Strengthen PDPM and HIPPS accuracy, control consolidated-billing exposure, support IRF and LTCH compliance, and keep post-acute claims moving from assessment to payment.
Post-acute care billing covers institutional services delivered after or instead of a traditional acute hospital stay, including:
These settings are not reimbursed through one common model.
SNFs use the Medicare Patient-Driven Payment Model (PDPM) within the SNF PPS for covered Part A stays. IRFs use the IRF prospective payment system and IRF-PAI assessment data. LTCHs operate under the LTCH PPS and related payment rules. Swing beds follow rules tied to the facility type and Medicare program requirements.
Post-acute RCM is therefore assessment-driven, classification-driven, and extremely sensitive to dates, coverage status, patient characteristics, and claim sequencing.
Post-acute revenue depends heavily on the connection between clinical assessment and billing classification.
Key components include:
Key areas include:
Key areas include:
These rules require billing, coding, clinical assessment, utilization, and finance teams to remain aligned.

Institutional revenue loss often begins upstream—in documentation, classification, charge capture, claim structure, status, payer logic or posting—before it appears as a denial or aged balance.
SNF reimbursement can be affected when MDS data, clinical category mapping, NTA comorbidities, SLP characteristics, nursing classification, functional scoring, or assessment timing do not accurately reflect the resident's documented condition. The objective is accurate PDPM classification—not maximizing a HIPPS code beyond what the MDS and record support.
For beneficiaries in a covered Part A SNF stay, the SNF is generally responsible for a broad package of services, with specific services excluded from consolidated billing and separately payable. CMS updates the exclusion lists. Failing to identify whether an outside service is included or excluded can result in vendor disputes, duplicate billing, denials, or facility liability.
CMS requires IRFs to meet the 60% Rule for payment under the IRF PPS. MACs determine compliance on an annual basis for the cost-reporting period. This is a facility-level classification/compliance issue, not something that should be manipulated claim by claim. Census and diagnosis data should be monitored accurately so leadership can identify compliance risk early.
For Medicare classification purposes, an LTCH generally must maintain an average inpatient length of stay greater than 25 days. This is a facility-level average requirement. It should never be treated as a reason to keep an individual patient hospitalized longer than medically necessary. The revenue-cycle role is to monitor classification and payment implications, not influence clinical discharge decisions for reimbursement.
Post-acute claims are highly date-sensitive. Coverage periods, qualifying hospital stays where applicable, benefit-day tracking, interrupted stays, payer changes, and authorization requirements can all affect claim outcome. ---
CareMedox review can cover:
CareMedox's role is to connect assessment, claim data, payer adjudication, and AR—not to interfere with clinical decision-making.
---
CareMedox works the root cause and the affected inventory together so the institution is not forced to repeat the same correction claim after claim.
MDS and claim data are reconciled to identify unsupported discrepancies, missed documented characteristics, and classification errors before or after billing.
Current CMS exclusion logic and the resident's covered-stay status are checked before treating outside services as separately billable.
ALOS and applicable LTCH payment rules are monitored as revenue-cycle indicators without using reimbursement to drive patient length of stay.
Eligibility, benefit status, authorization, dates, and claim sequencing are checked before balances age into avoidable denials.
High-value post-acute balances are prioritized by payer, denial reason, filing/appeal deadline, and recoverability.
These are CareMedox operating targets after onboarding and workflow stabilization—not guaranteed payer outcomes.
98%+ first-pass clean institutional claim target
Under 2% preventable front-end / clearinghouse rejection target
Approximately 5–6% overall denial-rate target
95%+ target for assessment-to-claim discrepancy identification within records included in the agreed audit workflow
Active 60/90/120+ AR prioritization
These are operating targets, not guaranteed payer outcomes.
Certified coding review is connected with senior revenue-cycle operations, detailed reporting, aging control and transparent reconciliation.
CareMedox connects certified coding review with senior professionals experienced in claim scrubbing, payment posting, denial handling, reconciliation, and AR.
The institutional workflow is built around a 98%+ first-pass clean-claim target after onboarding and stabilization.
CareMedox aims to control avoidable denials close to the source rather than building an ever-larger downstream denial department.
Where CareMedox has access to the required registration, coding, CDM, and payer information, the goal is to drive preventable clearinghouse/front-end rejects below 2%.
Aging is prioritized by financial impact, filing/appeal deadline, denial reason, and recoverability.
Hospital reporting should show payer behavior, denial root cause, claim status, payment variance, posting corrections, aging, and recovery—not just a monthly collection total.
The senior CareMedox team has experience across more than 15 platforms and can work with different clearinghouses.
Where a claim becomes nonrecoverable solely because of CareMedox negligence, the CareMedox TFL accountability policy applies according to the executed agreement and applicable Medicare-fee-schedule basis.
The audit is tailored to the facility type and focuses on what is wrong, why it is happening, what is financially exposed and what needs to change upstream.
Request a 30-Day Post-Acute RCM AuditCareMedox keeps billing, coding, claim, payer and AR work aligned while clinical or legal judgment remains with the institution's authorized personnel when required.
CareMedox focuses on accurate classification based on the MDS and medical record. Supported patient characteristics should not be missed, but unsupported classification should never be added for payment.
During a covered Part A SNF stay, the SNF has broad consolidated-billing responsibility, subject to specific CMS exclusions. CareMedox can help screen services and claims against the applicable rules.
No. Medicare's greater-than-25-day measure is an average inpatient length-of-stay classification requirement for the LTCH. It should not be used to hold an individual patient longer than medically necessary.
Yes. CareMedox can segment older AR by payer, benefit status, denial reason, appeal deadline, and recoverability and actively work 60/90/120+ balances. ---
Move between related facility workflows without leaving the institutional RCM cluster.
Post-acute RCM becomes expensive when assessment data, coverage rules, claim classification, and payer adjudication stop matching.
A shorter first step when you want to discuss a billing, RCM, AR, denial, reporting or payer-workflow concern without completing the full inquiry form.
