When a skilled nursing facility in Boise changes hands, Idaho Medicaid keeps paying the buyer on the seller's numbers. The buyer gets the previous owner's rate, inflated forward, and keeps getting it until the buyer has a cost report of its own that meets the state's rate-setting criteria. A purchase price built on what a new operator plans to do with costs, staffing or census is really a bet on what the old operator already reported. In Idaho, that reported base was cut twice in 2025.
This rule is part of the Idaho Medicaid "Additional Terms – Nursing Facilities" provider agreement. The Idaho Department of Health and Welfare reissued it under Medicaid Information Release MA26-18, dated August 6, 2026, and it took effect September 7, 2026. Under the agreement, a provider is deemed to accept an amendment once the 28-day notice period runs. Every Ada County nursing facility with a Medicaid provider agreement is now operating under this version, and so is every buyer stepping into one.
The clause that sets a buyer's first rate
Section A-4.12 of the updated agreement, titled "Treatment of a Change of Ownership," puts it in one sentence:
"New providers resulting from a change in ownership of an existing facility will receive the previous owner's rate, inflated forward to the appropriate cost reporting year, until such time as the new owner has a cost report that qualifies for the rate setting criteria established under these rules."
"Until such time" can run for years. Section A-4.17 says cost report periods shorter than 184 days will not be used for rate setting. After a change of ownership, the last cost report of 184 days or more stays in use until the new owner files one that covers at least 184 days or is based on the new fiscal year. A buyer whose closing leaves a short stub period before fiscal year-end gets no rate credit for that stub. The seller's last full report keeps setting the rate.
How the inherited rate runs its course
The agreement lays out the sequence one step at a time:
- At closing. The new owner receives the prior owner's rate, inflated forward to the appropriate cost reporting year.
- The seller's paperwork. If the outgoing operator is being reimbursed on a retrospective basis, it must file an adjusted-period cost report no later than 60 days after the change, so a final program settlement can be computed. Operators reimbursed on a prospective basis, or receiving a new provider rate, do not file a closing cost report. The Department may also require an appraisal at the time of a change in ownership.
- Short periods do not count. Any cost report period under 184 days is excluded from rate setting.
- The third rate year. If the new owner is still on the prior owner's rate in a third rate year, the rate for that year becomes the higher of the inflated prior owner rate or the statewide median rate for that nursing facility class.
- The discretionary exception. If the Department finds a facility operationally or financially unstable, it may negotiate a reimbursement rate different from the one in effect.
Read in order, the steps show that the seller's operating record sets the buyer's Medicaid revenue for a period measured in rate years. Only in a third year does the median floor raise a below-median rate. Even then, the new owner still has not earned a rate built on its own costs.
The base being inherited was cut twice in 2025
If Idaho rates were rising, inheriting one would be a minor detail. They have been falling. Medicaid Information Release MA25-17 put in place a 4% reduction across provider types, explicitly including nursing facilities, effective September 1, 2025. The Idaho Capital Sun reported that the department expected the cut to save $36.8 million in fiscal 2026. As of August 2025, the department projected Medicaid budget growth at 19%, compared with the 8% lawmakers had assumed when they wrote the budget.
Skilled Nursing News reported that the September cut came on top of a 3% reduction on July 1, 2025, which it described as a 7% cut to long-term care reimbursement in 60 days. The same article quotes Cascadia Healthcare CFO Steve LaForte, whose company operates 25 facilities in Idaho. LaForte tied the decline to the Legislature's 2018 Medicaid budget freeze, which had no carve-out for nursing homes. The article cites a decline from $277 per day in 2018 to $252 per day once the first of the 2025 cuts took effect on July 1, 2025.
The state has also signaled the cut may outlast fiscal 2026. In October 2025, the Idaho Capital Sun reported that, as part of Gov. Brad Little's directive to make 3% agency budget cuts permanent, the state planned to keep the 4% Medicaid provider rate cut for another year, through fiscal 2027. Under the state's long-term care provider handbook, nursing facility reimbursement is a facility-specific per diem, and rate updates require legislative approval.
Combine that with A-4.12 and the result is plain. A Boise facility bought in late 2026 brings with it a prior owner rate set after the 2025 reductions, with a planned extension of the 4% cut reported for fiscal 2027. The buyer cannot reset that rate until it has filed its own qualifying cost report.
Payer mix makes the stakes larger. Robert Vande Merwe, executive director of the Idaho Health Care Association, told Idaho Reports that Medicaid pays for about 67% of nursing facility care in the state. He warned that the reduction could lead facilities to accept fewer Medicaid residents, or none. At that payer mix, the inherited rate does not adjust a small share of revenue. It sets most of it.
Low occupancy carries over with the rate
The seller's census history comes along with the seller's rate. Section A-4.14 sets an occupancy adjustment factor. If a facility's average occupancy is below 80% of capacity, total property costs, excluding costs paid under the property rental rate, are prorated as if occupancy were 80%. The gap between actual occupancy and 80% is multiplied by total fixed costs, and that amount is treated as nonallowable. Property taxes and property insurance are reimbursed per diem outside the direct and indirect cost limits, but they are also subject to minimum occupancy levels.
Capacity is measured generously against the operator. It is the greater of the largest number of beds licensed during the reporting period or during calendar year 1981, with exceptions for converted space and for newly constructed facilities that entered the Medicaid program after January 1, 1982. If the seller's last qualifying cost report reflects a year of soft census, that disallowance is part of the rate the buyer starts with, whatever the buyer's lease-up plan says.
Building new does not get around the median
Some buyers look at a discounted inherited rate and consider building instead. The agreement prices that path too. Facilities constructed on or after July 1, 2023 are reimbursed at the median rate for their type for the first four full years of operation, reduced by 10%, with the median reset each July 1. Added beds at an existing facility face a similar cap. The facility's rate is limited to a bed-weighted average of its current prospective rate and the lesser of two figures, the median for that facility type reduced by 10% or the facility's own prospective rate reduced by 10%.
| Path to a Medicaid rate in Idaho | Rate basis under the September 2026 agreement | When the operator's own costs take over |
|---|---|---|
| Acquire an existing facility | Prior owner's rate, inflated forward; in a third rate year, the higher of that or the class median | Once the new owner files a qualifying cost report of 184 days or more |
| Build a facility on or after July 1, 2023 | Median for the facility type, reduced by 10%, reset each July 1 | At the next July 1 after four full years of operation |
| Add beds to an existing facility | Bed-weighted blend of current rate and the lesser of median less 10% or own rate less 10% | Built into the facility's bed-weighted limit |
For an acquired facility, the starting point depends entirely on where the seller stood. A facility whose last full cost report sits above the median carries that advantage to the buyer. One sitting below it carries that discount, and the median floor does not apply until the third rate year.
What the rule puts on the diligence list in Ada County
The Boise-area nursing facility market includes facilities with specialized units. Idaho DHW currently lists Cascadia of Boise and Shaw Mountain of Cascadia in Boise, Creekside Transitional Care and Rehabilitation in Meridian, and Meadow View and Orchards of Cascadia in Nampa as Behavioral Care Units. The agreement includes separate care cost limit categories for free-standing and hospital-based behavioral care units. For a facility like these, the relevant median is a class median, not a single statewide figure.
Under the agreement's terms, the documents that shape an Idaho buyer's early Medicaid revenue include:
- The seller's most recent cost report covering 184 days or more, along with its income statement, balance sheet, schedule of patient days, and schedule of private patient charges
- Average occupancy against licensed capacity as the 80% adjustment measures it
- Whether the seller is reimbursed on a retrospective or prospective basis, which determines whether a closing cost report and final settlement apply
- The facility's class and where its rate sits against that class median
- The fiscal year-end and its timing relative to closing, which decides whether the buyer's first period reaches 184 days
One structural change is further off than many 2025 underwriting models assumed. House Bill 345, passed in March 2025, directs Idaho Medicaid to move from fee-for-service to managed care, but DHW now lists the shift as delayed to January 1, 2030. The blackout period for the managed care RFP begins December 1, 2026, and the RFP is expected to post later in 2027. For any hold period that starts this year, the cost-report rate system in the September 2026 agreement is the system that will pay the buyer, probably through most of the rate years discussed above.
