CMS Pub. 100-04, ch. 1, § 70.8.6.1
Monitoring Claims Submission Violations
A. General
Section 1848(g)(4) of the Social Security Act requires physicians and suppliers to submit
claims to Medicare carriers for services furnished on or after September 1, 1990. It also
prohibits physicians and suppliers from imposing a charge for completing and submitting
a claim. Physicians and suppliers who fail to submit a claim or who impose a charge for
completing the claim are subject to sanctions. CMS is responsible for assessing sanctions
and monetary penalties for noncompliance.
Physicians and suppliers are not required to take assignment of Medicare benefits unless
they are enrolled in the Medicare Participating Physician and Supplier Program or, in the
case of physician services, the Medicare beneficiary is also a recipient of State medical
assistance (Medicaid) or the service is otherwise subject to mandatory assignment.
B. Compliance Monitoring
To ensure that providers and suppliers are enrolled in the Medicare program and submit
claims in compliance with the mandatory claims submission requirements found in
§1848(g)(4) of the Social Security Act, contractors shall:
1) Process beneficiary claims submitted to A/B MACs or carriers for services that
are not covered by Medicare (e.g., for hearing aids, cosmetic surgery, personal
comfort services, etc.; see 42 CFR 411.15 for details), in accordance with its
normal processing procedures;
2) Process beneficiary claims submitted to A/B MACs or carriers for services that
are covered by Medicare and the beneficiary has submitted a complete and valid
claim (Form CMS-1490S) and all supporting documentation associated with the
claim, including an itemized bill with the following information:
• Date of service,
• Place of service,
• Description of illness or injury,
• Description of each surgical or medical service or supply furnished,
• Charge for each service,
• The doctor’s or supplier’s name and address,
• The provider or supplier’s National Provider Identifier (NPI)
• The ordering & referring provider’s legal name and address and the National
Provider Identifier (NPI) if known when the itemized bill is from:
A Clinical laboratory for ordered tests
An independent diagnostic imaging center for ordered imaging procedures
A supplier of Durable Medical Equipment, Prosthetics, Orthotics and
Supplies (DMEPOS) for ordered DMEPOS
If the beneficiary furnishes all other information but fails to supply the provider or
supplier’s NPI the contractor shall not return the claim but rather look up the
provider or supplier’s NPI using the NPI registry. If the contractor determines
that the provider or supplier was not a Medicare enrolled provider with a valid
NPI, the contractor shall follow previously established procedures in order to
process and adjudicate the claim.
3) Retain the Form-1490S and supporting documentation and manually return a copy
to the beneficiary if it is for a Medicare-covered service and the claim is
incomplete, does not include all required supporting documentation and/or
contains invalid information. Contractors shall also include an appropriate letter
that specifically communicates all the items listed above which were missing or
invalid. In addition, the CMS-1490S and supporting documentation shall be
maintained for purposes of the timely filing rules in the event that the beneficiary
re-submits the claim.
If the Beneficiary submits a claim on the English or Spanish Form CMS-1490S
(version 01/05) on or after April 1, 2019, manually return the Form CMS-1490S
(version 01/05) claim to the beneficiary, and include a copy of the Form CMS-
1490S (version 01/18), along with a letter instructing the beneficiary to complete
and return the Form CMS-1490S (version 01/18) for processing within the time
period prescribed in §70.5.
If a beneficiary submits a claim on the Form CMS-1500, manually return the
Form CMS-1500 claim to the beneficiary, and include a copy of the Form CMS-
1490S, along with a letter instructing the beneficiary to complete and return the
Form CMS-1490S for processing within the time period prescribed in §70.5,
above. Include in the letter a description of missing, invalid or incomplete items
required for the Form CMS-1490S that were not included with the submitted
Form CMS-1500 or were invalid.
4) Retain Medicare claims records using the following disposition rules.
DISPOSITION:
1. Carriers who Microform Claims
a) Hardcopy Records - Cut off no later than the close of the calendar year (CY) in
which paid. The hardcopy claim must be retained in accordance with the
following:
(1) If a corresponding master microfilm has been made and verified, transfer to a
Federally-approved records storage facility or hold onsite. Destroy after a total
retention of 3 years after the close of the CY in which paid.
(2) If a corresponding master microform record has NOT been made and verified,
transfer to a Federally-approved records storage facility or hold onsite. Destroy
after a total retention of 6 years and 3 months after the close of the CY in which
paid.
b) Microform Records
The master microform record must be retained for a total retention of 6 years and
3 months following the close of the calendar year in which paid.
2. Carriers Who Do Not Microfilm Claims Records
Cut off at the close of the calendar year (CY) in which paid, then transfer to a
Federally-approved records storage facility. Destroy after a total retention of 6
years and 3 months. Earlier cutoff and transfer is authorized. However, the
records must be retained for a total retention of 6 years and 3 months following
the close of the calendar year in which payment is made.
a) Hardcopy Records - The hardcopy must be retained onsite until the microform
has been verified. Cut off at the close of the calendar year in which paid; transfer
hardcopy to a Federally-approved records storage facility only if there is a
corresponding master microfilm record that can be retained for the period
indicated in b. below; otherwise, the hardcopy shall be retained until the 6 years
and 3 months period is reached. Earlier cutoff and transfer is authorized.
However, the hardcopy must be retained for a total retention of 3 years after the
close of the calendar year in which paid.
b) Microform Records - The master microform records must be retained for a
total retention of 6 years and 3 months following the close of the calendar year in
which payment is made.
When returning a beneficiary submitted claim, the contractor shall inform the beneficiary
that the provider or supplier is required by law to submit a claim on behalf of the
beneficiary (for services that would otherwise be payable), and that in order to submit the
claim, the provider or supplier must enroll in the Medicare program. In addition,
contractors shall encourage beneficiaries to always seek non-emergency care from a
provider or supplier that is enrolled in the Medicare program.
If a beneficiary receives services from a provider or supplier that refuses to submit a
claim to the A/B MAC or carrier, on the beneficiary’s behalf, (for services that would
otherwise be payable by Medicare), and/or refuses to enroll in the Medicare program, the
beneficiary should:
(1) Notify the contractor in writing that the provider or supplier refused to submit a
claim to Medicare and/or refused to enroll in Medicare, and
(2) Submit a complete Form CMS-1490S with all supporting documentation.
The contractor shall process and pay the beneficiary’s claim if it is for a service that
would be payable by Medicare were it not for the provider or supplier’s refusal or
inability to submit the claim and/or enroll in Medicare. Claims shall be adjudicated
based on whether the service provided is covered or non-covered/excluded rather than on
the provider’s enrollment status. If for a covered service, the claim shall be processed and the
allowed amount reimbursed to the beneficiary, if appropriate. If for a non-covered/excluded service,
the claim shall be processed and denied with an appropriate MSN message. For
sanctioned/excluded and opt-out physicians/practitioners the following MSN messaging is
recommended:
Sanctioned/Excluded provider or supplier:
A sanctioned or excluded provider or supplier is an individual or business excluded from
participation in the Medicare program for a stated period of time as a result of fraudulent
activity, program abuse, or impermissible conduct as determined by OIG. CMS will pay
the first claim submitted by a beneficiary for the services of a sanctioned/excluded
physician or practitioner and immediately notify the sanctioned/excluded physician or
practitioner of the exclusion. CMS will not pay a claim for sanctioned/excluded
physician or practitioner services more than 15 days after the date on the notice to the
physician or practitioner, or after the effective date of the exclusion, whichever is later.
Under no circumstance may Medicare payment be made to any entity, including
beneficiaries, for services rendered by such providers or suppliers after the first claim is
paid. An example of language that may be considered:
MSN Message 21.27
English
Services provided by a Medicare sanctioned/excluded provider or supplier. No Medicare
payment may be made.
Spanish
Los servicios fueron brindado por un proveedor excluído de Medicare, por lo tanto
Medicare no pagó por los servicios.
Opt-Out physicians and practitioners:
Medicare payment may be made for the claims submitted by a beneficiary for the
services of an opt out physician or practitioner when the physician or practitioner did not
privately contract with the beneficiary for services that were not emergency care services
or urgent care services and that were furnished no later than 15 days after the date of a
notice by the carrier that the physician or practitioner has opted out of Medicare (see 42
C.F.R. 405.435(c)). Therefore, if the beneficiary submits a claim for a service that was
furnished by an opt out physician or practitioner, then the carrier must contact the opt out
physician or practitioner in order to ascertain whether the beneficiary entered into a
private contract with the opt out physician or practitioner. (Note: The carrier should
obtain a copy of the private contract from the opt out physician/practitioner before
denying the beneficiary’s claim if the beneficiary did, in fact, enter into a private contract
with the physician or practitioner.) If the beneficiary did not enter into a private contract
with the physician or practitioner and the beneficiary did not receive notice from the
carrier that the physician opted out of Medicare, then Medicare payment may be made to
the beneficiary for the non-emergency and/or non-urgent care services (assuming that the
services would otherwise be payable). On the other hand, if the beneficiary did enter into
a private contract with the physician or practitioner for the services or received services
from the physician/practitioner 15 days after the date of a notice by the carrier that the
physician or practitioner has opted out of Medicare, then no Medicare payment may be
made. Medicare has instructed opt out physicians and practitioners that private contract
language must include beneficiary instruction precluding the beneficiary from billing
Medicare for these services. An example of language that may be considered:
MSN Message 21.26
English
Claim denied because services were provided by an Opt-Out physician or practitioner.
No Medicare payment may be made.
Spanish
La reclamación fue denegada porque los servicios fueron brindados por un médico ó
proveedor que decidió no participar en Medicare, por lo tanto, Medicare no pagó por los
servicios.
Contractors shall maintain documentation of beneficiary complaints involving violations
of the mandatory claims submission policy and a list of the top 50 violators, by State, of
the mandatory claim submission policy.
Contractors are encouraged to educate providers and suppliers that they must be enrolled
in the Medicare program before they submit claims for services furnished or supplied to
any Medicare beneficiary.
The above policy, including the NPI requirement, is not applicable for foreign beneficiary
claims submitted for covered services. These claims should be processed using
guidelines for foreign claims.
The above policy, including the NPI requirement, is not applicable to beneficiary claims
submitted to DMEMACs for durable medical equipment, prosthetics, orthotics, and
supplies. These claims should be processed by DMEMACs using current procedures.
C. Exception When Physician, Other Practitioner, or Supplier Is Excluded From
Participating in Medicare Program
Section 1848(g)(4) of the Social Security Act requires physicians, other practitioners, or
suppliers to submit claims to Medicare carriers for services furnished after September 1,
1990. This does not apply to physicians, other practitioners, or suppliers who have been
excluded from participating in the Medicare program. Physicians, other practitioners,
and suppliers who have been excluded from the Medicare program are prohibited from
submitting claims or causing claims to be submitted. See the Medicare Program Integrity
Manual for procedures concerning claims submitted by an excluded practitioner, his/her
employer, or a beneficiary for services or items provided by an excluded physician, other
practitioner, or supplier. Carriers must maintain the systems capability to identify claims
submitted by excluded physicians, other practitioners, or suppliers as well as items or
services provided, ordered, prescribed, or referred by an excluded party.
When an excluded physician, other practitioner, or supplier has not submitted a claim on
behalf of the beneficiary and/or the beneficiary has submitted the claim themselves, do not
send a notification letter to the physician, other practitioner, or supplier warning of civil
monetary penalties due to noncompliance with §1848(g)(4)(A) of the Act. Instead, follow
the instructions in the Program Integrity Manual.
