Recertification
30.2.1.2 - Recertification
(Rev. 253, Issued: 12- 14-18, Effective: 01-16-19, Implementation: 01- 16-19)
If the patient continues to require active inpatient psychiatric treatment, then a physician
must recertify as of the 12th day of hospitalization (with subsequent recertifications
required at intervals established by the IPF’s Utilization Review committee on a case-by-
case basis, but no less frequently than every 30 days) that the services were and continue
to be required for treatment that could reasonably be expected to improve the patient’s
condition, or for diagnostic study, and that the patient continues to need, on a daily basis,
active treatment furnished directly by, or requiring the supervision of, inpatient
psychiatric facility personnel. In addition, the hospital records should show that services
furnished were intensive treatment services, admission or related services necessary for
diagnostic study, or equivalent services. See Pub.100-01, Medicare General Information,
Eligibility and Entitlement Manual, chapter 4, §10.9, for recertification requirements.
