosis is a communicable disease, necessitating contact tracing and isolation procedures for active cases to prevent transmission. The rarity of this condition, combined with its complex presentation and treatment requirements, makes accurate coding essential for proper management and reimbursement.

Audit Risk Factors

  • Inadequate documentation of diagnostic tests performed
  • Failure to document the specific female genital organ affected
  • Lack of clarity on treatment regimen and duration
  • Insufficient follow-up documentation to support ongoing treatment
