L2: Completeness and plausibility
No placeholder values in price or payer fields
Warning · HPT-L2-014Values like 999999999, 'N/A', or an empty payer name are common placeholders hospitals leave in when a real number wasn't ready. They pass schema validation but carry no real pricing information.
545893 rows contain a placeholder value instead of real data.
Citation: CMS Hospital Price Transparency FAQ, data completeness guidance
Remediation: Replace placeholder values with the real negotiated rate, or omit the row if the rate genuinely doesn't exist for that payer/plan.
Affects 545,893 row(s).
L3: Discoverability compliance
cms-hpt.txt is present at the domain root and points at a live MRF
Blocker · HPT-L3-001Every hospital must publish a cms-hpt.txt file at the root of its public domain listing the location(s) of its machine-readable file(s). Without it, the MRF is effectively undiscoverable to anyone who doesn't already have the direct URL.
cms-hpt.txt not reachable at https://mymarinhealth.org/cms-hpt.txt (status 403).
Citation: CMS Hospital Price Transparency txt-file FAQ; 45 CFR 180.50(e)
Remediation: Publish a cms-hpt.txt file at https://<your-domain>/cms-hpt.txt listing the full URL(s) of your MRF(s), one per line.
MRF is publicly reachable without authentication or a JS wall
Blocker · HPT-L3-003The file must be fetchable by an anonymous, unauthenticated HTTP request. A login-gated page, a JavaScript-rendered viewer with no direct file link, or a 403/404 response means automated tools (including this one, CMS, and any payer trying to reconcile rates) can't actually read the file.
https://apim.services.craneware.com/api-pricing-transparency/api/public/cc145ba21e574ef7da4a1ed8325d54f9/charges/mrf returned status 404.
Citation: 45 CFR 180.50(b) — MRF must be accessible to the public without barriers
Remediation: Serve the MRF from a plain, unauthenticated URL that returns the raw CSV or JSON file directly, with no login or JavaScript required.
MRF filename follows the CMS naming convention
Warning · HPT-L3-002CMS expects the MRF filename to follow <ein>_<hospital-name>_standardcharges.<ext>. A non-conforming filename makes the file harder for automated tools (including CMS's own review process) to identify.
Filename "mrf" doesn't match <ein>_<hospital-name>_standardcharges.<ext>.
Citation: 45 CFR 180.50(b)(1)(i) — file naming convention
Remediation: Rename the file to <ein>_<hospital-name>_standardcharges.csv (or .json), using the hospital's EIN with no dashes.
