Who pays, from which budget, how much, and 2-4 commercial routes to first revenue — every figure below traces to a copied claim or a declared assumption, and the routes are laid out unranked. Choosing a commercial strategy is a Tier 3 act, so this page presents options and stops.
Intended use: For use in the home under prescription to deliver phototherapy to newborns of at least 35 weeks gestational age with uncomplicated indirect hyperbilirubinemia whose total serum bilirubin is above the phototherapy threshold but below the escalation-of-care threshold, as an alternative to inpatient readmission for phototherapy.
There are two cheques in this chain, written by different people for different things: the party that buys the device is not the party that pays for the therapy, and the second one sets the ceiling on the first. What changed since the last build is that the code and its Medicare rate are now on the record. What did not change is that neither of them belongs to the payer this population actually has.
adoption returns unverifiable on that line and the domain dossier
records that no source located names the actual US purchaser of a home phototherapy unit. The
first link in the chain is still an assumption.
hcpcs S9098) bundles equipment rental with nursing services
and blood draw. If the payers that matter pay home phototherapy under S9098 rather than E0202
[assumption A1], the device is not paid for as a device at all: it is a cost inside a home
health provider's per-diem, and the buyer becomes that provider rather than a DME supplier.
Six questions, each with its own evidence position and one basis. No score, no tier, no composite. Read the coverage line first, then read the paragraph under it, because the one pillar that rests on a verified claim is the one that decides the least.
| # | Question | Finding | Basis |
|---|---|---|---|
| 2a | Coding route — Cat I / Cat III / unlisted / HCPCS (Healthcare Common Procedure Coding System) II / none | HCPCS Level II, not CPT (Current Procedural Terminology). E0202 exists, descriptor "Phototherapy (bilirubin) light with photometer", action code N, no termination date claim 3verified. The descriptor names a photometer, so a unit without one does not meet the descriptor text claim 4verified. Two limits the claim itself records: whether "with photometer" is a payment condition rather than descriptor wording is DME MAC (durable medical equipment Medicare administrative contractor) / payer-edit territory the HCPCS file cannot settle, and Level II is national code existence, silent on which code a Medicaid or commercial payer actually pays home phototherapy under. The competing code is S9098, a per-diem service code claim 4verified, and which of the two the payers that matter use is [assumption A1] | claim 3verified |
| 2b | Payment adequacy — does the rate clear a stated cost floor | No cost floor has ever been stated, so the question cannot yet be asked. Medicare's E0202 allowable is $75.86 (AZ) to $89.25 (AL) non-rural, on one RR capped-rental line billed per rental month, with no purchase line claim 5verified; that is Medicare's rate for a population with no Medicare exposure claim 6unconfirmed. The one Medicaid figure is Louisiana's $33.71 (modifier 09) and $30.90 (modifier 07) claim 44unconfirmed, on a billing unit nobody has established claim 51unconfirmed. Whether a monthly-rental payer pays a full month for a 2-4 day episode is [assumption A2]. The floor itself, the supplier's fully-loaded per-episode cost, is unsourced | claim 52unconfirmed |
| 2c | Practice-expense headroom — does the PE portion cover the device | No practice-expense portion on this route, by construction, on the record only as an assumption. E0202 is a DMEPOS code priced on the DMEPOS fee schedule claim 5verified; rvu E0202 --device-cost run this build returned no row in the cached PFS (physician fee schedule) RVU (relative value unit) file. That result is written back as a proposition for the Verifier rather than cited as a finding, because this case cannot issue a tag. A PE question would arise only if the device were furnished incident to an office service, which is not this business | [assumption A3] |
| 2d | Site of care & bundling — office/facility differential, DRG or APC packaging | Home, supplier-billed, and the bundling risk is a per-diem, not a DRG. For Medicare the structure is verified: monthly capped rental, title passing after 13 continuous rental months claim 5verified. For the payers that matter, the exposure is that home phototherapy is paid under S9098, whose per-diem bundles equipment with nursing and blood draw, so the device earns nothing separately [assumption A1]. No DRG or APC packages an item dispensed to a home; drg and apc returned missing-cache unconfirmed, a tooling gap. The DRG bites on the comparator instead: the avoided readmission [assumption A4] | [assumption A1] |
| 2e | Coverage — has any payer agreed to pay for this indication | No payer is on record agreeing to cover it. coverage E0202 returns no policy naming the code in the cached Medicare Billing & Coding Articles export, which the candidate records with its limits (articles only; names-the-code, not is-covered) inside claim 5verified, whose tag is about the fee and not about coverage. Louisiana paying E0202 claim 44unconfirmed is a payment line, not a coverage criterion. Whether the largest birth states publish a coverage policy is open | claim 23unconfirmed |
| 2f | Ex-US pathway — DE NUB/G-DRG, UK NICE (National Institute for Health and Care Excellence)/OPCS-4 | Permanently unconfirmed, and not under-researched. launch_jurisdiction: is US; no connector reaches a non-US payment system, and no claim in the candidate speaks to one in any direction | — none |
Pillars on verified claims: 1/6 · on assumptions: 2 · queued as research: 0
The other three: 2b rests on claim 52unconfirmed, 2e on claim 23unconfirmed, and 2f on nothing. Read the split before the six. The Verifier's most recent pass moved the code, its descriptor and its Medicare fee to verified, and that is real: the three-part test now reads code exists, Medicare allowable exists, no cached Medicare article names it. But the one pillar that rests on a verified claim is 2a, and 2a is code existence. Everything that turns a code into money for this population (a Medicaid or commercial rate on a known unit, a cost floor under it, a coverage policy, and whether the payer pays the equipment code at all) is unconfirmed or assumed. A verified Medicare fee for a newborn device is a verified fact about the wrong payer.
Three distinctions kept apart deliberately:
Verdicts recorded where a check was run and came back unusable, rather than routed around:
python3 -m connectors rvu E0202 --device-cost 100 --jurisdiction US → refuted —
`"No code E0202 in the cached CMS (Centers for Medicare & Medicaid Services) Physician Fee Schedule RVU file. It is not priced under the
PFS — it may still be paid under OPPS, the ASC list or DMEPOS, none of which this connector
reads."` The device-cost argument was a placeholder with no row to test it against; the
result is carried as [assumption A3] for the Verifier, not as a tag.
python3 -m connectors hcpcs S9098 --jurisdiction US → verified (code exists, per-diem,
descriptor bundles equipment rental, nursing services, blood draw and supplies);
payment S9098 → refuted, no row in the cached CMS payment files; coverage S9098 →
refuted, no cached policy names it; procedures S9098 → refuted, no Medicare row.
An S-code is a temporary national code for non-Medicare payers, so all three Medicare
absences are the expected result and say nothing about Medicaid or commercial use, which is
exactly what [assumption A1] asks.
python3 -m connectors drg 794, drg 795, apc E0202, icd P59.9 → **unconfirmed — no
local cache** (ms_drg_weights.csv, opps_addendum_b.csv, icd10cm.csv). Build-environment
gaps, not findings. MS-DRG is Medicare's grouper in any case; the newborn readmission is paid
under state Medicaid groupers no connector reaches.
python3 -m connectors cpt — not run. No CPT code or descriptor carries any part of this
case; the route is HCPCS Level II throughout, and no descriptor is reproduced here.
There is no market model for this candidate (the market-models shelf has no file for it), so this section does not size anything. A size is a chain with its own spec and its own checker, and building one here is the thing docs/commercial-spec.md §5 forbids. The legs the file carries are quoted, unmultiplied, so the next pass can pick them up. The rest of the model is unit economics: what one episode earns and what one fleet unit has to repay.
| Line | Figure | Backing |
|---|---|---|
| Size leg — US births, the denominator | 3,628,934 in 2024 | claim 36unconfirmed |
| Size leg — commensurability of an all-births denominator with a 35-plus-week rate | not established | claim 50unconfirmed |
| Size leg — share of 35-plus-week newborns who receive phototherapy | 8-12%, a Generator figure the dossier could not source | claim 8unconfirmed |
| Size leg — independent read on the post-discharge slice | 1.8% of 148,162 KPNC infants exceeded threshold after discharge | claim 37unconfirmed |
| Size leg — share of treated newborns home-eligible | 25-40%, the Generator's own assumption | claim 9unconfirmed |
| Which code the paying payers use for home phototherapy | E0202 (device paid) vs S9098 (device inside a per-diem) | [assumption A1] |
| Medicare allowable for E0202 — for scale only, not this population's payer | $75.86-$89.25 per rental month, RR line only, no purchase line | claim 5verified |
| Medicaid allowable for E0202, one state | $33.71 (modifier 09) and $30.90 (modifier 07), Louisiana | claim 44unconfirmed |
| Billing unit of that Medicaid allowable | per day, per month, per episode or purchase — unresolved | claim 51unconfirmed |
| Whether a monthly-rental payer pays a full month for a short episode | one full month vs prorated | [assumption A2] |
| Episode length | 2-4 days plus setup | claim 10unconfirmed |
| Whether Medicaid rather than commercial rates set the effective price | not established; the file's "roughly 40%+" Medicaid birth share is itself uncited | claim 63unconfirmed |
| Supplier's fully-loaded cost per episode (delivery, setup, training, retrieval, reprocessing) | not established | claim 52unconfirmed |
| Whether any supplier margin survives that cost | asserted, not measured | claim 24unconfirmed |
| Reprocessing between rental patients, or single-patient BOM (bill of materials) | unresolved on both routes | claim 29unconfirmed |
| Price a supplier pays per fleet unit | not established | claim 53unconfirmed |
| Episodes per fleet unit per year (turns) | not established | claim 54unconfirmed |
| Share of addressable episodes on this device by year 3 | not established | claim 55unconfirmed |
| Gross margin on the device at the fleet price | not established | claim 56unconfirmed |
| Incremental payment earned by the dose record | none found: one RR line, no dose-record modifier | claim 57unconfirmed |
Read the per-episode line before anything else. The revenue one episode earns is a product of three open questions: which code is paid [assumption A1], on what unit claim 51unconfirmed, [assumption A2], and at whose rate claim 63unconfirmed. Between a per-diem that absorbs the device and a full rental month billed for a 2-4 day episode claim 10unconfirmed, the spread is not a margin question but a question of whether a device line exists. The only published economic evidence points nowhere: a 2026 review of 31 studies found none evaluating cost-effectiveness of home phototherapy claim 40unconfirmed.
The two connectors a business case would ordinarily lean on both refuse, and the verdicts go on the page:
python3 -m connectors market "Annual US home phototherapy episodes for newborns of at least 35 weeks with uncomplicated hyperbilirubinemia, priced at the E0202 allowable, form an addressable market for a dosimetry-equipped wearable" → unverifiable — "has no free, authoritative, machine-queryable source. Stays unconfirmed permanently unless a human attaches a licensed report and edits the claim by hand." (market takes no --jurisdiction flag.)
python3 -m connectors adoption "A DME supplier stocking a home phototherapy rental fleet will choose a dosimetry-equipped wearable over the already-cleared SnugLit wearable (K251308)" → unverifiable — "asserts what clinicians, payers, or patients would do. No free, authoritative, machine-queryable source answers that — it needs primary research ... Do NOT substitute a model's own estimate of stakeholder behaviour: a synthetic stakeholder opinion is a fabricated claim." The same line is on the candidate at claim 34unconfirmed.
python3 -m connectors adoption "State Medicaid programs and commercial plans in the largest US birth states pay newborn home phototherapy under S9098 rather than E0202" → unverifiable, same detail. Its connector-suggested proxies are Medicare-shaped and blind here; the real falsifier is a read of four state fee schedules, which is why it is in the register.
procedures E0202 → refuted, no national row in the Medicare DMEPOS utilization release; as the candidate already records, that is a Medicare FFS (fee-for-service) absence for a population with no Medicare exposure, not a zero-volume floor claim 6unconfirmed.
Four, laid out side by side and not ordered. Choosing among them is a Tier 3 act; this section presents them and stops.
The file's own model: hardware sold to DME suppliers who rent to families and bill Medicaid or commercial plans under E0202 claim 22unconfirmed.
Vertically integrated: enrol as the provider, deliver and set up the device, train parents, and bill payers for the episode, under S9098 where that is what payers pay [assumption A1] or under E0202 where it is not. Treats the file's premise that the binding constraint is the service model claim 13unconfirmed as the thing to own.
Ship the differentiator, not the garment: an OEM radiometer and dose-record module into a cleared LBI wearable, neither of which claims dosimetry claim 2verified, claim 47unconfirmed.
Bypass the rental channel: contract with whoever bears the cost of the avoided readmission, and the device travels with the record. Under per-case DRG payment that party is the payer or a capitated system, not a fee-for-service hospital [assumption A4].
Four new assumptions, each written back to the candidate as unverified (claims 68-71). The fourteen assumptions the 2026-09-03 build declared are already on the candidate as claims 50-63, each attempted by the Verifier on 2026-09-29 and tagged unconfirmed; this rebuild cites them as claims rather than re-declaring them, because re-appending them would duplicate lines the Verifier has already worked.
| # | Assumption | Falsifier | Owner |
|---|---|---|---|
| A1 | State Medicaid programs and commercial plans in the largest US birth states pay newborn home phototherapy predominantly under the per-diem service code S9098, which bundles equipment rental with nursing and blood draw, rather than under the equipment code E0202 (claim 68unverified) | Read the current DMEPOS and home-health fee schedules of the California, Texas, Florida and New York Medicaid programs for E0202 and S9098 lines, and the home-phototherapy medical policies of the two largest commercial plans in each; revealed-behaviour twin: which code an operating home-phototherapy provider actually bills in each state | Reimbursement analyst |
| A2 | A payer that prices E0202 as a monthly rental pays one full rental month's allowable for a home phototherapy episode of 2-4 days, rather than a prorated or per-day amount (claim 69unverified) | The DME MAC supplier manual rule on rental-month billing for capped-rental items, plus the rental-unit definition in each target state's Medicaid DMEPOS provider manual | Reimbursement analyst |
| A3 | HCPCS E0202 has no row in the CMS Physician Fee Schedule RVU file, so no practice-expense RVU carries the cost of a device billed under it (claim 70unverified) | python3 -m connectors rvu E0202 --jurisdiction US against the cached PFS RVU file, re-run by the Verifier | Verifier |
| A4 | A newborn phototherapy readmission is paid to the hospital as a per-case DRG by state Medicaid programs and most commercial plans, so the avoided cost accrues to the payer, not the hospital, outside capitated or value-based contracts (claim 71unverified) | The inpatient payment method (APR-DRG or other) in the target states' Medicaid hospital payment manuals, plus a commercial contract template or a health system's payer-mix disclosure on newborn admissions | Reimbursement analyst |
Every figure with no evidence behind it, gathered as work items.
/market-model idea-004 is the cheaper next pass: it is the only process in the repo
that will file the missing legs as research rather than restate them.
unconfirmed on the Verifier's attempt, none moved.
