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

Public data only.
Zero PHI required.

You give us four fields. We compose the rest from public federal datasets that have always been there — rates that have always been public — locked inside files that require a data engineering team and terabytes of storage to open. Reddenda built the infrastructure so you don't have to.

TiC index · 2026-Q1 refresh · refreshed monthly

We never ask for, see, or store PHI.

Not patient names. Not DOBs. Not claim numbers. Not diagnoses. Not encounter notes. Our entire dataset is composed of public business identifiers (NPI) and public commercial rates (federal MRF filings). HIPAA-aligned by architecture, not by policy.

// our dataset

Reddenda owns and operates a normalized reimbursement dataset built on public federal filings.

We ingest, parse, and normalize federal Transparency-in-Coverage machine-readable files directly from each payer's CMS-mandated CDN. No private aggregator stands between the raw federal source and our index. TwinFlame Group owns and operates Reddenda. See the full methodology for the formulas and refresh cadence.

What we ask you for. What we pull ourselves.

// from you · 4 fields

What you provide

  • NPI10-digit identifier
    Your National Provider Identifier. Already public in the federal NPI Registry. Required.
  • Emailwork address
    Optional. If provided, we can email you a copy of your Snapshot. Results appear in your browser either way. We never sell it. We never share it. We don't drip-market you.
  • Practice nameauto-filled from NPI
    Auto-populated from the NPI Registry response. Editable if your DBA differs from your legal entity.
  • Specialtyauto-detected · taxonomy code
    Auto-detected from the primary taxonomy code on your NPI record. Editable if you bill under a secondary taxonomy.

What we compose for you

    Practice address, taxonomy, credentialing date, sole-proprietor flag. Refreshed weekly.
  • Contracted ratesTiC MRFs · 500+ payers
    Your in-network negotiated rate from every commercial payer's published MRF. 9.7M+ normalized rows indexed.
  • CMS PFS 2026RVU file · conversion factor
    Medicare allowed amount per CPT, the locality-adjusted floor for commercial comparison.
  • GPCI vector112 CMS localities
    Geographic Practice Cost Index for your locality. Normalizes for cost-of-practice variation across metros.
  • Peer percentile bandspecialty · state
    25th / 50th / 75th percentile commercial rates among same-specialty peers in your state.
// not part of the public-data workflow

Mode 1 does not use these inputs. Mode 2 workflows require separate compliance terms.

  • Patient names, addresses, phone numbers, emails
  • Patient dates of birth, SSN, MRN, member ID
  • Claim numbers, encounter IDs, prior auth numbers
  • Diagnosis codes (ICD-10) tied to a patient
  • Procedure notes, chart entries, imaging files
  • Remittance advice (835), claims files (837)
  • Billing-system credentials, EHR exports
  • Anything else that could re-identify a patient
  • Private payer portal scrapes or proprietary aggregator panels
// data basis labels

Every number in a Reddenda output carries one of four data basis labels.

These labels tell you exactly how a figure was calculated so you know how much weight to put on it before walking into a payer negotiation.

// basis 01

Exact TiC Public Contracted Rate

  • SourceFederal MRF filing
    We found a publicly filed contracted rate in a payer's federal Transparency-in-Coverage MRF that matches your NPI, payer, CPT code, geography, and available payer-file identifiers. This is the strongest basis available in the public dataset.
// basis 02

User-Entered Practice Rate

  • SourceYour input
    You entered your own current reimbursement, average allowed amount, or expected rate. We use your number as the "your rate" baseline and compare it against the public benchmark. Your rate is never substituted or overridden by our data.
// basis 03

Benchmark Estimate

  • SourceCMS PFS + GPCI + market data
    We estimated the opportunity using CMS Physician Fee Schedule locality adjustments, GPCI factors, commercial-to-Medicare benchmark research, specialty assumptions, payer mix, and available public market data. Labeled clearly as directional, not a confirmed contract figure.
// basis 04

Unavailable / Low Confidence

  • SourceInsufficient data
    We do not have enough reliable source data to confidently calculate this result. We label it "Unavailable," "Thin sample," or "Low confidence" rather than substituting a guess or a specialty average as if it were practice-specific.
// opportunity qualifier

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.

// npi and tin matching

We look up public contracted-rate records associated with your NPI, organization, taxonomy, geography, and available payer-file identifiers. Where TIN-level matching is required and unavailable, Reddenda labels the result as lower confidence rather than presenting it as confirmed. Healthcare rate files use multiple provider-reference structures. We surface what we can match and label everything else explicitly.

// compliance posture

The Free Snapshot and all public-data workflows operate in Mode 1: no PHI required. Users should not upload PHI into the public Snapshot workflow. If your use case requires claim-level, EOB, or remittance-data workflows, those require private onboarding with separate compliance terms. See the HIPAA-aligned workflow page for the full two-mode breakdown. Snapshot results appear in your browser in about 15 seconds.

9.7M+ rate rows indexed

Normalized contracted-rate rows built directly from federal Transparency-in-Coverage filings. 500+ commercial payers. All 50 states. No private aggregator in the chain.

Four public inputs, one composed output

NPI Registry + TiC MRFs + CMS PFS + GPCI locality vector. Every benchmark links to its federal source file. Nothing invented. Every figure carries its data basis label.

Zero PHI — by architecture

We never route PHI through our system. No BAA required for the Free Snapshot. HIPAA-aligned by design, not by policy claim.
