JOHN CARLSON, MD, PHD appears in the CMS NPPES registry as a Pediatrics Physician provider holding MD, PHD credentials at 1430 TULANE AVE # SL-37, NEW ORLEANS, LA, 70112, with a listed phone of (504) 988-5456. NPI 1700058310 was issued on 03/24/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CARLSON most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 49 prescription claims written by this provider, covering 15 Medicare beneficiaries and totaling roughly $231K in drug spend, split 76% brand-name and 24% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Pediatrics Physician is a high-volume specialty nationwide, with 80,574 enrolled providers across 56 states and an average of 762 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
