  • ICD-9-CM V09.91 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, V09.91 should only be used for claims with a date of service on or before September 30, 2015.

  • Infection resistant to multiple drugs
  • Infection with microorganisms resistant to drugs
  • Multidrug resistant tuberculosis
  • Multiple drug resistant pulmonary TB
  • Tuberculosis (TB) lung, resistant to multiple drugs
Clinical Information
  • Adaptation of tumor cells to anticancer drugs in ways that make the drugs less effective
  • Characteristic of certain cancer cells and infectious microorganisms, where resistance develops to a broad variety of chemically unrelated drugs; may be due to genetic induction of a membrane pump (p glycoprotein) or other mechanisms
  • Simultaneous resistance to a spectrum of unrelated drugs following exposure to a single agent. It may result from overexpression of the integral plasma membrane protein, p-glycoprotein. This adaptation of tumor cells to anticancer drugs, mediated by inactivation of the drug or removing it from the target tumor cells, tends to make the drugs less effective
Applies To
  • Multiple drug resistance NOS
