Short, sourced explainers on the model's reporting deadlines, validity windows, and provenance rules — each one traced back to CMS's own documents, so you can read the source yourself. This is the reference we wish existed when we started building the rail.
Short reads that walk the rules in the order they bite: first the two clocks that govern when you submit, then the windows and methods that govern whether a reading is eligible in the first place. Best read in order.
ACCESS has one deadline that unaligns a beneficiary and one rolling window that isn't what "quarterly" sounds like. Both come from CMS's own payment paper.
Read it →The ACCESS quarterly reporting window is anchored to your previous submission, not the calendar. Here's the arithmetic of how the window actually moves — from CMS's own payment paper.
Read it →Under the ACCESS model, a reading is only eligible if it was collected inside its freshness window. Here are the six windows — and the collection-method rule behind them — straight from CMS's own documents.
Read it →Under the ACCESS model, a reading can be disqualified before it's ever submitted — by *how* it was captured. Here are the collection-method rules, straight from the RFA.
Read it →The ACCESS end-of-period measure has a hard outer deadline at Day 425 — but the *early* window that most teams should actually target is measured backward from a different day. Here's the math, straight from the Payment paper.
Read it →In the ACCESS model, a submission can be accepted the day you send it and still fail eleven months later at reconciliation. That gap — between "accepted today" and "survives the year-end audit" — is a specific, buildable engineering problem. Here's how we think about it.
Read it →The first question a security reviewer asks a reporting vendor is "where does our PHI sit in your cloud?" For an ACCESS-model pilot with us, the honest answer is: it doesn't. Here's the architecture, the one narrow data channel, and — read this part — the list of what we don't have yet.
Read it →Half of the Medicare portion of every ACCESS payment is withheld until CMS reconciles your outcomes — and a beneficiary you never reported still counts against your attainment threshold. Here's how a single slipped window turns into dollars, walked through honestly, with the numbers CMS actually published (and the one it hasn't).
Read it →Device, lab, and PROM data in; compliant FHIR submissions out — validity windows, cadence clocks, and provenance rules enforced before CMS ever sees the bundle. We're onboarding a small founding cohort of design partners this quarter.
