What a diagnostic actually looks like when it lands.

This is a complete phase-one report for a five-site dermatology group. It is eleven pages of findings, evidence and sizing — and the practice it describes has never existed for a single day.

Read this part first.

Northwood Dermatology Partners is invented. So are its five locations, its eleven clinicians, its payers, and every number below. We built it specifically to be shown.

The reason is the same promise you would be buying. We cannot show you a real client's report — it is not ours to show — and when the report is yours, it will not be ours to show either. No client of ours appears in a case study, a pitch deck, a conference talk or a website, named or thinly disguised. That is not a policy we can suspend for a good prospect, which means a specimen is the only honest way to answer “what do I actually get?”

So: the company is fiction. The structure, the vocabulary, the evidence standard, the way a finding is sized, and above all what we refuse to conclude — those are exactly what arrives.

The question this answers

Is there enough here to justify a full review? Not “is anything wrong” — something is always wrong. The question is whether what is wrong is concentrated enough, and large enough, to be worth four more weeks of anyone's attention.

Short answer for Northwood: yes, but narrowly. Four of the six findings below sit in one place — the gap between what a drug costs the practice and what the practice is paid for it. That concentration is the argument for phase two. Had it been six unrelated findings of this size, our recommendation would have been to fix them and not commission us again.

What we were given

  • Charge, payment and adjustment detail from Modernizing Medicine EMA, all five sites, 24 months — 96,412 encounters
  • Remittance files as received from the clearing house, unaggregated
  • Executed payer contracts and fee schedules, all five sites
  • Distributor invoices for buy-and-bill product, 24 months
  • Dispensary and aesthetics point-of-sale export, which shares no key with the clinical system
  • Provider compensation model and the productivity report it is calculated from
  • General ledger, trial balance and the chart of accounts as actually used

Seven sources. Two of them — the distributor invoices and the point-of-sale export — had never been read against the clinical data, because nothing joins them automatically. Four of the six findings are in that join.

Findings

Sized to an order of magnitude, annualized, and stated as a range. A diagnostic that quotes a recovery to the dollar is quoting a number it cannot have.

Finding 01 · Payer contracting

The same procedure is reimbursed five different ways inside one group.

Northwood's five sites joined at different times, and four of them kept the payer contracts they arrived with. For the group's twelve highest-volume CPT codes, the allowed amount from the same payer differs by site — in one case by 31% for an identical procedure performed by clinicians who now share a compensation pool.

How this was found: executed fee schedules keyed to charge detail by site and CPT, then compared against realized payments in the remittance files rather than against the contract. Two sites are being paid below their own contracted rate, which is a separate and more recoverable problem than the contracting spread itself.

This is not a negotiation failure. Nobody ever had all five contracts open at once.

Indicative annual value$310,000 – $520,000
ConfidenceFirm
Phase two wouldRate-load all five contracts and quantify underpayment per payer
Finding 02 · Buy-and-bill

Drug is bought at one price and reimbursed against a formula that does not know that price.

Northwood purchases, holds and administers biologic and injectable product worth $6.1M a year, and is reimbursed against a published payment formula. The spread between acquisition and allowable is positive on most product and materially negative on four items, which between them account for roughly 9% of drug volume. The practice carries the inventory risk in between on its own balance sheet.

How this was found: distributor invoice lines matched to administration records by NDC and date, then to the remittance for that encounter. This join did not exist. It is the single most valuable thing we built during the diagnostic.

Nobody is doing anything wrong here. The purchasing decision and the reimbursement consequence are simply made by different people, months apart, in systems that do not speak.

Indicative annual value$240,000 – $390,000
ConfidenceFirm
Phase two wouldRebuild the join as a standing monthly control
Finding 03 · Wastage

Reimbursable discarded drug is being absorbed instead of billed.

Where a single-dose vial is larger than the dose administered, the remainder is reimbursable when billed with the JW modifier and documented. Across 24 months the modifier appears on 11% of eligible administrations at one site and on essentially none at the other four.

How this was found: administered units compared against vial sizes on the distributor invoice, then against modifiers present on the submitted claim. The site that bills it correctly is the one whose lead nurse previously worked in oncology infusion.

The constraint is documentation, not billing. Phase two would test whether the documentation to support the modifier exists before recommending it be claimed — billing it without support is a worse outcome than not billing it.

Indicative annual value$85,000 – $140,000
ConfidenceProbable
Phase two wouldTest documentation sufficiency before claiming anything
Finding 04 · In-office pathology

A global charge is assumed where the payer's place-of-service rules say otherwise.

Northwood reads its own dermatopathology at two sites. Claims are submitted globally. For two payers representing 23% of that volume, the published rules for the place of service recorded require the technical and professional components to be split, and the global submissions are being reduced on adjudication rather than denied — which is why this has never appeared in the denial rate anybody watches.

How this was found: a reduction pattern in the remittance detail that never becomes a denial. Aggregated denial reporting cannot see it. This is a fair example of why we read remittances as received rather than as summarized.
Indicative annual value$190,000 – $300,000
ConfidenceFirm
Phase two wouldConfirm per-payer rules and quantify the recoverable lookback
Finding 05 · Retail and dispensary

$2.4M of retail stock is counted at the till and never inventoried.

Cosmeceutical, injectable and optical stock is recorded when it sells and when it is ordered, and never counted in between. Shrinkage, expiry, staff purchase and a genuinely slow month are therefore indistinguishable from one another in the accounts. Gross margin on this line is reported at 61% and is not calculable from the available data.

How this was found: purchase volume against sales volume by SKU, with no counted balance at either end. The gap is real; its composition is unknown, and we will not guess at it.

We are not saying anything is being taken. The most common cause of a gap this shape is expiry on slow-moving stock. It is stated here because an uncounted $2.4M is a control weakness whatever its cause, and because you cannot rule anything in or out until it is counted.

Indicative annual value$120,000 – $260,000
ConfidenceIndicative
Phase two wouldEstablish a counted baseline; re-measure at 90 days
Finding 06 · Compensation

The productivity ranking measures what clinicians do, not what they earn.

Provider compensation is calculated from a productivity report that does not separate ancillary work. Two clinicians ranked in the bottom third of the group carry the highest proportion of pathology and dispensary-attached encounters, and contribute more margin than three clinicians ranked above them.

How this was found: encounter-level margin reconstructed from the same joins built for findings 02 and 04, then compared against the ranking in use.

This one recovers nothing. It is here because a compensation formula that mismeasures contribution eventually costs a group the wrong clinician, and that is more expensive than everything else on this page. It is also the finding most likely to be resisted, which is worth knowing before it is raised.

What this report does not say

A diagnostic that overstates its own authority is worse than no diagnostic. So, explicitly:

Who reads which part

The same report, three audiences. A document that only works for one of them stalls in the room where it is presented.

Signs it off

Practice administrator or CEO, with the managing physician on clinical scope. They read the question, the summary table and the refusals — roughly two pages.

Is likely to resist

Physician owners whose compensation formula finding 06 decomposes. Worth deciding how that is raised before the meeting, not during it.

Already knows

The revenue cycle lead, who can usually name the problem sites before we open anything. Findings 01 and 04 will not surprise them; the evidence for them is what they have lacked.

Your version of this costs $12,000.

Same structure, your registers, about two weeks. If the answer is that nothing is concentrated anywhere interesting, the report says so and we do not propose a review — a worse outcome for us and a perfectly good one for you, and the reason this is worth commissioning rather than taking our word for it.

And it stays yours. Your report is never shown to anyone, in any form, named or disguised — which is why the one above had to be invented.
