Records at 502 Madison Oak Dr

How this address was grouped
The normalized key is 502 MADISON OAK DR, San Antonio, TX 78258. The build uppercases the street, drops suite, unit, apartment, building, and floor tokens, and keeps the five-digit ZIP. 4 NPI-1 cardiology rows share that key in the 2026-11-09 extract. 4 have an adult profile URL. 0 are pediatric-only and have no /doctors/ page in this wave.
Sharing a street does not mean the people are partners, employees, or one medical group. NPI-2 organization names are printed only as registry strings. If none is stored, the page does not invent a brand. Telephone numbers stay on each row because suites at one street can list different numbers.
This page is not a hospital privilege list and not a quality report. It does not say who is accepting new patients. That field is not in the NPPES extract used here. The check date for the license flag in the table is 2026-11-09.
This address is not given a single clinic brand. NPI-2 organization names stored here: none.
No profile at this address is claimed. There is no appointment form. Each adult row links to a profile with that row's own telephone.
