Source the rule. Separate the systems. Preserve the date.

1. Start with first-party material

For Medicare enrollment, the primary source is CMS: enrollment pages, current CMS-855 materials, PECOS guidance, Medicare Learning Network education, and CMS data tools. For CAQH-specific profile operations, the primary source is CAQH’s Provider Data Portal material. We avoid treating a consulting company’s checklist as the source of a federal or CAQH rule.

2. Keep payer-specific claims narrow

Commercial payer workflows differ. When a guide discusses a generic payer operation—credentialing, contracting, enrollment, effective dates, EFT/ERA, or directory setup—it describes the operational distinction without claiming that every payer uses the same form, deadline, or portal sequence.

3. Date the review

Each guide carries a reviewed date and links to the source material used. Form revisions matter: an old office SOP can remain internally consistent while becoming wrong after CMS changes a form or transaction path.

4. Test the content for mass-production footprints

Before release, the repository runs cross-guide six-gram Jaccard similarity, exact repeated sentence checks, repeated heading checks, word-depth checks, source-domain checks, orphan-route checks, and leak-phrase scans. Automated QA is not treated as proof of editorial quality; sample articles are also read manually for awkward repetition and “same article with nouns swapped” structure.

5. Update from the source of truth

When guidance changes, the goal is not to patch one sentence. We identify which guides rely on that rule, update the affected workflows, and rerun duplication/content QA so an update does not accidentally introduce boilerplate across the library.
