- What are acceptable electronic signature notations?
-
All patient medical record entries must be legible, complete, dated, and authenticated in written or electronic form by the person responsible for providing or evaluating the service provided. Electronic signatures should contain date and timestamps and include printed statements (see below) followed by the practitioner's name and preferably a professional designation.
Examples of acceptable electronic signatures are, but not limited to:
- Chart 'Accepted By' with provider's name, designation
- 'Electronically signed by' with provider's name, designation
- 'Verified by' with provider's name, designation
- 'Reviewed by' with provider's name, designation
- 'Released by' with provider's name, designation
- 'Signed by' with provider's name, designation
- 'Signed before import by' with provider's name, designation
- 'Signed: John Smith, M.D.' with provider's name, designation
- 'This is an electronically verified report by John Smith, M.D.'
- 'Authenticated by John Smith, M.D.'
- 'Authorized by: John Smith, M.D.'
- 'Digital Signature: John Smith, M.D.'
- 'Confirmed by' with provider's name, designation
- 'Closed by' with provider's name, designation
- 'Finalized by' with provider's name, designation
- Digitalized signature: Handwritten and scanned into the computer. Be aware that electronic and digital signatures are not the same as 'auto-authentication' or 'auto-signature' systems, some of which do not mandate or permit the provider to review an entry before signing.
Indications that a document has been 'Signed but not read' are not acceptable

- What is CERT?
-
The Centers for Medicare & Medicaid Services (CMS) implemented the Comprehensive Error Rate Testing (CERT) Program to measure improper payments in the Medicare Fee-for-Service (FFS) program. CERT is designed to comply with the Improper Payments Information Act (IPIA) of 2002, as amended by the Improper Payments Elimination and Recovery Improvement Act (IPERIA) of 2012.

- How does the CERT process work?
-
- CERT selects a stratified random sample of claims submitted to Part A/B Medicare Administrative Contractors (MACs) and Durable Medical Equipment MACs (DMACs) during each reporting period.
- CERT requests supporting documentation from the provider or supplier who submitted the claim for payment.
- An independent medical review contractor reviews the documentation to determine if the claim was paid properly under Medicare coverage, coding and billing rules.
- If the documentation doesn't support that the criteria are met, or the provider fails to submit medical records to support the claim billed, the claim is counted as either a total or partial improper payment.
- CERT notifies the MAC who processed the claim if an improper payment is identified.
- The MAC adjusts the claim to recoup (for overpayments) or reimburse (for underpayments) the provider's payment.
- CMS calculates the annual Medicare FFS improper payment rate, which is published in the Health and Human Services (HHS) Agency Financial Report (AFR).
Refer to the CMS CERT webpage for additional information about the CERT Program.

- What information is sent to providers when a claim is selected by CERT?
-
A letter is sent to the provider indicating that a claim has been selected for CERT review. The letter consists of several pages, including instructions for submitting your medical records, the timeframe by which the documentation must be received, and specific information to identify the claim that was selected. One page is a bar coded sheet that lists the specific documentation being requested for the claim and should be used as the fax cover sheet. The letter also contains the FAX number for which documentation should be sent to. Sample letters can be accessed from the CERT C3HUB Provider website C3HUB (cms.gov).

-
- Where does CERT send the request letters?
-
Effective August 14, 2018, the CERT review contractor is sending initial Additional Documentation Requests (ADRs) to the address identified as the correspondence address in the PECOS data file.
Documentation Requests
- All FIRST ADR letters for CERT are sent to the address on file with PECOS for the provider/supplier that billed/submitted the claim.
- All SUBSEQUENT ADR letters can be sent to an alternate address. This can be provided to the CERT Customer Service Representative (CSR) by calling 888-779-7477.
The above processes are based on each individual CID; providers will need to contact the CERT office as mentioned above for each sampled claim.
See the Letters and Contact Information on the C3HUB website.
Chain Address Program
Providers who have at least ten (10) PTAN/OSCAR numbers who would like to elect a single point of contact (POC) can participate in the "chain address" program implemented by CERT. This program is as follows:- Call the CERT office (888-779-7477) or your local MAC CERT Coordinator (6153782.4591) with a list of PTAN/OSCAR numbers and the designated point of contact information.
- To assure you supply the information to CERT within the 45 days, CERT will email/call the point of contact with a list of outstanding CID numbers.
- NOTE: Due to the FIRST letter being sent to the provider address on file, these may be requests the point of contact has not yet received.
- When requested, the CERT CSR will forward a copy of the letters not yet received.
Group Calls
In order to reduce provider burden, when multiple calls are due to the same phone number, the CERT RC groups the calls so that a single contact can be made with the provider (providers) associated with that phone number to discuss all outstanding requests.IMPORTANT NOTE: This change is ONLY in regards to the CERT program.

-
- Do we need the beneficiary's authorization to release the information to the CERT contractor?
-
No, Medicare beneficiaries have already given authorization to release medical information in order to process claims. It is not a HIPAA violation to submit documentation to the CERT contractor.
Reviewed 03/28/2024
-
- Do we need to obtain all the documentation/information from our associated providers?
-
Yes, it is the responsibility of the billing provider to respond to the request for medical records related to the care you provided. This includes all medical records that reside with a third party (e.g. clinics, labs, hospitals, physicians).
Reviewed 03/28/2024
-
- Who are the errors assessed to?
-
The errors are assessed to the Medicare Administrative Contractor (MAC) and the provider who billed the services. When an error is determined, the claim is adjusted by the MAC (e.g. CGS). Providers are notified of claims denied by CERT via their Remittance Advice (RA) or Electronic Remittance Advice (ERA). Provider can appeal any denial received as a result of a CERT review.

-
- What outcomes are expected from the program?
-
The CERT Program supports CMS's primary objectives of ensuring that Medicare contractors are paying claims appropriately, and providers are billing medically necessary services correctly. The error results help identify the areas of greatest vulnerability to the Medicare program and will assist in directing educational activities to reduce the error rates.

- Why would the CERT contractor consider my claim an error?
-
The CERT Assignment of Error Categories document on the CMS website explains when a claim is placed in one of the five major error categories. Tips on how to avoid these errors are listed below.
- No Documentation
- Submit supporting documentation for the service(s) billed within the timeframe indicated on the request. See Avoid CERT No Documentation Errors for additional information.
- Insufficient Documentation
- Review the barcoded cover sheet for a list of documents typically needed to support Medicare payment. The provider that billed the claim is responsible for maintaining and submitting all documentation necessary to support the services billed. In some cases, you may need to obtain records from a different provider (e.g., referring/ordering provider or rendering provider/facility) and/or for dates prior to and/or after the billed date of service.
- Medical Necessity
- Ensure the documentation you submit clearly illustrates compliance with all applicable Medicare statutes and regulations, billing instructions, National Coverage Determination (NCDs), Local Coverage Determinations (LCDs), and provisions in the CMS Internet-Only Manuals (IOMs).
- Incorrect Coding
- Ensure the documentation you submit supports the codes reported on the claim (e.g., procedure and diagnosis codes correspond with AMA/ADA/NUBC coding guidelines; HIPPS codes correspond with patient assessments; patient discharge status codes correspond with the patient's location/care received after discharge/transfer).
- Other
- Ensure the documentation you submit, including a signature, is legible. If necessary, include a signature log or attestation.

- Is there a way to monitor the status of claims that were selected by CERT?
-
- There are two ways to monitor the status;
- One is thru the CERT C3HUB Provider website C3HUB (cms.gov)
- Claim Status Search – This webpage provides current status of a claim under CERT review.
- You may also use the CGS CERT Claim Identifier Tool available to our providers to identify the outcomes of their claim's CERT review. To use this Tool, you must have an established email and password. If you do not already have an email and password for the CERT Claim Identifier Tool, you can apply for one at https://www.cgsmedicare.com/medicare_dynamic/cid_tool/cid_tool/apply.aspx. Once you have access to the tool, enter the Claim Identifier (CID) number assigned to the claim by CERT, and click 'Submit'. You will see the CERT review date, the date of CERT's letter(s) or phone call(s), if the claim was determined to be in error, and the CERT reviewer's comments.
Reviewed 03/28/2024 - There are two ways to monitor the status;
-
- What happens if one of our claims receives an error?
-
- CGS will adjust the claim, and either recoup money (overpayment) or pay additional money (underpayment).
- Letters are sent from the CGS CERT Coordinator with details of your error. These letters are faxed to the fax number on file with the CERT office.
- Sign up for myCGS where you can check on the status of any claim.
- For Part A, Home Health and hospice providers, the adjusted claim can be identified in the Fiscal Intermediary Standard System (FISS) with a TOB ending in an "H" (e.g. 13H, 32H, 81H). Remarks indicating the reason for the CERT error will be entered on FISS Page 04.

- What is a CERT additional documentation request?
-
While conducting medical review of the documentation received, the medical review specialist may identify the need for additional information. A new additional documentation request (Tech Stop) will be issued to obtain the specific item of missing documentation. The response time for this second request is shorter. The CERT Review Contractor follow this schedule:
Subsequent Request Schedule- Day 1: Send letter 1
- Day 1: Telephone contact to follow-up on request and/or offer assistance.
- Day 10: Send letter 2
- Day 10: Telephone contact to follow-up on request and/or offer assistance.

- What causes a CERT error?
-
CERT errors are typically NOT because the services were NOT necessary. Rather, CERT errors usually indicate a failure to submit documentation, or a lack of documentation to support the medical necessity of the services provided. It is important that you respond to any CERT request timely, as no response, or submitting insufficient documentation, will result in a CERT denial and recoupment of Medicare payments.
