Contract 8577, United HealthCare Services: medical third party administration and pharmacy benefit management

Three of five models read this as bad; GPT 5.6 Sol and Gemini 3.1 Pro called it partial because page 10 warrants that services will be performed with the care of a prudent claims administrator or fiduciary and page 34 names United a fiduciary for initial claim determinations and first level appeals. We re-read pages 10, 26 and 34. The fiduciary role is confined to claim decisions, page 26 disclaims any duty beyond claim administration, and nothing requires loyalty to the plan when United sets MAC lists, tiers drugs, or keeps spread, purchase discounts and float interest. There is no conflict disclosure duty and no disgorgement remedy, so the contract permits the self dealing the model clause by Mark Cuban and collaborators exists to prevent. The prudent administrator warranty is a real but narrow counterweight, which is why confidence is moderate.

Four of five models read this as partial; Gemini 3.1 Pro called it missing because no clause requires a complete accounting of compensation. The text does disclose several revenue streams: the $2.00 per member per month consultant fee paid to Lockton through the pharmacy terms on page 67, access fees and marketing charges collected from network pharmacies on page 42, an affiliate transaction fee of 1% to 3% on provider payments on page 60, and the 80 percent medical rebate share on page 58. None of these come with totals, there is no disclosure of affiliate ownership touching plan claims, and no named officer certifies quarterly or annually that everything has been disclosed and remitted. The subject is addressed piecemeal, which is weaker than the model rather than absent.

All five models reached this verdict. The exhibit list on page 2 and the attachments to Exhibit D contain no schedule of owners, parents, subsidiaries, affiliates, group purchasing organizations, rebate aggregators, or mail and specialty pharmacies, and there is no duty to refresh ownership information after a change in control. The only affiliate references are the definitions on pages 41 and 42 that fold United affiliates into the home delivery and specialty pharmacy definitions, and the Form CIQ on pages 85 and 86 concerns conflicts with City officers rather than PBM ownership.

No verbatim quote is available for this clause.

All five models reached this verdict. The Rebate definition on page 41 is written by label and carve out rather than by economic function: money received for direct purchases, payments to a group purchasing organization, and payments for products, services, tools or data analytics are all written out of the definition, and Price Protection is defined separately. Page 66 then confirms that Manufacturer Administrative Fees sit outside the guaranteed rebate arrangement. Brand and generic status follow Medi-Span codes and MAC pricing is whatever United places on lists it controls. These definitions let manufacturer value be relabeled so it never reaches the pass through, which is the loophole the model contract by Mark Cuban and collaborators closes.

Three of five models read this as partial; GPT 5.6 Sol and Gemini 3.1 Pro called it bad because page 45 states that United retains affiliate purchase discounts and purchase rebates and does not pass them on. We re-read pages 41, 45, 64, 65 and 66. The City is promised a 100.0% share of defined Rebates with per script minimums, so the subject is addressed and money does flow, but the promise is narrowed from every side. Rebate excludes direct purchase money, group purchasing organization receipts and service payments on page 41, Manufacturer Administrative Fees are excluded on page 66, page 45 lets United pursue other manufacturer revenue and keep affiliate purchase discounts, and pages 64 and 65 exclude a long list of claim types. The first payment can arrive 210 days after the quarter and later payments within 90 days, not 30. Under the majority rule this is a weaker version of pass through rather than a contradiction, but the minority reading is strong enough that confidence is low.

All five models reached this verdict. Pages 41 and 42 make United affiliates network pharmacies in the home delivery and specialty channels, page 45 says those affiliates keep the purchase discounts and purchase rebates on drugs they buy, and pages 43 and 67 let United keep the difference between what the pharmacy is paid and what the City pays. Nothing invoices affiliate claims at acquisition cost plus a stated dispensing fee and there is no documentation default. Affiliate pharmacies are priced by average wholesale price discount with margin retained, the opposite of the model rule.

All five models reached this verdict. The pharmacy pricing on pages 63 through 69 is built entirely on average wholesale price discounts measured in the aggregate over a year, with no cap tied to a published benchmark or transparent cash price and no claim by claim test. The usual and customary charge defined on page 42 and the lesser of three rule on page 67 limit what a member pays at the counter, not what the plan pays, and no other section addresses a ceiling.

No verbatim quote is available for this clause.

All five models reached this verdict. Page 67 gives members half of what the model asks for: at a network pharmacy they pay the lesser of the discounted price, the pharmacy reported cash price or their cost share, so a member should not pay more through the plan than the counter price the pharmacy reports. The text says nothing about crediting a cash purchase made outside the benefit toward the deductible or out of pocket maximum, and nothing about accumulator adjustments against manufacturer assistance, so the protection is present but narrower than the model.

All five models reached this verdict. Page 41 allows multiple maximum allowable cost lists changed at United sole discretion, with no requirement that the same list govern what the City pays and what pharmacies are paid, no disclosure to the City, no update schedule and no pharmacy appeal path anywhere in the document. Combined with the retained spread language on pages 43 and 67, this is the two list structure the model clause exists to prevent.

All five models reached this verdict. Spread pricing is stated in plain words three times: page 43 for home delivery, retail and specialty, page 67 for mail order, specialty and retail drugs and services including dispensing fees, and page 69 again for specialty drugs. The model contract requires the plan to pay exactly what the pharmacy is paid plus a disclosed administrative fee. Here the City has no contractual way to learn what the pharmacy actually received, and page 43 also lets United keep the interest earned on claim funds between withdrawal and pharmacy payment.

All five models reached this verdict. The Rebate definition on page 41 writes anything a group purchasing organization receives out of the pass through, page 45 lets United pursue other revenue from drug manufacturers directly or indirectly, and the same page states that affiliate purchase discounts and purchase rebates are retained and not passed on. No clause allocates purchasing entity money to the City on any driver. The contract preserves exactly the purchasing entity revenue channel the model clause is written to capture.

Three of five models read this as partial; GPT 5.6 Sol and Gemini 3.1 Pro called it bad because page 44 gives United the final classification of every drug to a tier, weighing economic factors that expressly include available Rebates. We re-read pages 43 and 44. The City is named the ultimate decision maker on the design of its drug list and chooses among United lists, which is a real if limited sponsor role. The working levers stay with the vendor: United makes the final tier call, provides negative change notices only on request, withholds its utilization management criteria from the City and its vendors, and must approve any customization. No lowest net cost analysis or quarterly utilization management outcomes are promised. Under the majority rule this is sponsor control weaker than the model rather than its absence, and the minority reading is recorded here.

Three of five models read this as missing; GPT 5.6 Sol and Kimi K3 called it bad because page 44 lets United weigh available Rebates when it places a drug on a tier and page 65 lets United cut the rebate guarantee if the City deviates from the list. We re-read pages 44, 45 and 65. No clause states a lowest net cost standard for this plan, no annual comparison against United book of business is promised, and nothing requires disclosure when a drug is placed above a cheaper equivalent. The only mention of lower net drug cost is on page 65, where United reserves the right to change the arrangement if list changes made to lower net cost for its customers reduce rebates. Because the rebate factor on page 44 is one input to tiering rather than an affirmative permission to favor high rebate drugs, the majority treated the standard as absent rather than contradicted, and the minority view is recorded here.

Three of five models read this as bad; GPT 5.6 Sol called it partial because page 42 promises reasonable notice of material network changes, and Gemini 3.1 Pro called it missing because no clause speaks to clawbacks or any willing pharmacy terms. We re-read pages 41, 42 and 67. Page 42 makes United or its affiliate the exclusive provider of pharmacy benefit services, pages 41 and 42 place the United owned home delivery and specialty pharmacies inside the network, page 67 conditions every pricing guarantee on that exclusivity across retail, mail and specialty, and the same page lets United revise or revoke the pricing if the City hires a vendor that helps members find cheaper drugs or pharmacies. United may add or remove pharmacies at will and no clause makes adjudicated claims final or lets any willing pharmacy join. The text does more than stay silent; it builds in affiliate steering and penalizes the City for steering elsewhere.

All five models reached this verdict. Page 66 gives the City one market check during the three year pricing term, initiated in the third quarter after the first anniversary, run by a mutually agreed third party against at least four similar customers, and comparing aggregate value rather than claim level pricing. If the report shows more than three percent annualized savings against the median the parties only negotiate in good faith, with any change effective the following contract year and only if an amendment is signed 60 days ahead. There is no most favored customer promise and no meet, credit or release remedy, so the item is present but weaker than the model.

Three of five models read this as partial; GPT 5.6 Sol and Gemini 3.1 Pro called it bad because page 46 caps rebate review at the lesser of the top five agreements or agreements covering 75% of rebate revenue and forbids the auditor from copying or retaining any rebate document. We re-read pages 10, 42 and 46. A genuine audit right exists, with access to all of the City claims, and page 10 gives the City general access to books and records. But the auditor must be mutually agreeable and sign a United confidentiality agreement, United must agree to the place, time, type, scope and duration, the look back is 18 months, December and January are off limits, each period may be audited only once, the City pays, and routine reporting is limited to United standard online reports on page 42 with no pre adjudication access. Under the majority rule this is a constrained right rather than a denial, though the rebate copying ban brings it close to the line.

Three of five models read this as bad; Gemini 3.1 Pro and Kimi K3 called it partial because page 14 bars either party from selling, licensing or commercially reusing the other party confidential information. We re-read pages 14, 47 and 50. No clause makes the City the owner of its claims, eligibility, accumulator or rebate data, and there is no right to machine readable delivery on request. Page 50 lets United de-identify the City health data and use and disclose it on its own behalf, page 14 lets United answer post termination information requests at its discretion and for a fee, and page 47 limits transition help to twelve file transmissions in United standard format. The de-identified reuse right is exactly what the model clause forbids, so the majority verdict stands, with the page 14 restriction on selling confidential information noted as a partial counterweight.

Four of five models read this as partial; Gemini 3.1 Pro called it bad because the service guarantees are capped at flat amounts such as $11,000 per metric on page 61. Attachment D-6 does contain real guarantees: pharmacy discount, dispensing fee and rebate guarantees on pages 64 and 68 are customer specific and the shortfall is paid in dollars. But measurement and payment are annual rather than quarterly, the service guarantees are small capped credits often measured at the office or site level rather than on this plan, page 61 makes fee credits the City exclusive financial remedy, force majeure and legal change carve outs excuse United, and pages 65 to 68 give United many rights to revise or revoke the pharmacy guarantees. Guarantees exist but the remedies are weaker than the model.

Three of five models read this as partial; Gemini 3.1 Pro and Grok 4.6 called it missing because there are no liquidated damages and no two strikes exit anywhere in the document. We re-read pages 11, 46 and 61. Page 61 does convert missed guarantees into automatic fee credits without the City proving damages, which is the self executing half of the model design, and page 64 pays pharmacy shortfalls in dollars. The other half is absent: no liquidated damages for late reports, audit recoveries on page 46 require a mutually signed settlement, page 11 requires a 30 day cure before any termination for cause, and nothing gives the City a penalty free exit after a second material breach or a regulatory integrity event. Under the majority rule the automatic credit makes this weaker than the model rather than unaddressed.

Three of five models read this as bad; Grok 4.6 and Kimi K3 called it partial because page 16 says the contract can be modified only by a writing signed by both parties. We re-read pages 5, 16, 61 and 65 to 67. The bilateral rule on page 16 is real, but Exhibit A on page 5 lets the contractor change fees on 30 days notice at each renewal by delivering a replacement Attachment D-5, and change them at any time when the plan, the law or enrollment shifts by 10% or more, with the new fee effective retroactively; the City only recourse is to terminate. Page 61 lets United specify new guarantees and replace the exhibit, and pages 65 to 67 let United revise or revoke the pharmacy pricing on many triggers. Economic terms can move by notice, which is the harm the model clause exists to prevent, so the majority verdict stands.

Four of five models read this as bad; Grok 4.6 called it partial because page 11 lets either party terminate without cause after the initial term. We re-read pages 11, 55, 59 and 66. Convenience termination is available only after the three year initial term, on notice the text renders as thirty (120) calendar days. Leaving the pharmacy benefit early forfeits every pending and future rebate and cancels the minimum guarantee reconciliation on page 66, page 59 repeats the forfeiture for any exit other than for cause, page 45 lets United raise medical fees if pharmacy services end, and page 55 requires repayment of the administrative and wellness credits on early termination. Earned amounts are forfeited and no regulatory integrity event is a termination ground, which is the trap the model clause exists to prevent.

Four of five models read this as bad; Grok 4.6 called it partial because the specialty definition on pages 41 and 42 is functional, requiring at least three of eight clinical and handling criteria. The definition is the only element that meets the model. United designates the specialty drug list on page 46, may move a drug off specialty based on market conditions on page 68, prices specialty as an annual aggregate average wholesale price discount of 21.00% for listed drugs and 14.00% for unlisted drugs rather than as drug level ceilings, includes its own specialty pharmacy in the network, and on page 69 keeps the spread on every specialty claim. Specialty claims at the affiliate pharmacy are not priced at acquisition cost, which is the core of the model rule.

Four of five models read this as bad; Kimi K3 called it partial because page 14 carves out disclosures required by law including public records acts and page 13 says the public nature of material is judged under the Texas Public Information Act. We re-read pages 13, 14 and 58. Pricing, discounts, reimbursement terms, payment methodologies and compensation arrangements are defined as Confidential Information, the City may use them only for plan administration, United may require a confidentiality agreement before any disclosure, and on a public records request the City must give immediate notice and cooperate in seeking a protective order. That is a duty to help block release, not a clean carve out, so the guidance that a carve out letting the vendor seek to block release does not make a bad into a good applies. Page 58 promises language to support the City anti gag attestation, and nothing restricts pharmacies from telling members about cheaper options, but the fee pages themselves are stamped proprietary. The red flag is set.
