BOAS Surgery Cost and the Congenital Clause

Two clinics publish their prices for surgery on the same two structures in a flat-faced dog's airway. A Georgia practice charges $1,872.50. A university teaching hospital publishes $3,500 to $5,500 for the same broad operation, on a price table stamped June 2023.

Neither figure is a mistake. The two are not buying the same list of items, and one of them is already three years old on the day you read it.

Whether any particular dog should have this surgery is not a question this page goes near — that is settled in an exam room, by a veterinarian who has examined the animal. What follows is the two documents that decide the money: the price sheet, and the policy paragraph that can delete the entire reimbursement without ever using the word brachycephalic.

$1,872.50 and $5,500 are both real prices for this surgery

Four sources publish their numbers. All four pages were read on 4 September 2026; the dates on the figures themselves are a separate matter, and one of them is not 2026.

Read the right-hand column before the middle one. The two cheaper entries buy two procedures. The Washington fee adds a third "as indicated." The Illinois estimate is a diagnostic workup with a surgery inside it.

How often does the third one turn out to be indicated? In a case series of 80 dogs operated on for BOAS between 2018 and 2022, published in Frontiers in Veterinary Science in 2025, 65 dogs had everted laryngeal saccules and 62 of those (95.38%) had a sacculectomy. Forty-eight of the 80 — 60.00% — had all three procedures: alarplasty, staphylectomy and laryngeal sacculectomy. That population was already booked for surgery at a referral hospital, so it says nothing about flat-faced dogs generally. It does suggest that in a room where this operation is happening, the conditional line is frequently not conditional.

The Georgia page carries a smaller lesson about which numbers on a price page are load-bearing. Three different savings figures sit on it. The page title, the line that shows in a browser tab and in search results, reads "Save $100 With Our Bulldog Package." The heading directly above the prices reads "Save $55 With Our Bulldog Package." And the prices themselves — $1,391 for the palate and $535 for the nares, against $1,872.50 for the two together — subtract to $53.50. Only the last of the three is built from figures that will appear on an invoice. The two that are advertised are the two you cannot check.

Illinois is also the outlier on dating. Its table of surgical estimates ends with the line "Update June 2023," so $3,500–$5,500 is a three-year-old published figure that was still the posted figure in September 2026. It is evidence that a teaching hospital priced this work in that range, not a number anyone is bound by now. That is a different problem from the distance between the low and high figure inside any one estimate, which is about what might happen to your animal rather than about what year it is.

The flat fee assumes one night

Every one of those figures is priced on an ordinary recovery. The Austin sheet says so outright: its estimates cover the charges "expected for ordinary cases," and complications "will likely increase the total surgery fees."

The 80-dog series gives the shape of the exception. Median postoperative hospital stay was one night, with a range of 0 to 11. Postoperative complications occurred in 25 of 80 dogs (31.25%). Four dogs (5.00%) needed a temporary tracheostomy. Illinois, describing its soft tissue service in general rather than this operation specifically, states that "On average soft tissue patients stay in hospital 2-3 days post surgery," with incisions re-evaluated 10 to 14 days later.

So the distance between a $3,000 flat fee and the bill that prints is not surgeon time. It is nights, oxygen, and an airway that needed more help than the schedule allowed. Ask what an additional night is billed at before anything gets signed at drop-off.

One sentence on the Illinois page is worth carrying into your own planning wherever the surgery happens: "You will need to leave a deposit of the low end of your estimate when you leave your pet for care. The remainder of the bill must be paid at the time of discharge." That is the structure an emergency clinic uses when it asks for money at the front desk, published here by a teaching hospital: the low figure is what is payable on the way in, and the timing of the rest is fixed at discharge.

The clause that removes the payout never says "brachycephalic"

Now the other document.

Nationwide's plan restrictions page, read 4 September 2026, lists excluded conditions plan by plan, and it is not shy about naming things. One of the two Major Medical listings on that page spends a single bullet numbering twenty conditions in a row: renal dysplasia, cystine or urate urolithiasis, collapsed trachea, distichiasis, entropion, primary glaucoma, progressive retinal atrophy, cataracts in dogs under seven years of age unless secondary to injury or diabetes, von Willebrand's disease, and eleven others. Another bullet names hip dysplasia, elbow dysplasia, patellar luxation and osteochondritis dissecans. Airway surgery in a flat-faced dog appears in none of it.

It is reached by two short lines instead. From the second of those Major Medical listings:

Congenital anomalies or developmental defects

Hereditary disorders

Search that page for brachycephalic, nares or palate and nothing comes back at all. Search for congenital and there are the two lines that decide the bill.

The wording is not even uniform inside the page. Two listings both labelled Major Medical Plan sit one after the other, each with its own sample policy, and they differ. The first of the two attaches a rider to the hereditary line — "Hereditary disorders, but we do provide limited additional coverage for specified ineligible conditions" — which is not the same sentence as a flat exclusion, and sends you to a specified-conditions benefit rather than to zero. Feline Select reaches the same ground with different nouns: "Congenital disorders or developmental defects" and "Hereditary conditions."

Whole Pet and Whole Pet with Wellness carry neither line. The Modular plan's exclusion list mentions "Congenital & Hereditary coverage" only in passing, as one of the coverages a buyer selects, which tells you the category is sold there as a component rather than assumed. One insurer, one web page, four different treatments of the same category. The one governing you is the plan name printed on your declarations page, and that name was chosen once, at purchase.

One syndrome, filed under two body systems, on one page

Nationwide also publishes the list behind those two lines. Document 21WEB8488, List of Congenital & Hereditary Conditions, posted 30 September 2021, devotes its final page to congenital disorders and developmental defects sorted by body system. The respiratory row reads:

Respiratory System (Airways and Lungs): Brachycephalic airway syndrome; Stenotic nares; Elongated soft palate; Everted laryngeal saccules; Tracheal hypoplasia

Every component of the operation described above, itemised. Then, six rows further down the same table, the musculoskeletal row names "Brachycephalic syndrome" a second time.

The congenital-versus-hereditary distinction looks like the fork in the road, since the two words have genuinely different meanings and some plans exclude one without the other. The document closes that idea off in a footnote: "Some conditions listed in this document may also be considered hereditary in certain breeds." The same footnote block adds that the list "is not meant to be all-inclusive," and that these conditions "are not covered under some Nationwide pet insurance policies, even if they are not listed here." A list that is explicitly not exhaustive is not a coverage boundary. It is an illustration of one.

Which reframes the question. It is not is this condition congenital or hereditary — the contract has already answered that in its own way. It is does my plan exclude either category.

The contract that calls both of them illnesses

The opposite treatment exists, and it is worth seeing in an actual form rather than a marketing summary. Figo's policy form IAIC FPI POL OH 0824 — the OH is the state, the 0824 the August 2024 edition — is underwritten by Independence American Insurance Company and published in full in Figo's library of state policy documents. Definition 21 says:

Congenital Anomalies or Disorders and Hereditary Disorders are considered Illnesses under this Policy.

Covered, then — subject to everything that governs an illness. That form applies a 14-day waiting period from the pet's original start date for illnesses and 30 days for orthopedic illnesses, and allows a waiver: a veterinarian must perform a full examination within 7 days of the start date, the owner pays for that exam, and the completed waiver form has to reach the insurer within 7 days of the effective date.

Two more lines from the same form change the arithmetic on this bill specifically. Exclusion 7 removes "Examinations or fees for similar services performed by a Veterinarian or a Veterinary Provider in the course of treating an otherwise eligible condition," itemised down to "in-person consultations, health inspections, office visit charges, office calls, after-hour fees, emergency fees, clinical fees, referral fees, or recheck fees," unless the optional Office Visit and Exam Fees coverage was bought. Exclusion 8 removes rehabilitation and physical therapy on the same terms. The Austin price sheet requires a consultation before it will schedule either airway procedure; Illinois builds the exam into its estimate. Under that policy, the consultation is a charge you carry unless a rider elected at purchase says otherwise.

The model act standardised the words, not the coverage

Both insurers above are using vocabulary somebody else wrote. The NAIC Pet Insurance Model Act (Model Law 633, Summer 2022 edition) defines the terms in Section 3:

"Congenital anomaly or disorder" means a condition that is present from birth, whether inherited or caused by the environment, which may cause or contribute to illness or disease.

"Hereditary disorder" means an abnormality that is genetically transmitted from parent to offspring and may cause illness or disease.

Section 3 also requires an insurer using those terms to adopt these definitions and print them in the policy. One paragraph earlier sits the sentence people skip:

Nothing in this Act shall in any way prohibit or limit the types of exclusions pet insurers may use in their policies or require pet insurers to have any of the limitations or exclusions defined below.

The model act makes the words mean the same thing everywhere. It does not make them buy anything. Section 4 requires disclosure of whether a policy excludes preexisting conditions, hereditary disorders, congenital anomalies or disorders, or chronic conditions — a labelling rule, not a coverage rule.

Where it has been enacted, the disclosure has an address. California Insurance Code section 12880.2 requires a summary titled "Insurer Disclosure of Important Policy Provisions," reachable through a link on the main page of the insurer's website and delivered with the policy in at least 12-point type; section 12880 carries near-identical definitions, as amended by Stats. 2024, Ch. 612, effective 1 January 2025. Near-identical, not identical: California's congenital wording reads "may cause or otherwise contribute to illness or disease," one word longer than the model's. Adoption varies by state, so check your own insurance department's site for what your insurer had to file rather than assuming California's rule travels.

Snoring is a clinical sign to the chart, whatever it is to the owner

Even under a policy that covers the category, a claim can be refused without the exclusions list being involved at all, on the ground that the condition was already on file.

The model act's preexisting definition reaches a condition where, prior to the effective date or during a waiting period, "based on information from verifiable sources, the pet had signs or symptoms directly related to the condition for which a claim is being made." Not diagnosed. Not treated. Signs.

Here the breed literature and the contract language meet in an uncomfortable place. The VetCompass study of French Bulldogs under primary veterinary care in the UK, published in Canine Medicine and Genetics in 2021, is usually quoted for its odds ratios: stenotic nares 42.14 (95% CI 18.50–95.99) and BOAS 30.89 (20.91–45.64) against dogs of other breeds, drawn from a 2016 UK population of 905,544 dogs under veterinary care. The one-year prevalence figures printed beside them point somewhere rather different, and are worked through in the breed-level budgeting piece.

The sentence that matters for an insurance application is further down, in the discussion. Signs such as snoring and snorting, the authors write, get attributed to being "normal for the breed" — and they cite work in which 58% of owners of BOAS-affected dogs failed to recognise that their dog had a breathing problem at all, alongside a French Bulldog study in which 60% could not recognise the clinical signs.

An owner who does not think snoring is a problem does not raise it, and does not put it on an application. A veterinarian writing up a puppy visit may still write it down. That is the same mechanism that turns an offhand chart note into a permanent exclusion in any other condition, and it bites harder here because the median French Bulldog in that study was 1.51 years old. The records are short, and whatever is in them was written recently.

The window is the first 14 or 30 days, and it closes quietly

All of this is decided before there is a bill. The category treatment is fixed by the plan name at purchase. The waiting period runs from the effective date. The waiver, where one exists, runs on two seven-day clocks — the examination, then the signed form — and both start at the beginning of the policy. By the time a surgical estimate is in your hand, those three are settled, and the only live variables are on the price sheet.

So the useful sequence runs opposite to the one people follow. Before the policy: search the PDF for congenital, hereditary and developmental, read the definitions section governing those words, then check whether your state requires the insurer to publish a disclosure summary. Before the surgery: ask which components the published figure covers, what an extra hospital night bills at, and whether the consultation is billed apart from the procedure.

Breed-level budgeting arithmetic only starts working once those answers exist. An odds ratio tells you what to expect. It does not tell you who pays, and that second question is answered by two lines on a web page that never mention the dog.
