Built on public federal payer-rate data — no PHI, ever. See how it works
The timeline

You click Run Snapshot.
Here's every second of what happens next.

You're a busy clinician about to hand a software company your NPI. You're allowed to be skeptical. This is the full timeline — every API call, every render, every promise we make about what we do (and don't do) with the result.

Current production flow · reviewed June 2026
Step by step

From click to underpayment matrix,
in about 15 seconds.

  1. T+0s

    You click Run My Free Snapshot.

    Your NPI is submitted to our API over TLS 1.3. No file is uploaded. No CSV. No claim data. Just ten digits.

    // POST /api/snapshot · 1 field
  2. T+0–3s

    We resolve your NPI against the federal NPI Registry.

    One call to the public CMS NPPES endpoint. We pull your practice name, primary taxonomy code (specialty), and primary practice ZIP. If the NPI doesn't resolve, we stop and tell you — no mock data, no fallback.

    // GET npiregistry.cms.hhs.gov · public · cacheable
  3. T+3–10s

    We look up your contracted rates.

    One query against Reddenda's own normalized rate index, built from 314M+ public federal Transparency-in-Coverage records across 500+ payers and all 50 states, scoped to your NPI and TIN. Where we have your rates, we return them. Where we don't, we say so honestly.

    // one indexed query · scoped to your NPI + TIN
  4. T+10–15s

    We compute the CMS PFS benchmark and peer percentile band.

    For every CPT we found, we compute the locality-adjusted Medicare allowed amount (using the GPCI for your ZIP) and the 25th / 50th / 75th percentile commercial rates among same-specialty peers in your state. Rates >5% below the peer 50th get flagged as underpayments.

    // percentile_cont(0.5) WITHIN GROUP · GPCI locality applied
  5. ~T+15s

    Your Snapshot renders. In your browser. Nobody emails you.

    The free Snapshot, top 3 CPTs against top 3 payers with dollar variance and one priority action, renders client-side. Results appear in your browser in about 15 seconds. No PDF is queued automatically. No email drip starts. No salesperson is paged. You see the result, save the link, and you're done unless you choose to upgrade.

    // rendered in about 15s · no server-side PDF · no email trigger
  6. Optional

    You choose whether to save or email yourself a copy.

    Optional, user-initiated. If you click "Email me a copy" or "Save to my account" the Snapshot is sent or stored. If you don't click anything, nothing leaves the page. There is no required email gate. No drip sequence. No sales call. No credit card.

    // user-initiated · no auto-send · no auto-store
After your snapshot renders

Three things we don't do, even if you'd let us.

A lot of "free tools" in healthcare are loss-leaders for an aggressive sales motion. We aren't one of them. Here's what we won't do, no matter how tempting the conversion math gets.

We don't email you.

No "your report is ready" drip. No "did you see your underpayment?" follow-up. No nurture sequence. You'll hear from us if you write us, or never.

We don't spam you.

No "schedule a call" pop-up. No retargeting pixel firing across the web. No outbound SDR with a slightly different subject line every Tuesday.

We don't sell your data.

Not to payers. Not to billing companies. Not to "industry researchers." Your NPI is public; your Snapshot interest is not, and it stays that way.

Data handling by tier

What we store depends on what you use.

The Free Snapshot and all public-data workflows operate on business-level inputs only. Claim-level and private workflows operate under separate terms.

Free Snapshot · Mode 1

Public-data workflow

Basic business-level inputs are processed to generate your Snapshot result: NPI, specialty, payer mix, CPT codes, volume estimates, ZIP code, and optional average reimbursement amounts.

Results appear in your browser in about 15 seconds. No PHI is required for the Free Snapshot. Users should not upload PHI into the public Snapshot workflow.

If you request an emailed copy, save the report, or create an account, the relevant business-level inputs and results may be stored. If you take none of those actions, nothing is retained beyond the session.

Paid Tiers · Mode 1 default

Paid audit and monitoring workflows

Data handling for paid tiers follows the same public-data-first approach as the Free Snapshot. Practice Audit, Leverage Memo, and Reddenda Pro tiers operate on the same public NPI, TiC, and CMS PFS inputs. No PHI required.

Claim-level, EOB, contract-PDF, or remittance-data workflows require private onboarding with separate compliance terms. A BAA may be required depending on the data involved. These are Mode 2 capabilities and are not available through the standard purchase flow.

To discuss Mode 2 onboarding, contact info@reimburseos.com.

Optional upgrade

If you decide you want the full picture.

// practice audit · one-time

One payment. Every CPT. Every payer.

one-time founding rate · list

If the free Snapshot's three CPTs surface a gap worth investigating, the Practice Audit unlocks the full picture. Same pipeline, same methodology, deeper output.

  • Top 20 CPTs analyzed against every payer in your state, not just the top 3
  • Full payer-specific underpayment matrix · dollar gap per code per payer
  • Leverage Memo, pre-written, with the rate-anchor table baked in
  • Contract renewal calendar with a 90-day prep window per payer
  • Founder's Promise: if the audit does not identify at least your specialty's Promise floor (set by specialty and practice size) in documented reimbursement opportunity across your submitted CPT and payer panel, we refund your fee. See your specialty's floor

Reddenda identifies documented opportunity based on public contracted rates and submitted practice inputs. Actual recovery depends on payer response, contract terms, documentation, and negotiation outcome.
