Both campuses attest with James Mack's name. The CMS contact of record is someone else, and this is the third enforcement case since 2021.
Measured from The Methodist Hospitals, Inc.'s own published price transparency files for both campuses under 45 CFR Part 180.50 and 180.60, and CMS's own enforcement record, retrieved Sep 18, 2026.
| Facility | Legal entity | Location | CCN | Type | Beds | Ownership | Medicare since |
|---|---|---|---|---|---|---|---|
| Methodist Hospitals — Northlake Campus | The Methodist Hospitals, Inc. | Gary, IN | 150002 | Acute | 536 | Nonprofit | |
| Methodist Hospitals — Southlake Campus | The Methodist Hospitals, Inc. | Merrillville, IN | 150002 | Acute | 536 | Nonprofit |
Both campuses file under one CCN and one bed count, consistent with operating as a single licensed system across two physical sites rather than two separately certified hospitals.

SHARE OF EACH FILE CARRYING A PAYER-SPECIFIC RATE
1.6% of rows at either campus carry this year's required percentile figures
Of 22,449 rows at each campus, 362 carry the median/10th/90th percentile figures required since April. The two campuses are identical on this measure down to the row.
The listed CMS contact isn't the person who attests either file
cms-hpt.txt names Matthew Doyle as the contact for both campuses. The attestation field inside both files, the field CMS requires the CEO or the senior official overseeing data encoding to sign, names James Mack. Worth knowing which of the two is the right person for CMS's next correspondence to actually reach.
Two different files, structurally identical numbers
Northlake and Southlake publish separate files (different file hashes, different campus addresses in the metadata), but both carry exactly 22,449 rows, exactly 38 payer/plan combinations, and exactly the same dollar and percentile fill rates. Worth a direct question: does each campus negotiate its own rates, or does one contract set genuinely apply to both?
99.6% of rows at both campuses carry a real negotiated dollar amount
22,365 of 22,449 rows at each campus carry an actual dollar figure across 38 tracked payer/plan combinations — genuinely thorough filing on the harder half of the requirement, and identical between the two campuses down to the row count.
Are Northlake's and Southlake's rates genuinely negotiated as one contract set, or does the identical row count and fill rate reflect a shared template that hasn't been differentiated by campus?
If each campus negotiates separately, identical numbers down to the row would be an unusual coincidence worth checking.
Should CMS's contact of record be updated to James Mack, given he's the one named in both attestations?
This is now the third enforcement cycle since 2021. Making sure the right person receives CMS's correspondence directly could shorten however this one plays out.
