Certification and Recertification by Physicians for Hospital
10 - Certification and Recertification by Physicians for Hospital
Services – General
(Rev. 1, 09-11-02)
Payments may be made for covered hospital services only if a physician certifies and
recertifies to the medical necessity for the services at designated intervals of the hospital
inpatient stay. Appropriate supporting material may be required. The physician
certification or recertification statement must be based on a current evaluation of the
patient's condition.
For patients admitted to a general hospital, regardless of whether the patients are under
PPS, a physician certification is not required at the time of admission for patient services.
For services continued over a period of time or for a day outlier case (i.e., an
appropriately admitted case results in an extraordinarily long stay) or for a PPS cost
outlier case (i.e., an appropriately admitted case results in the expenditure of
extraordinary resources), a physician must certify or recertify the continued need for the
services at specified intervals. (See § 80 for timing of physician certification and
recertification.) Psychiatric and tuberculosis hospitals (which are excluded from PPS) are
required to obtain a physician certification on admission.
Hospitals do not transmit physician certification and recertification statements to the A/B
MAC (A) or to CMS. The hospital must itself certify on the appropriate billing form that
the required physician certification and recertification statements have been obtained and
are on file. The physician certification and recertification statements are retained in the
hospital's file where they are available for verification if needed.
A hospital must also have available in its files a written description of the procedure it
adopts on the timing of certifications and recertifications, i.e., the intervals at which the
necessary certification statements are required and whether review of long stay cases by
the utilization review committee may serve as an alternative to recertification by a
physician in the case of the second or subsequent recertification.
