Definition
Medical toxicologists are physicians that specialize in the prevention, evaluation, treatment and monitoring of injury and illness from exposures to drugs and chemicals, as well as biological and radiological agents. Medical toxicologists care for people in clinical, academic, governmental and public health settings, and provide poison control center leadership. Important areas of medical toxicology include acute drug poisoning, adverse drug events, drug abuse, addiction and withdrawal, chemicals and hazardous materials, terrorism preparedness, venomous bites and stings, and environmental and workplace exposures.

Where 2080T0002X sits
- Group: Allopathic & Osteopathic Physicians — code 148 of 238 in the group
- Classification: Pediatrics 208000000X
- Specialization: Medical Toxicology 2080T0002X
Choose 2080T0002X over the general Pediatrics code (208000000X) when the provider's training or certification is specifically in medical toxicology; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
