How the atlas is built.
Rx Atlas covers pharmacists billing the medical benefit: getting paid as a provider for visits, tests, and vaccines, not for dispensing. When someone tells you pharmacists can bill in your state, this is where you check whether that’s true, and what it actually takes.
Primary sources only
Every entry traces to state code, board of pharmacy rules, Medicaid provider manuals, or payer policy documents. Secondary commentary informs the survey; it never serves as the citation.
Authority ≠ payment
A state authorizing a service is not the same as a payer reimbursing it. The atlas records both layers separately: scope-of-practice authority and payment mandate, with the gap between them made explicit.
Tiers describe today
Tier I means a claim can be paid now, with the prerequisites listed. Tier II means the law exists but payment still runs through a gate. Tier III means passed or pending: worth tracking, too early to build on.
Reviewed as laws move
Each state shows the date it was last reviewed. Legislation in flight is tracked but never presented as billable until rules, provider types, and payment systems are actually live.
Spotted something stale?
Fifty-one legislatures, fifty-one Medicaid programs, and payer policy that changes without a press release. If your state’s page no longer matches reality, say so. Corrections that point to a source get fixed fastest.
