Hospice MAC filing tends to get treated like a year-end chore until the calendar gets tight and someone realizes the real issue is not whether a package was sent, but whether the Medicare Administrative Contractor will accept it. That distinction matters. CMS requires freestanding hospices to submit an electronic cost report and supporting documentation to the MAC, and a successful submission through the Medicare Cost Report e-Filing system begins the MAC’s 30-day acceptance process rather than ending the work (CMS Chapter 43 instructions, CMS MCReF overview). (cms.gov)
For hospice leaders, that is where the pressure usually shows up. Finance may believe the numbers are done. Operations may believe the census data is stable. Billing may assume claims history tells the whole story. Then the MAC looks for the actual filing package, the correct form, the right signature, the matching electronic file, and the supporting detail behind bad debts, related-party costs, and overhead allocation. What sounds administrative is really a reimbursement, compliance, and recordkeeping exercise rolled into one annual event (CMS Chapter 43 instructions, Home Health Agency/Hospice Acceptability Checklist). (cms.gov)
What Hospice Medicare Administrative Contractors (MAC) Filing Actually Means
In plain terms, hospice MAC filing usually refers to submitting the annual Medicare cost report package to the contractor that handles hospice Medicare administration for the provider’s jurisdiction. CMS explains that MACs are the contractors that administer the Medicare fee-for-service program, and Chapter 43 of the Provider Reimbursement Manual uses that same MAC structure as the filing destination for the hospice electronic cost report and supporting documentation (CMS overview of MACs, CMS Chapter 43 instructions). (cms.gov)
That is important because MAC filing is not the same thing as routine claim submission, and it is not the same thing as hospice quality reporting. A hospice may be current on claims and still have a weak cost report process. It may also be current on quality reporting and still miss cost report requirements. CMS currently states that HQRP compliance depends on fulfilling HOPE, CAHPS Hospice, and administrative claims requirements, and CMS public reporting materials note that HOPE replaced HIS for public reporting beginning October 1, 2025 (CMS Hospice Quality Reporting Program, CMS hospice public reporting updates). For a broader view of those separate reporting streams, readers may also find our overview of item-set reporting under HQRP and our discussion of claims-based quality measures helpful. (cms.gov)
The First Question Is Which Form Applies
A surprising amount of hospice filing trouble starts with a basic classification issue. CMS is clear that Form CMS-1984-14 is for freestanding hospices. Provider-based hospices do not use that form. Hospital-based hospices must use Form CMS-2552, skilled nursing facility-based hospices must use Form CMS-2540, and home health agency-based hospices must use Form CMS-1728 (CMS Chapter 43 instructions). (cms.gov)
That distinction is more than labeling. It affects which worksheets apply, how overhead gets allocated, where the hospice activity sits inside the larger provider structure, and how the MAC evaluates the submission. A hospice that is separately certified can still be provider-based for cost reporting purposes, so the filing team has to confirm the reporting structure before it starts assembling the package. We have seen that one classification decision shape the rest of the engagement, because every downstream schedule depends on getting that first choice right (CMS Chapter 43 instructions, CMS hospices certification overview). (cms.gov)
The Filing Deadline Is Straightforward, but Acceptability Is the Real Test
CMS says hospice cost reports are due on or before the last day of the fifth month following the close of the reporting period, and Chapter 43 notes that the only provision for an extension is the one identified in 42 C.F.R. § 413.24(f)(2)(ii) (CMS Chapter 43 instructions, 42 C.F.R. § 413.24). (cms.gov)
That means a hospice with a December 31 fiscal year end is generally looking at a May 31 filing deadline, not a vague spring target. It also means leadership should stop thinking of the filing date as the day the team starts compiling data. By then, the statistical records, accruals, related-party support, and reconciliation work should already be substantially complete. CMS’s MCReF guidance adds another practical point: for fiscal year ends on or after December 31, 2017, providers can file 100 percent of the Medicare cost report package electronically through MCReF, and successful submissions are immediately received by the MAC so the 30-day acceptance review can begin (CMS MCReF overview). (cms.gov)
That acceptance concept matters more than many teams expect. In Medicare cost reporting, “filed” and “acceptable” are not interchangeable words. A hospice can transmit something on time and still face rejection if the submission package does not satisfy the MAC’s intake standards (Home Health Agency/Hospice Acceptability Checklist). (cms.gov)
What the MAC Looks for Before It Accepts the Report
The MAC’s front-end review is procedural, but it is not superficial. CMS’s acceptability checklist asks whether the provider submitted the electronic cost report using a CMS-approved vendor and current specifications, whether the file passes all Level I edits, whether a print image file was included, whether Worksheet S has a valid digital signature or original ink signature from the administrator or chief financial officer, whether the encryption code on the signed certification matches the electronic file, and whether the settlement summary on the signed certification agrees with the Medicare cost report produced from the electronic file. For applicable cost reports, the checklist also asks for supporting bad debt documentation (Home Health Agency/Hospice Acceptability Checklist). (cms.gov)
The practical lesson is simple. MAC filing is not only about having defensible numbers. It is also about having a package that is technically consistent from signature page to encrypted file. CMS further instructs the contractor to contact the provider within 24 hours of rejection to notify the provider of the rejection and any payment suspension, if applicable. That is why a hospice can feel blindsided even when the accounting itself was mostly right. The defect may be in format, matching, or missing support rather than in the trial balance (Home Health Agency/Hospice Acceptability Checklist). (cms.gov)
What the Hospice Cost Report Actually Captures
The hospice cost report is more detailed than many people remember. CMS introduced Form CMS-1984-14 to replace the prior hospice form and summarized the structure this way: Worksheet S-2 carries reimbursement questionnaire data, Worksheet A separately identifies general service costs, Worksheets A-1 through A-4 identify direct patient care services by level of care, Worksheets B and B-1 allocate general service costs by level of care, Worksheet C calculates per diem costs by level of care, and the F series reports hospice financial data (CMS Chapter 43 instructions). (cms.gov)
That design tells you what CMS wants to see. The MAC is not just asking whether total expenses tie to the general ledger. It is asking how those costs move through the hospice, how overhead is assigned, and what the economics look like by level of care. Worksheet C, for example, calculates the average cost per diem by level of care, which means the quality of daily census statistics and cost allocation methods matters directly to the finished report (CMS Chapter 43 instructions). (cms.gov)
Related organizations and home office allocations also need careful treatment. CMS devotes Worksheet A-8-1 to costs from related organizations and home office arrangements, and the instructions reference the rule that related-party costs are includable only at the cost to the related organization, subject to the prudent buyer limitation for comparable services or supplies (CMS Chapter 43 instructions). (cms.gov)
Just as important, CMS says providers receiving Medicare reimbursement must maintain adequate financial and statistical records that can be verified by qualified auditors, and the cost data must generally be based on the accrual basis of accounting. That is the reason strong hospice MAC filing starts months before submission. The cost report is built on the year’s recordkeeping habits, not on a single week of cleanup work in the filing window (CMS Chapter 43 instructions, 42 C.F.R. § 413.20). (cms.gov)
Where Hospices Usually Get Into Trouble
Most filing problems are ordinary, which is exactly why they are so persistent. A hospice may wait too long to reconcile census days by level of care. Contract labor may be coded broadly during the year and only sorted later, when memories are weaker and documentation is harder to recover. Home office allocations may arrive late or without enough support. Related-party transactions may be booked cleanly for financial statement purposes but not presented the way Medicare cost reporting expects. None of those issues is dramatic, but each one can weaken the package the MAC receives (CMS Chapter 43 instructions, Home Health Agency/Hospice Acceptability Checklist). (cms.gov)
Bad debt support is another frequent pressure point. CMS’s acceptability checklist explicitly calls for a detailed bad debt listing that corresponds to the amount claimed in the cost report for applicable areas. If that support is not ready when the package is filed, the hospice may have a technically complete-looking report that still fails the acceptance test (Home Health Agency/Hospice Acceptability Checklist). (cms.gov)
This is why we usually frame hospice MAC filing as a cross-functional project rather than a finance-only assignment. The numbers may live in accounting, but the support usually lives across billing, clinical operations, payroll, vendor management, and leadership approvals. When those groups hand work to one another late, the MAC sees the result as an inconsistent filing package. When they work from the same calendar and the same source documentation, the final report tends to hold together much better (CMS Chapter 43 instructions, Home Health Agency/Hospice Acceptability Checklist). (cms.gov)
Why the Filing Still Matters in a Changing Hospice Environment
It is easy to think of the cost report as a legacy process because hospice payment is not settled the same way some older Medicare models were. That is the wrong instinct. CMS says the information reported on Form CMS-1984-14 supports management of federal programs, and the agency’s hospice cost report data page says the HCRIS release includes FY 2015 through present hospice cost reports and is normally updated quarterly. In other words, the data does not disappear into a closed file cabinet. It becomes part of the system CMS and outside analysts use to understand the economics of hospice care (CMS Chapter 43 instructions, CMS hospice cost report data). (cms.gov)
The current payment environment makes that even more relevant. CMS’s FY 2025 hospice update states that the hospice payment update for FY 2025 is 2.9 percent, that the 2025 cap year runs from October 1, 2024 through September 30, 2025, and that the hospice cap amount for that cap year is $34,465.34. The same CMS update also notes that failure to meet hospice quality reporting requirements reduces the market basket update by 4 percentage points starting with FY 2024 (CMS MLN Matters MM13707). That makes a disciplined compliance calendar more valuable, not less. For readers comparing these moving parts, our discussion of cap exposure in hospice covers another piece of the reimbursement picture. (cms.gov)
Building a Filing Process That Holds Up
A better hospice MAC filing process usually starts with admitting that the cost report is assembled all year long, whether the hospice intends that or not. Every monthly close either preserves the detail CMS will want later or erodes it. Every late reclass entry, vague contract expense code, unsupported related-party invoice, or unreconciled census report makes the filing window harder than it needs to be. Since CMS requires adequate, auditable financial and statistical records and expects an electronic package that passes technical edits, the smartest approach is to build toward the filing every month rather than reconstruct it after year-end (CMS Chapter 43 instructions, Home Health Agency/Hospice Acceptability Checklist, CMS MCReF overview). (cms.gov)
In practical terms, that means keeping the chart of accounts aligned to the cost report structure, preserving statistical support by level of care, documenting home office and related-party allocations when they occur rather than months later, and reviewing the certification and electronic file controls before the submission week arrives. It also means treating the MAC filing calendar as part of the hospice’s broader Medicare reporting calendar, alongside quality reporting and cap monitoring, but not confusing one requirement with another (CMS Chapter 43 instructions, CMS Hospice Quality Reporting Program). (cms.gov)
Conclusion
Hospice MAC filing is at its core a test of readiness. The form matters, the deadline matters, and the electronic package matters, but the deeper issue is whether the hospice has maintained the kind of records and internal discipline that Medicare cost reporting expects. When that foundation is in place, filing becomes a controlled process instead of a year-end scramble. Click the button below to schedule a time to chat. (cms.gov)
