What people’s searches for a diagnosis tell the agencies that publish the numbers

1. What the published figures say, and what they miss

72 conditions: 17 with a published burden figure (16 federal, 1 only a peer-reviewed analysis: Long COVID), 55 without one yet. 3 of the 17 have a published annual figure, 2 of them federal; every absence is shown, never filled.

No published annual figure we could find: 69 conditions, each named on the page at /policy and in the JSON at /api/policy.

We have not found a published federal annual figure for these 55 conditions. That is a statement about what we could find, not a claim that none exists anywhere. If you know of one, say so and we will price it and cite it. Each figure is shown apart and is never added to anyone’s ledger, and figures of different kinds are not ranked against each other.

What no expenditure file counts

A medical expenditure figure is what was paid for care a person received. [MEPS HC-251 documentation; MEPS survey background] By that definition it cannot hold time spent: visits, waiting, travel; paid work missed; unpaid care from family or friends; care you went without. People searching for a diagnosis ranked those burdens themselves:

Reading the register…

2. Where published figures are disputed

Every line of a ledger carries a Right and a Wrong. A Wrong is bound to the one published row it is about, so the count can be read by the agency and the file that published the number. Cells under 11 are not shown.

Reading the register…

“Routable”, not “routed”: the corrections file names the office, the file and the row, and nothing has been sent to any agency.

3. What this could change

Existing federal rules and programs this evidence speaks to. Each says what the evidence shows today and what a larger N would let an agency do. None of this has happened.

1. The No Surprises Act good-faith estimate

   Today: Every Wrong a person sends names the one published figure it is about, and may carry what they say they actually paid. With more answers: With enough answers per service, CMS could see which services people most often say cost them far more than the published federal amount, and look there first for estimates that are missing or wrong.

   A person who is uninsured or pays for their own care is owed a good-faith estimate, and a bill at least $400 over it can be disputed through patient-provider dispute resolution.

   Today: Every Wrong a person sends names the one published figure it is about, and may carry what they say they actually paid. The register counts how many carry an amount, by agency and fee schedule; the amounts are never summed or printed.

   With a larger N: With enough answers per service, CMS could see which services people most often say cost them far more than the published federal amount, and look there first for estimates that are missing or wrong. That comparison has not been made.

   • Source 2. CMS, Dispute a medical bill (2026).Did your provider charge at least $400 more than your good faith estimate? You may be eligible to dispute your bill.

2. Hospital price transparency

   Today: 255 of the 274 published figures in this tool carry the CPT or HCPCS code the federal schedule prices, the same codes a hospital file must list. With more answers: An agency could set what people say they paid beside the hospital’s posted charge and the Medicare amount for the same code, and see where the three part ways, service by service.

   Every hospital must publish its standard charges for all items and services online, in a machine-readable file that carries the billing code for each.

3. NIH RECOVER, the long COVID research initiative

   Today: People searching for a diagnosis rank five burdens, and four of them (time, paid work missed, unpaid care, care gone without) are in no expenditure file. With more answers: A ranking with a large N, read by sex and by age at onset, would give researchers a patient-ranked list of which long COVID burdens to measure.

   Congress gave NIH $1.15 billion in December 2020 to study the long-term effects of COVID-19; NIH runs that work as the RECOVER Initiative.

   Today: People searching for a diagnosis rank five burdens, and four of them (time, paid work missed, unpaid care, care gone without) are in no expenditure file. The ranking is published with its N, and by sex only once a group holds 11 answers.

   With a larger N: A ranking with a large N, read by sex and by age at onset, would give researchers a patient-ranked list of which long COVID burdens to measure. Today the N is too small to support that.

4. HHS on the burden long COVID puts on people

   Today: The ledger prices a person’s own visits and tests from federal files, and counts, apart from any dollar, the care they went without, the time and the work lost. With more answers: HHS could report the burden on individuals as people rank it, beside the published spending figures, instead of spending alone.

   The 2022 presidential memorandum asked HHS to advance understanding of the health and socioeconomic burdens on individuals with long COVID, and HHS names reduced work and economic burden today.

   With a larger N: HHS could report the burden on individuals as people rank it, beside the published spending figures, instead of spending alone. That needs many more answers than the register holds.

5. The cost of Lyme disease, as HHS’s own reports asked for it

   Today: The two Lyme blood tests are priced from the CMS Clinical Laboratory Fee Schedule: CPT 86618 at $17.03 and CPT 86617 at $15.49, each with its file and row. With more answers: With Lyme searches itemized line by line and enough of them, HHS could set the cost of a Lyme diagnostic search, as people lived it, beside the published per-case estimates.

   HHS’s Tick-Borne Disease Working Group asked for studies of the total cost of illness of tick-borne diseases, beginning with Lyme, and the Lyme human-centered design report made for the HHS LymeX effort recommends a cost-of-care resource.

   Today: The two Lyme blood tests are priced from the CMS Clinical Laboratory Fee Schedule: CPT 86618 at $17.03 and CPT 86617 at $15.49, each with its file and row. Lyme is one of the conditions in section 1.

   With a larger N: With Lyme searches itemized line by line and enough of them, HHS could set the cost of a Lyme diagnostic search, as people lived it, beside the published per-case estimates.
