Common Credentialing Challenges for Home Health Providers

Key Takeaways 

• A nationwide CMS moratorium on new Medicare home health enrollments has been in effect since May 13, 2026, and it’s reshaping what “credentialing challenges” even mean for new agencies this year. 

• The CMS-855A application is where most home health credentialing challenges start, especially when the wrong form or an incomplete file gets submitted. 

• State surveys can’t happen until the Medicare Administrative Contractor gives initial approval of the 855A, which means one delay pushes back everything after it. 

• OASIS training gaps and inconsistent staff-level credentialing are two of the most common and most preventable sources of home health credentialing delays. 

• CAQH and commercial insurance credentialing run on a separate track from Medicare enrollment, and agencies often underestimate how much parallel work that creates. 

• Multi-state expansion multiplies every requirement instead of simplifying any of them, since each state sets its own survey, licensure, and Medicaid enrollment rules. 

• Agencies that build a credentialing calendar before problems appear consistently avoid the delays that catch reactive agencies off guard. 

Problems with getting home health care credentials rarely show up all at once. One is missing a signature, and another is a survey that can’t be scheduled yet. This goes on for a dozen small ones until an agency realizes it’s been waiting five months to bill Medicare for care it’s already given. 

The year 2026 has added something new to that picture. Because of a national enrolment freeze, new OASIS reporting rules, and increased CMS scrutiny of the home health industry, the licensing scene is very different from even a year ago. What used to be mostly a list of steps to follow has become a real piece of regulation, and the agencies that treat it as such are the ones that stay out of trouble. The first thing you need to do to get ahead of friction is to figure out where it comes from. 

Why Home Health Credentialing Challenges Keep Multiplying in 2026 

Home health is at an odd point in the road. Before an agency can bill a single commercial payer, it has to get a state license, Medicare credentialing at the federal level, and often accreditation from a private group like ACHC, CHAP, or the Joint Commission. There are different forms, due dates, and reviewers for each of these tracks. 

Because of this stacked structure, problems with home health credentialing get worse faster than they do in a normal doctor’s office. If one track is late because of something like a poll that needs to be moved, it doesn’t just slow down that track. It could stop accreditation, which in turn stops deemed status, which stops the CMS credentialing that all the other things depend on. 

The CMS Enrollment Moratorium Is Reshaping the Landscape 

This year, the biggest change that affects home health credentialing isn’t a paperwork issue. It’s the rule. On May 13, 2026, CMS put a six-month national ban on new Medicare enrollment for home health companies. This included new branch locations and office sites. This change affects all 50 states, the District of Columbia, and the territories. It also stops people from re-enrolling if they have made certain changes to their majority ownership within 36 months of their last enrollment. 

This is a very important difference. The ban only affects new applications to join Medicare. It does not affect agencies that are already approved and billing Medicare. Existing HHAs can keep doing their jobs, filing claims, and reporting changes to the government about information without any problems. CMS has also included an exception for people who were born before May 13, 2026. Any 855A application received by a Medicare Administrative Contractor before that date can still go through the normal steps, including the site survey. 

For companies that hadn’t filed yet when the freeze started, they won’t be able to bill Medicare until the freeze ends or the application meets other requirements for an exception. CMS has said that the ban can be extended by another six months if it thinks it’s necessary. This means that agencies planning a start in 2026 should not assume that the moratorium will end on a certain date, but should instead plan for an unclear end date. 

The CMS-855A Application: Where Most Delays Begin 

The 855A is the official Medicare enrollment form that all home health agencies need to fill out. It’s also where most of the problems with home health credentials start. The 855A covers an entire organization, not just a doctor’s office. It includes things like who owns the business, how to manage employees, practice locations, and the agency’s clinical and administrative infrastructure. 

Before the Medicare Administrative Contractor gives the 855A its first approval, the state poll can’t even be planned. That one dependency is why many agencies feel stuck early on. The MAC is reviewing it right now; the survey can’t go forward without it. Every step after that, like accreditation, deemed status, and final credentialing, depends on that first approval. 

People often make the expensive mistake of filing the wrong form. If an educational provider files an 855B instead of an 855A, they must start the whole process over. When supporting documents are missing, MAC outreach requests are made, which usually add 30 days or more to the timeline. Also, agencies with complicated ownership structures often have problems with missing ownership declarations, which lead to scrutiny that slows down a file even more. This is because CMS is currently focusing on program integrity in this sector. 

Common Home Health Credentialing Challenges with State Surveys and Accreditation 

Once the 855A passes the first review by the MAC, the survey process brings its own set of common problems with home health credentialing. Agencies can either get a normal state survey from their state survey agency, or they can get approved status through a CMS-recognized accrediting group like ACHC or CHAP. These organizations’ surveys meet both the federal Conditions of Participation and accreditation requirements at the same time. 

Most of the time, deemed status moves faster, but it doesn’t always happen just because it’s private. The service is still judged by the same Conditions of Participation, which cover patient rights, full review, care planning, and quality growth. When agencies haven’t put these standards into practice before the survey, if they treat them as a paper exercise instead of something they do every day, they often find problems that need to be fixed. A follow-up visit is needed before approval is finalized. 

The difference between practicing documents and doing them every day is more important than most first-time applicants think. A policy manual that explains how to do a proper comprehensive assessment won’t help much if the clinical staff who do the assessments in the field don’t follow it. There should be a match between what’s written and what’s happening in patient charts. This is one of the most common reasons why a standard survey ends in a condition-level failure instead of a clean pass. 

OASIS Training, Background Checks, and Staff-Level Credentialing Gaps 

Most of the attention is on organizational credentialing, but staff breaks cause just as many delays. According to the current all-payer submission rules, almost all home health patients must report to OASIS, no matter what kind of insurance they have. The data set was also updated to OASIS-E2 on April 1, 2026. RNs, PTs, OTs, and speech therapists who take this data need to be trained on the most up-to-date form, not an old one from a previous credentialing cycle. 

When agencies don’t get official OASIS training or rely on informal, peer-led teaching, they often don’t realize there’s a gap until a poll shows that ratings aren’t consistent or are wrong. After that, it’s not just a matter of training. It’s a Condition of Participation flaw related to full patient assessment, which surveyors look at very closely. 

Background and license checks finish off the picture at the staff level. Every doctor or nurse who works with a patient’s chart needs to be licensed, have a clean background check, and have records that can be found during a survey and not spread out in personnel files that take days to put together. When you think about how many nurses, therapists, helpers, and social workers are involved, it’s easy to see why staff credentialing needs its own system, not just being added on to other papers. 

CAQH and Insurance Credentialing Add a Second Layer of Work 

While Medicare and state licenses get most of the attention, home health companies that work with Medicare Advantage plans or private payers still need to get CAQH credentialing and standard insurance credentialing. That is not the same as the 855A or state survey process at all. It has its own schedule, set of documents needed, and a 120-day re-attestation period after it goes live. 

When agencies don’t think about CAQH until after Medicare credentialing is complete, they often must deal with two credentialing problems instead of one. A commercial payer relationship that could have started at the same time as Medicare enrollment does not begin until months later. This delays the time when the agency can bill anyone other than traditional Medicare. 

Multi-State Expansion Multiplies Every Requirement 

When an agency works or grows across state lines, it faces a different set of problems that get worse as more states are added. Home health licensing standards vary from state to state. In some states, you need a different home health license in addition to your federal Medicare credentialing. From one state office to the next, survey methods, paperwork guidelines, and even the approval of accrediting bodies can be different. 

As an example, Indiana requires home health agencies to show Medicare provider documentation, along with state survey credentialing and accreditation from a group such as ACHC, CHAP, or the Joint Commission. These are all separate line items in the state’s provider enrollment matrix. Different states set up the same basic requirements in different ways. When a business grows from one state to three, it doesn’t triple its paperwork. When state-specific quirks are taken into account, it’s often four times as much. 

Recredentialing and Revalidation Don’t Pause for Existing Agencies 

It’s important to clear up a common misunderstanding here. The current moratorium stops new Medicare enrolments, but it doesn’t stop agencies that are already certified and billing from continuing to get credentialed. Existing HHAs still need to confirm their Medicare enrollment regularly with CMS, report any changes to their details within the required time frames, and keep their state licenses and approvals up to date. 

Ownership changes add a twist that you should be paying close attention to right now. The moratorium currently stops a change in majority ownership that would normally require re-enrollment within 36 months of a previous enrollment or ownership change. This means that agencies considering a sale, merger, or restructuring need to check to see if that deal would require re-enrollment before going ahead. If this isn’t done right during the deal, the buyer might not get the Medicare payment rights they thought they would get. 

There will also be more inspections of regular revalidation right now, not fewer. CMS has made it clear that the moratorium will be accompanied by more investigations and more data analysis in the home health sector as a whole. These days, a revalidation file with out-of-date information on who owns the business or an address that doesn’t match between PECOS and state licensing records is much more likely to lead to a follow-up request than it would have been 18 months ago. 

What Happens When Credentialing Falls Behind 

There is a real cost to not getting home health credentialed on time. A group that is giving care but can’t bill Medicare because its 855A is still being reviewed by the MAC may never get paid back if the process takes too long and their cash reserves run out. The staff still needs to be paid. People who send you business might not bother if approval takes too long. And right now, when CMS is doing more site visits and keeping a closer eye on the whole sector, a credentialing file that is missing or irregular gets more attention, not less. 

There’s also a cost to your image that keeps going up. When hospitals, physician groups, or discharge planners work with other agencies, they tend to remember which ones had an easy time getting certified and which ones didn’t. In a field where new patients mostly come from referrals, delays in licensing can cost an agency business a lot more than just the lost income. 

Take the example of an agency that opens its doors, hires clinical staff, and starts taking referrals because it thinks that getting Medicare certified is just a formality that will be taken care of in a few weeks. It has been three months, and the 855A is still with the MAC because an ownership statement was missing when it was sent in. The study can’t happen until that approval comes through, so it hasn’t been planned yet. Even though people are being paid and referrals are coming in, Medicare hasn’t been billed for any of this early care yet. By the time the file is cleared and the poll is done, the agency has spent months on costs that would not have been paid for if the application had been complete on the first try. 

How Agencies Can Get Ahead of These Challenges 

Most of these challenges share a common thread: they surface late because nobody was tracking them early. They make sure they have the right CMS-855 form before they file anything, include all information about ownership and managing employees from the start instead of adding it later, and begin CAQH and commercial payer credentialing at the same time as Medicare enrollment instead of waiting. 

They also make OASIS training and staff licensing an ongoing job instead of a one-time task for new employees. From the start, they build multi-state growth plans around each state’s specific needs instead of thinking that what worked in one state will work perfectly in the next. 

Partnering with a team that manages medical credentialing services full-time is often a faster way for agencies that don’t have their own credentialing staff or are still figuring out what qualifies for grandfathering to fill in the gaps than hiring people from scratch. 

Frequently Asked Questions 

Why is home health credentialing challenging?  

It is a single process that includes state licensing, federal Medicare credentialing, private accreditation, and payer-level credentialing. Each track has its own timeline and set of requirements. 

How long does home health credentialing take?  

It varies a lot, but agencies should plan for a few months from the time they file the first 855A to the time they get final Medicare approval, or even longer if the file needs to be fixed. 

What documents are needed?  

Disclosures of ownership and employee management, state licenses, OASIS training records, staff background checks and licenses, and proof of accreditation or surveys. 

How can providers avoid delays?  

Make sure you fill out the right CMS-855 form the first time, keep your records up to date and complete, and begin the CAQH and payer credentialing process early, before Medicare credentialing. 

Should agencies outsource credentialing?  

Many do, especially agencies that don’t have their own credentialing staff, because a specialized partner can keep track of all the dates that meet state, federal, and payment standards at the same time. 

Problems with home health licensing rarely go away on their own time. If you start working on these problems early, they will go more smoothly. This is especially true if you’re dealing with the current Medicare ban, getting ready for a state survey, or making sure all your staff’s credentials are up to date as your team grows. When it comes to home health, medical credentialing services can help agencies keep track of everything that’s going on, from PECOS enrollment to CAQH credentialing, so that billing doesn’t get held up after small gaps.
