Best Practices for Managing HMO Prior Authorizations in SNFs

HMO prior authorizations can determine whether a skilled nursing facility gets paid smoothly—or spends the next several months fighting a denial.

The clinical team may believe the resident needs skilled nursing care. The facility may have a bed available. Nursing and therapy may already be preparing to provide treatment.

But if the HMO requires prior authorization and the approval is missing, late, incomplete, or inconsistent with the dates billed, the revenue cycle is already at risk.

For nursing home owners, CFOs, administrators, and billing managers, prior authorization should therefore be treated as a revenue-cycle function, not simply an administrative task.

At Zeebra Group, we help nursing homes manage HMO billing, authorizations, denials, appeals, accounts receivable, and managed-care follow-up. In practice, the strongest authorization departments are usually not the ones making the most phone calls. They are the ones that know exactly which resident needs action, what the deadline is, and who owns the next step.

Why HMO Prior Authorizations Matter So Much in SNFs

HMO plans commonly use networks, utilization-management processes, and prior authorization to manage covered care.

For skilled nursing facilities, HMO prior authorizations can affect:

• Admission
• Covered dates
• Level of care
• Continued stay
• Clinical documentation
• Discharge planning
• Claim submission
• Denials
• Appeals
• Cash collections

For Medicare Advantage specifically, CMS has established significant prior-authorization protections and decision-time requirements. Impacted payers generally must respond within 72 hours for expedited requests and seven calendar days for standard requests, while acting sooner when the patient’s condition requires it. Centers for Medicare & Medicaid Services

The facility may be delivering hundreds or thousands of dollars of care every day.

That makes an unresolved authorization a financial exposure—not simply an unfinished administrative task.

1. Verify the Exact HMO Plan Before Admission

The first best practice is accurate payer identification.

Do not stop when admissions sees the name of a large insurance company.

One payer may operate multiple products with different:

• Networks
• Authorization rules
• Provider portals
• Review vendors
• Coverage criteria
• Claim procedures
• Appeal processes

Before admission or as early as possible, confirm:

• Plan name
• Exact product
• Member ID
• Effective date
• SNF benefit
• Facility network status
• Prior-authorization requirement
• Utilization-management contact
• Portal
• Applicable payer instructions

A facility can communicate with the right insurance company but still work under the wrong product rules.

Create a Standard Verification Checklist

Every managed-care admission should answer four questions:

Who is the payer?

What exact product does the resident have?

Is the SNF in network?

What authorization is required before or during the stay?

Those answers should reach authorization staff and billing—not remain only in admissions.

2. Do Not Rely on a Verbal Assumption of Approval

One of the most dangerous phrases in managed-care billing is:

“They said it should be approved.”

That is not the same as having a documented authorization.

Whenever applicable, the facility should capture:

• Authorization number
• Approved service
• Approved dates
• Approved level of care
• Number of approved days
• Payer contact or portal record
• Conditions attached to approval

If final approval is still pending when care begins, that status should be visible.

Leadership should know when the facility is providing care without confirmed reimbursement.

That does not necessarily mean the resident should not be admitted. It means the financial exposure should be understood rather than discovered later.

3. Use One Central HMO Authorization Tracker

A major cause of authorization failures is fragmented information.

One employee has notes in a spreadsheet.

Another has messages inside a payer portal.

The DON has a fax.

Billing has an authorization number in the resident account.

No one has the full picture.

A central tracker should include:

The most important column may be Next Action.

“Pending” is not an actionable status.

Better:

“Clinical update submitted October 8; standard request due by October 15; Maria to check portal October 13.”

Now everyone understands what happens next.

4. Track the Internal Deadline, Not Just the Expiration Date

Suppose the current authorization expires Friday.

If the team begins the continued-stay process Friday afternoon, it has already created unnecessary risk.

Work backward instead.

For example:

Authorization ends Friday

→ Clinical documentation ready Wednesday

→ Continued-stay request submitted Wednesday

→ Status checked Thursday

→ Escalation initiated if needed

The exact schedule will vary by payer.

The principle does not:

The authorization expiration date should not be the staff action date.

Your internal deadline should come earlier.

This gives staff time to manage missing documentation, payer questions, portal problems, or additional review requests before approved coverage ends.

5. Reconcile Authorization Against the Daily Census

This is one of the most effective controls for HMO prior authorizations.

Compare:

current HMO residents

against

current valid authorizations

Look for:

• Resident with no authorization
• Authorization expiring soon
• Approved dates that do not match census
• Resident whose plan changed
• Hospital return with an old authorization
• Resident remaining after approved days ended
• Incorrect authorized level of care

A simple exception report can catch these problems days before billing discovers them.

Pay Special Attention to Hospital Returns

Hospital transfers and returns can create authorization confusion.

Do not automatically assume the existing approval continues unchanged after the resident returns.

Confirm what the specific plan requires and update the authorization record accordingly.

6. Make Clinical Documentation Part of the Authorization Workflow

Authorization staff cannot work independently from nursing, therapy, and other clinical teams.

The plan may request documentation supporting continued skilled care, including:

• Current clinical condition
• Nursing needs
• Therapy progress
• Functional status
• Physician information
• Continued skilled need
• Discharge barriers
• Current treatment plan

When authorization staff spend half a day chasing documents internally, the payer’s deadline does not stop.

Create an Internal Documentation Standard

Define:

• Who supplies the documentation
• What information is normally required
• How the authorization team requests it
• How quickly clinical staff should respond
• Where the final documentation is stored

The goal is not to produce unnecessary paperwork.

It is to ensure that payer requests do not become emergencies every time an authorization approaches expiration.

7. Use the 2026 Prior-Authorization Decision Timeframes

The current federal rules give SNFs a useful framework for monitoring prior-authorization requests.

For impacted payers, including Medicare Advantage organizations, prior-authorization decisions for medical items and services generally must be made as quickly as the patient’s condition requires and no later than:

• 72 hours for expedited requests
• 7 calendar days for standard requests

CMS also requires impacted payers to provide a specific reason when a prior-authorization request is denied. Centers for Medicare & Medicaid Services

For SNF authorization teams, that means a request should not remain indefinitely labeled:

“Waiting on insurance.”

Track:

• Submission date
• Standard or expedited status
• Expected response date
• Actual response date
• Escalation date

If the applicable timeframe passes without resolution, the account should move into an escalation workflow.

8. Understand Medicare Advantage Continuity-of-Care Protections

There are also important Medicare Advantage protections that authorization teams should understand.

CMS requires coordinated-care plans to provide at least a 90-day transition period when an enrollee undergoing an active course of treatment changes to a new Medicare Advantage plan. During that transition period, the new plan may not require a new prior authorization for that active course of treatment.

CMS also requires an approved prior authorization for a course of treatment to remain valid for as long as medically reasonable and necessary under applicable coverage criteria. Centers for Medicare & Medicaid Services

These rules do not eliminate the need for careful eligibility and payer verification.

They do mean SNF teams should understand current Medicare Advantage protections rather than relying only on payer practices learned several years ago.

9. Review Every Significant Authorization Denial

A denial should trigger review—not an automatic write-off.

This is especially important in skilled nursing.

HHS OIG reported in 2026 that the 19 Medicare Advantage organizations it examined collectively denied 12% of SNF admission authorization requests during June 2024.

Only 18% of those denied requests were appealed.

However, among the SNF denials that were appealed, the Medicare Advantage organizations overturned 95% in favor of the enrollee. OIG said the exceptionally high overturn rate raised concerns about some initial denial decisions. OIG HHS

That does not mean every denial should automatically be appealed.

It means every significant denial deserves a meaningful review.

Ask:

• What exactly was denied?
• What reason did the payer provide?
• Were the correct clinical criteria applied?
• Was all required documentation submitted?
• Is additional documentation available?
• What is the appeal deadline?
• How much revenue is at risk?
• Is reconsideration or appeal appropriate?

The denial is a decision point.

It is not necessarily the end of the account.

10. Track Appeals With the Same Discipline as Authorizations

Once an appeal is filed, it needs its own workflow.

Track:

• Denied amount
• Denial reason
• Date received
• Appeal deadline
• Appeal submission date
• Supporting documents
• Confirmation number
• Payer response date
• Current status
• Final decision
• Amount recovered

Never allow the final note to be:

“Appeal submitted.”

That explains what happened yesterday.

It does not tell you what happens tomorrow.

CMS also maintains formal Medicare Advantage reconsideration procedures for adverse organization determinations, so appeal deadlines and procedures need active tracking rather than informal follow-up. Centers for Medicare & Medicaid Services

Separate Authorization Denials by Root Cause

Suppose management sees:

Authorization denials: $185,000

That number alone is not enough.

Break the denials down into categories such as:

• No authorization obtained
• Authorization expired
• Continued-stay request late
• Medical necessity
• Missing documentation
• Wrong plan
• Incorrect approved dates
• Wrong level of care
• Payer processing issue

Then track both:

number of claims

and

dollars at risk

The most frequent denial is not always the most expensive denial.

If one workflow problem produces three $50,000 denials, it may deserve more executive attention than twenty $300 denials.

Calculate Revenue at Risk

A useful authorization metric is:

Expected daily reimbursement × days without confirmed authorization

For example:

Expected HMO reimbursement: $650 per day

Pending days: 6

Revenue at risk:

$3,900

That might not seem enormous for one resident.

Across twenty residents:

$78,000

Now the authorization problem becomes much easier for leadership to understand.

A dashboard that displays only “17 pending authorizations” does not communicate financial urgency nearly as well as:

$96,000 of care currently has unresolved authorization.

Do Not Let the Authorization Department Work in Isolation

Strong HMO prior authorizations require several departments to coordinate.

Admissions

Confirms the exact payer and product.

Authorization Team

Obtains and tracks approval.

Nursing and Therapy

Provide clinical documentation.

Billing

Confirms authorized dates match claim dates.

Accounts Receivable

Works authorization-related denials and appeals.

Administration

Escalates significant payer problems.

Weak handoffs between those departments create AR.

Strong handoffs prevent it.

Connect Authorization With Billing Before Claim Submission

Before an HMO claim leaves the facility, reconcile:

payer → member ID → authorization → census → claim dates

All five should agree.

Suppose authorization covers October 1 through October 10.

The claim contains October 1 through October 14.

Submitting first and asking questions afterward can create partial denial, claim holds, additional correspondence, and weeks of unnecessary AR.

Resolve the discrepancy first whenever possible.

Build a Payer-Specific HMO Authorization Matrix

HMO requirements vary.

Create an internal payer matrix containing:

• Plan
• Product
• Portal
• Authorization contact
• Utilization-management vendor
• Initial authorization process
• Continued-stay process
• Documentation requirements
• Appeal process
• Escalation route
• Network information
• Important operational notes

For a broader explanation of managed-care billing, see HMO Billing Explained for Nursing Homes and Long-Term Care Facilities. This article is already live on the Zeebra Group site. Zeebra Group

The authorization matrix should be a living operational document.

If employees do not trust it because it has not been updated in two years, they will stop using it.

Know When a Third-Party Utilization Management Vendor Is Involved

Some Medicare Advantage organizations use contractors to process prior-authorization requests.

OIG’s 2026 SNF review found meaningful differences depending on who processed the requests. The contractor naviHealth processed half of the SNF admission requests reviewed and denied 14%, compared with 11% for requests processed internally by MA organizations and 9% for other contractors. Among appealed naviHealth SNF denials, 97% were overturned. OIG HHS

For an SNF, the operational lesson is simple:

Do not track only the insurance company.

Track who is actually reviewing the authorization when a separate utilization-management entity is involved.

Monitor Authorization Performance by Plan

A monthly dashboard should show:

• Total authorization requests
• Pending requests
• Average turnaround time
• Denial rate
• Authorization-related AR
• Appeal rate
• Appeal overturn rate
• Revenue recovered
• Requests exceeding expected timeframes
• Common denial reasons

Then compare plans.

If one HMO consistently generates more authorization problems than another, management should see the pattern.

That information can guide staffing, escalation, contracting conversations, and admission planning.

Hold a Short Daily Authorization Huddle

Facilities with significant managed-care census can benefit from a brief daily review.

Focus only on exceptions:

• New HMO admissions
• Pending authorizations
• Authorizations expiring soon
• Continued-stay requests due
• Denials requiring immediate action
• Missing clinical documentation
• High-dollar revenue at risk

This does not need to become a 45-minute meeting.

Ten focused minutes can prevent days—or weeks—of avoidable AR.

How HMO Prior Authorizations Affect Collections

Better authorization management improves the entire revenue cycle.

When approvals are obtained, documented, and monitored correctly:

• Fewer claims sit on hold
• Clean claim performance improves
• Authorization denials decline
• Appeals decrease
• AR ages more slowly
• Billing spends less time on preventable rework
• Cash reaches the facility faster

That is why authorization and collections should not be managed as completely separate processes.

Conclusion: HMO Prior Authorizations Need a Revenue-Cycle Mindset

Strong management of HMO prior authorizations comes down to visibility, timing, and ownership.

Know the exact plan.

Verify authorization requirements early.

Document the approval.

Track the internal deadline before expiration.

Connect authorization with clinical documentation.

Reconcile approvals against census.

Review denials.

Track appeals.

Measure revenue at risk.

And make sure every pending request has one person responsible for the next action.

For nursing home owners, CFOs, administrators, and billing managers, the most important authorization question is not:

“Did somebody submit the request?”

It is:

“Is every day of care we are currently providing financially protected?”

That is the difference between authorization administration and revenue-cycle management.

FAQ

What are HMO prior authorizations in skilled nursing facilities?

HMO prior authorizations are approvals that an HMO may require before covering SNF admission, continued skilled care, or another covered service. Requirements depend on the resident’s specific plan and applicable coverage rules.

How quickly must Medicare Advantage plans decide prior-authorization requests?

Impacted Medicare Advantage organizations generally must issue decisions as quickly as the patient’s condition requires and no later than 72 hours for expedited requests or seven calendar days for standard requests. Centers for Medicare & Medicaid Services

What should an SNF authorization tracker include?

Track the payer, exact plan, member ID, authorization number, approved service, start and end dates, approved days, next review date, submission date, status, responsible employee, and next action.

When should an SNF begin a continued-stay authorization request?

The facility should establish an internal deadline before the current authorization expires. This creates time to gather documentation, submit the request, answer payer questions, and escalate problems before coverage ends.

Should SNFs appeal HMO authorization denials?

Each denial should be reviewed based on clinical support, payer rules, applicable deadlines, and financial exposure. OIG’s 2026 review found that 95% of appealed SNF admission authorization denials in its sample were overturned, which makes careful denial review particularly important. OIG HHS

What happens when a Medicare Advantage resident changes plans during ongoing treatment?

CMS requires coordinated-care plans to provide at least a 90-day transition period when a member undergoing an active course of treatment switches to a new Medicare Advantage plan. During that period, the new plan may not require a new prior authorization for that active course of treatment. Centers for Medicare & Medicaid Services

How do HMO prior authorizations affect nursing-home AR?

Missing, expired, delayed, or mismatched authorization can prevent claim submission, cause denials, require appeals, and increase days in AR. Strong authorization tracking helps prevent those delays.

Does Zeebra Group help manage HMO prior authorizations?

Yes. Zeebra Group supports nursing homes with HMO prior authorization tracking, continued-stay follow-up, Medicare Advantage billing, authorization denials, appeals, HMO AR, and revenue-cycle reporting.
