208000000X Pediatrics Physician

Definition

A pediatrician is concerned with the physical, emotional and social health of children from birth to young adulthood. Care encompasses a broad spectrum of health services ranging from preventive healthcare to the diagnosis and treatment of acute and chronic diseases. A pediatrician deals with biological, social and environmental influences on the developing child, and with the impact of disease and dysfunction on development.

Where 208000000X sits

• Group: Allopathic & Osteopathic Physicians — code 142 of 238 in the group
• Classification: Pediatrics 208000000X

This is the general code for Pediatrics. 24 more specific codes sit beneath it; pick one of those when the provider's training or certification matches it, and this one otherwise. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

CMS's taxonomy crosswalk links 208000000X to Medicare specialty 37 (Physician/Pediatric Medicine). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 56,331 practitioners are enrolled under it nationally, and 23 other taxonomy codes map to the same specialty.

Other codes under the same Medicare specialty: 2080A0000X Pediatric Adolescent Medicine Physician; 2080B0002X Pediatric Obesity Medicine Physician; 2080C0008X Child Abuse Pediatrics Physician; 2080H0002X Pediatric Hospice and Palliative Medicine Physician; 2080I0007X Pediatric Clinical & Laboratory Immunology Physician; 2080N0001X Neonatal-Perinatal Medicine Physician; 2080P0006X Developmental - Behavioral Pediatrics Physician; 2080P0008X Pediatric Neurodevelopmental Disabilities Physician; and 15 more.

Similar codes in other groups

If 208000000X is not quite right, these codes in other groups share a word with it — often the same field practised by a different kind of provider:

• 152WP0200X Pediatric Optometrist (Eye and Vision Services Providers)
• 163WP0200X Pediatric Registered Nurse (Nursing Service Providers)
• 1835P0200X Pediatric Pharmacist (Pharmacy Service Providers)
• 364SX0204X Pediatric Oncology Clinical Nurse Specialist (Physician Assistants & Advanced Practice Nursing Providers)
• 364SP0200X Pediatric Clinical Nurse Specialist (Physician Assistants & Advanced Practice Nursing Providers)
• 363LP0200X Pediatric Nurse Practitioner (Physician Assistants & Advanced Practice Nursing Providers)

Using 208000000X

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.
