Locum Tenens/Reciprocal Billing Arrangements
A. Locum Tenens: For purposes of this rule a “locum tenens” arrangement is defined when the
regular physician retains a substitute physician to take over the practice during an absence. A
regular physician is the physician that is normally scheduled to see a patient. The regular
physician usually pays the substitute physician a fixed amount per diem, with the substitute
physician being an independent contractor rather than an employee.
B. Reimbursement shall be made to the patient’s regular physician for covered services of a
locum tenens physician who is not an employee of the regular physician and whose services
for patients of the regular physician are not restricted to the regular physician’s offices when
all the following criteria are met:
1. The regular physician is unavailable to provide the services,
2. The regular physician pays the locum tenens for the services on a per diem or similar fee-
for-time basis,
3. The Medicaid beneficiary has arranged or sought to receive services from the regular
physician,
4. The substitute physician does not provide the services to the Medicaid beneficiary over a
continuous period of longer than sixty (60) days,
5. The locum tenens physician is an enrolled Mississippi Medicaid provider with a valid
Mississippi Medicaid provider number,
6. The regular physician identifies the services as substitute physician services,
7. The claim is billed with the National Provider Identifier (NPI) of the regular physician,
8. The regular physician keeps on file a record of each service provided by the substitute
physician, and
9. The regular physician ensures that the locum tenens physician is properly licensed to
practice medicine in the state of Mississippi; or, if the regular physician practices in
another state, the state in which the regular physician is licensed to practice.
C. Reciprocal Billing Arrangement: Medicaid defines reciprocal billing arrangement when a
regular physician or group has a substitute physician provide covered services to a Medicaid
beneficiary on an occasional reciprocal basis. A physician can have reciprocal arrangements
with more than one physician. The arrangements need not be in writing.
1. Medicaid covers reciprocal billing arrangements when the regular physician arranges to
be provided by a substitute physician on an occasional reciprocal basis if all the following
criteria are met:
a) The regular physician is unavailable to provide the services,
b) A reciprocal billing arrangement is typically an agreement among physicians that one
will cover the other’s practice when the regular physician is absent. Physicians can
have reciprocal arrangements with more than one physician,
c) The Medicaid beneficiary has arranged or sought services from the regular physician,
d) The substitute physician does not provide the services to a Medicaid beneficiary over
a continuous period of longer than sixty (60) days,
e) The substitute physician is an enrolled Mississippi Medicaid provider with a valid
Mississippi Medicaid provider number,
f) The regular physician identifies the services as substitute physician on the appropriate
claim form,
g) The regular physician keeps on file a record of each service provided by the substitute
physician, associated with the substitute physician’s National Provider Identifier
(NPI), and
h) The regular physician ensures that the substitute physician is properly licensed to
practice medicine in the state of Mississippi; or, if the regular physician practices in
another state, the state in which the regular physician is licensed to practice.
2. Medicaid does not cover reciprocal services for substitution arrangements among
physicians in the same medical group except when a group member provides services on
behalf of another group member who is the designated attending physician for a hospice
patient.
D. Covered Visit Service - Medicaid covers the submission of claims for a medical group under
reciprocal billing arrangements for the covered visit services of a substitute physician who is
not a member of the group. Medicaid defines a continuous period of covered visit services
that begins with the first day on which the substitute physician provides covered visit
services to patients of the regular physician, and it ends with the last day on which the
substitute physician provides these services to these patients before the regular physician
returns to work. This period continues without interruption on days on which no covered
visit services are provided to patients on behalf of the regular physician or are furnished by
some other substitute physician on behalf of the regular physician. A new period of covered
visit services can begin after the regular physician has returned to work.
