Reordering Worksheet B After a Clinic Acquisition
Northgate Hospital is a 175-bed acute care hospital with a December 31 fiscal year end. Its Worksheet B step-down has run in the same order for a decade: Administrative and General on accumulated square footage, Plant Operation and Maintenance on square footage, Laundry and Linen on pounds, Dietary on meals, Medical Records on records processed, then the patient care areas. This year the hospital acquired a 45-physician multi-specialty group and certified it as a provider-based department occupying 92,000 square feet in an on-campus medical office building that had never been in the square footage statistics. Clinic staff now eat in the cafeteria and the hospital launders clinic linens. The CFO proposes three changes to protect reimbursement: (a) keep the 92,000 square feet out of the A&G statistic, (b) move Medical Records ahead of Administrative and General, and (c) switch A&G to a salaries statistic because payroll data is easier to pull than measured square footage.
1. Evaluate each of the CFO's three proposals against Medicare cost-finding requirements.

(a) Excluding the 92,000 square feet is not defensible. Once the clinic is a provider-based department, its costs and statistics belong to the hospital's single cost report. Overhead allocated through A&G must reflect the space the clinic actually occupies. Keeping it out understates overhead in a cost center that generates Medicare utilization and pushes that overhead onto inpatient areas - a misallocation reviewable under 42 CFR 413.24, which requires adequate data and accurate allocation of costs to the services that caused them. The MAC will find the square footage in the building survey.
(b) Moving Medical Records ahead of A&G inverts the logic. Order changes are permitted, but the sequence must reflect the flow of services. A center that serves many other centers goes early; a center consumed mainly by patient care departments goes late. Medical Records is used overwhelmingly by patient care areas, so placing it first would have it absorb nothing and distribute to A&G, which does not describe any real relationship.
(c) A change of statistical basis is allowed only if it is the more accurate and objective measure. Salaries can be a defensible basis for administrative services, but convenience is not a rationale. If square footage is the better measure of the A&G relationship, the change is a reimbursement-driven reclassification and should not be made - and a basis cannot be swapped year to year without explanation.
2. Explain how moving a cost center earlier or later in the step-down changes Medicare reimbursement, and how a defensible order is established.

Mechanics. In a step-down, each center's accumulated cost - direct cost plus everything allocated in from centers above it - is distributed once, downward, and never receives cost from a center below it. A center placed early has its cost spread over many centers, including other overhead centers, so part of it travels through them before reaching patient care; its own Medicare utilization ratio no longer controls the outcome. A center placed late keeps its cost concentrated among the remaining recipients, so its reimbursement share is a blend of those recipients' shares.
Because of that, the question 'does moving Medical Records earlier raise payment' has no abstract answer. Model it: compare the Medicare utilization ratios of the centers that would receive the shifted cost. If earlier placement pushes cost into high-Medicare-share centers, reimbursement rises; if into low-share centers, it falls. A quick spreadsheet of the affected cost centers, run both ways, answers the question and doubles as audit documentation.
A defensible order allocates the most general, most widely consumed services first (A&G, plant, laundry) and the most patient-specific services last, based on what each center actually provides to the others. The order should be stable over time and must never be justified by its reimbursement effect.
3. What documentation and consistency obligations attach to the change, and can it be applied to prior years?
Read the worked answer
Documentation. Retain the underlying statistics, their source, the date compiled, and the person responsible, plus a short memo explaining why the acquisition changes the facts and why the order and basis remain appropriate. The workpapers must reconcile to Worksheet A and B totals. Disclose the change if the MAC requests an explanation; volunteer it in the audit binder rather than waiting to be asked.
Consistency. The MAC will accept a reasonable, documented, consistently applied method and will challenge a method that moves with the reimbursement result. This year the underlying facts genuinely changed - new square footage, new meals, new pounds of linen - so some statistics will move legitimately. Show the factual cause, not the dollar goal.
Prior years. A methodology change applies to the year it is implemented and is not retroactive; adopting a better basis does not by itself reopen settled years. The distinction that matters is between a different-but-reasonable method (prospective only) and a method that was actually wrong (correction runs through reopenings for each affected year inside the three-year window, not through a catch-up adjustment in the current report). The hospital cannot fix a decade of square footage errors by inflating or deflating this year's statistic.
