Rejecting a PECOS entry is very different from being late. If an application is late, it might take 120 days to process instead of 60 days, but it will get accepted in the end. An application that is turned down is completely turned down and must be reapplied for from the beginning. Rejection doesn’t just make things take longer. It ends Medicare involvement for good until the reason for the rejection is fixed and a new application is sent in.
Most rejects are due to things that could have been seen before the application was sent in. They don’t know about the exclusion lists that providers have. Providers claim qualifications they don’t have. Providers lie about their licensing status. Providers don’t tell you about their past of abuse. These aren’t mistakes made by the administration. CMS won’t ignore them because they are real problems.
CMS turns down between 5% and 8% of PECOS applications nationwide. Rejection rates rise to 15 to 20 percent for providers who don’t know what causes most rejections. By knowing what causes rejection, providers can check their work before sending it in, reducing the time it takes to reapply.
This guide lists the main reasons why PECOS rejects applications, explains why CMS requires each one, and gives specific ways to make sure that applications are approved on the first try.
Why PECOS Applications Get Rejected
CMS turns down PECOS applications for two different types of problems. First, administrative rejections occur when important information is missing, incomplete, or inconsistent. Second, a provider is substantively rejected when their background, qualifications, or position make them ineligible to participate in Medicare.
Administrative rejections can be resolved by reapplying. When someone is substantively rejected, they usually need to fix underlying problems before they can reapply.
Missing or Incorrect Information
Incomplete Identity Documentation
PECOS needs all of your papers to match your name exactly. CMS marks the difference as missing proof if a provider’s name is “J.M. Smith” on a driver’s license but “John Michael Smith” on PECOS. By showing proof of name consistency, the source must make it clear that both names refer to the same person.
CMS also needs to make sure that the date of birth on Social Security cards, government IDs, and application papers all match. Discrepancies, even typos that put the year off by one, lead to rejection until they are fixed.
Before you send in your application, make sure your legal name is the same on all your government documents, like your driver’s license, passport, and Social Security card. If you’ve changed your name legally (for example, because you got married, divorced, or changed your name), get proof that your name identity stays the same.
Missing Tax Identification Numbers
Tax Identification Numbers (TINs) must be correct for PECOS to work. Social Security numbers are used by sole proprietorships. EINs are used by businesses. Unique TINs are used for partnerships. Rejection happens when there are mistakes in entering the TIN or when the TIN type does not match the service structure.
Many providers don’t realize that how their business is set up affects the type of TIN they have. If a provider works alone, they should use their Social Security number instead of a business EIN, but they do sometimes enter a business number. Verification fails because the stated structure doesn’t match the TIN.
Prevention: Before you apply, make sure you know what kind of business you have (sole proprietorship, partnership, corporation, or LLC). Find the right TIN for that structure and make sure it fits all the paperwork for registering the business. If you’re not sure, talk to a business lawyer or tax expert.
Inadequate Ownership Disclosure
PECOS needs full and accurate information about everyone who owns 5% or more of the company. A spouse with a financial interest, a business partner with a share of ownership, or a management company with control over operations are all examples of entities that providers often don’t think about when they say “ownership.”
Not giving all the information about control can be done on purpose (like hiding financial interests), but most of the time it’s because people don’t understand what they need to do. Providers don’t know they need to say when family members or business partners own the business, which makes applications incomplete.
CMS compares information about who owns a business with tax returns, company papers, and other supporting documents. If hidden ownership is found during the review, the claim is rejected until more information is provided.
Prevention: Before you apply, make sure you have all the paperwork you need to show that you own a business. This includes the corporate bylaws, partnership agreements, tax returns, and management company agreements. Make a list of everyone who owns at least 5% of the business, even if they don’t work there. If you’re not sure if someone should be on the list, it’s better to be safe than sorry.
NPI and Tax ID Errors
Incorrect or Duplicate NPI Assignment
National Provider Identifier (NPI) numbers are unique numbers that CMS gives to healthcare providers. Providers often ask for more than one NPI without realizing they already have one. Multiple NPIs confuse the system and cause rejection.
Some providers get NPI codes that they don’t understand. They try to get more NPIs because they think the first one didn’t work. During PECOS checking, CMS finds similar NPIs and rejects the entry.
Prevention: Before you apply for PECOS, make sure you already have a valid NPI. Use your name and other details to search the NPI register at npiregistry.cms.hhs.gov. If you already have an NPI, you should use that number on the PECOS form. Do not ask for a new one.
Tax ID Mismatches with Business Structure
PECOS checks to see if the reported business structure matches the type of tax ID. Misalignment happens when a provider says they are a sole proprietorship but lists an EIN. If a partnership lists a Social Security number instead of a partnership tax identification number (TIN), proof fails.
CMS also checks that the TIN matches information from the IRS. CMS will not accept an entry from a provider if the EIN they list on PECOS does not match the IRS’s information for business registration.
Prevention: Before applying, make sure the business structure and TIN are correct. Individual business owners should make sure they are using their Social Security number, not their EIN. Businesses should make sure they use an employer identification number (EIN). Partnerships need to make sure they have a partnership tax identification number. If you’re not sure what TIN is right for your business, talk to your lawyer.
Documentation Mistakes
Unverifiable or Outdated Credentials
CMS checks medical licenses, DEA registrations, and board certifications with the organizations that issued them. If a credential on PECOS doesn’t verify (because it’s expired, isn’t active, or the number doesn’t match), CMS rejects the application until the problem is fixed.
When IDs are out of date, they cause problems. One of the providers lists a board certification that was due for renewal five years ago but was not renewed. CMS calls the specialty board and finds out that the license has expired. They then turn down the application. The source needs to apply for and update the license.
Prevention: Check each password individually before sending it to PECOS. Get the exact license numbers by calling the state medical boards to make sure the licenses are still valid. Call the DEA to check the status of your registration. Get in touch with specific boards to make sure that board qualification is still valid. Renew any credentials that aren’t being used or have expired before you apply.
Falsified or Misrepresented Credentials
When providers lie about their credentials or claim to have credentials they don’t actually have, PECOS rejects the claim. It is dishonest to say you have board certification when you don’t, that you are board-certified when your certification has expired, or that you are licensed by the state when you aren’t actually licensed.
CMS doesn’t ignore false claims about credentials. During regular checks, the agency finds that the application has been falsified and refuses it. They also report the problem to the right authorities. Providers may not only be turned down by PECOS, but they may also be investigated for theft and charged with a crime.
To avoid problems, only list active, up-to-date credentials. Don’t claim to have a board qualification that is no longer valid. Don’t lie about your license status. If you’re not sure if a pass is still valid, you should check with the organization that issued it before filing.
Licensing Issues
Invalid, Suspended, or Revoked Medical Licenses
When companies list medical licenses that have been suspended or cancelled by state boards, PECOS turns down the applications. CMS checks each state license that is listed on the application. If a check of the license shows that it has been suspended or revoked, PECOS does not accept the entry.
Some service companies don’t realize their licenses have been revoked. Someone’s license could have been taken away because of a mistake in the process (like not paying the renewal fee or not finishing their continuing medical education) that the provider meant to fix but forgot about. The problem is found during PECOS verification.
Prevention: Before you apply, check your current standing with each state where you hold a license. Don’t depend on papers you have at home. Get in touch with the state medical boards and make sure that your licenses are valid, up-to-date, and not limited.
Multi-State Licensing Gaps
Providers who work in more than one state need to keep their licenses up to date in each state where they work. If you don’t list a state license or list an expired license from a state where the provider works, you will be rejected.
If PECOS checks, they might find that a service claims to work in five states but only has licenses for four of them. CMS calls the fifth state board and finds that the provider either doesn’t have a license in that state (which is against the law) or has a license that isn’t being used. In either case, rejection happens.
Stopping: Make a list of all the states where you practice or plan to practice. Make sure you have valid licenses for all locations on the list. If you work or plan to work in other states, make sure your license is still valid before you apply.
Enrollment Timeline Issues
Attempting to Enroll Before Credentialing Requirements Are Met
Some companies ask to join PECOS before they have completed the other steps needed to obtain their credentials. For instance, a provider who wants to give banned drugs might apply for PECOS before getting registered with the DEA.
CMS won’t let prescribers join PECOS if they aren’t registered with the DEA. The application is denied, and the person is told to try again after getting DEA registration.
Prevention: Before applying for PECOS, make sure you meet all the standards listed below. Get registered with the DEA first if you’re going to prescribe banned drugs. Make sure that hospital credentialing is complete if you want to get hospital privileges. Make sure all the standards are met before sending in your application.
Outdated Application Information
Providers sometimes wait too long to send in PECOS applications, which means that by the time they get to CMS for review, the information in them is out of date. Someone moved, renewed a license with a new number, or gained or lost a job. The information in the app is out of date and doesn’t reflect reality anymore. CMS rejects forms that have out-of-date information and asks that they be resubmitted with up-to-date information.
Prevention: Fill out the PECOS application and send it in as soon as you have all the necessary paperwork. Don’t wait weeks to send in a completed application because the information in it might have changed.
How to Prevent Rejections
Pre-Application Self-Screening
Before sending in PECOS, do a self-check that includes all of the most common reasons why it will be rejected:
- Are you on any lists of people who are not allowed to participate (OIG Exclusions, GSA Excluded Parties, or state exclusions)? Go to oig.hhs.gov/exclusions and search for yourself. If you find a listing, talk to a lawyer before applying.
- Do you have valid medical licenses in all the states where you work? Call the medical boards in each state to make sure that each license you want to list is still valid.
- If you give banned drugs, is your DEA registration still valid? To make sure the state is current, call the DEA or check CSOS.
- Are all your board certifications up to date and valid? Check the state of your license by contacting the relevant boards.
- Does your tax ID number match the way your business is set up? Make sure that the type of TIN matches the type of business organization.
- Is all information on your application current and accurate? Review every field and verify accuracy before submission.
Proactive Documentation Management
Keep track of all your accomplishments in an organized way before you apply:
Get government identification, like a driver’s license or passport.
Get letters verifying your medical license from all places where you are qualified.
Get a letter from the DEA confirming that you are currently registered.
Ask your malpractice insurance company for a letter proving your coverage.
Get proof of board certification from the relevant specialty boards.
Get proof that you graduated from medical school and that your training was completed.
Ask for proof of business registration that shows your TIN and how your business is set up.
Before sending in your application, put all your documents in one well-organized folder. This preparation helps find problems with the paperwork before CMS looks at it.
Professional Review Before Submission
Before you send in your PECOS application, have credentialing specialists or healthcare lawyers review it. A professional review finds gaps in the paperwork, clarity issues, and possible reasons for rejection that providers miss.
Professional review costs between $500 and $1,500, but it saves you the cost of reapplying and the time it takes to be turned down.
When to Seek Professional Help
Before applying to PECOS, providers with complicated ownership structures, past credentialing issues, or practices in more than one state should get professional credentialing help. Credex Healthcare handles the whole process of enrolling people in PECOS. They do pre-application screening, fix any problems that come up before the applications are sent in, and make sure the applications meet CMS standards for approval.
Professional help is especially helpful for workers who must deal with:
Practices in more than one state (complicated license proof)
Business ownership structures that are hard to understand (complexity of ownership disclosure)
Past rejections or delays of PECOS applications (underlying problems that need to be fixed)
Multi-provider methods (coordinating various apps at the same time)
Hospital ties that need authority authorization (parallel process management)
FAQs
What percentage of PECOS applications get rejected outright versus delayed?
Approximately 5-8% are turned down right away. Twenty to thirty percent more experience delays that require CMS to request more information. 90% or more of the first submissions are approved by providers who focus on prevention (self-screening before filing).
Can rejected PECOS applications be appealed?
Administrative steps can be taken to review a PECOS rejection, but the appeal process takes an extra 60 to 90 days. Most of the time, reapplication (which addresses the real reason for rejection) is faster than an appeal. For substantive rejections (like exclusion status or credential issues), the main problem must be fixed before the applicant can reapply.
How long does PECOS reapplication take after an initial rejection?
When you can reapply depends on why you were turned down the first time. If the problem is routine (lost paperwork or wrong information), the application can be sent again in two to four weeks after the problems are fixed. For serious problems (like losing your license or being put on a list of people who can’t get your license), it could take weeks or months to solve the problem before you can reapply.
What’s the difference between a PECOS rejection and a PECOS delay?
A PECOS delay makes the work take longer, but in the end, approval is reached. When an entry is rejected by PECOS, it is automatically turned down and must be reapplied for or appealed. Delays can be fixed by being patient. Rejections mean you need to address deeper problems.
Should I use professional credentialing services for PECOS enrollment?
Professional services are helpful if your situation is complicated (multiple states, complicated ownership, past problems) or if you don’t have enough internal licensing knowledge. Self-management and careful record-keeping are often enough for simple sole practitioner use. Any doubts should be checked by a professional before submission to avoid expensive rejections.
Final Thoughts
Rejecting a PECOS application is very different from being late. If providers know the causes of rejection, they can avoid it by carefully preparing their work before sending it in. Incomplete information, hidden ownership, invalid credentials, and licensing problems are the most likely reasons for rejection, and they can all be found through pre-application self-screening.
When providers take the time to self-check before sending in their PECOS, they get approval 90% of the time on the first try. 70% to 75% of first-time applicants who submit without proof are approved. For the rest, they must reapply and wait longer for a decision.
Professional licensing help from Credex Healthcare keeps applications from being turned down by experts who prepare and review them before they are sent in. This is especially helpful for providers who aren’t sure about PECOS standards or who must deal with complicated enrollment situations. Putting money into accuracy saves a lot of money in rejection and reapplication delays, which would have cost a lot more.
