6.2.5 - Medical Necessity of Services Provided
(Rev. 603, Issued: 07-21-15, Effective: 08-11-15, Implementation: 08-11-15)
In addition to certification and recertification requirement documentation, contractors
shall also review the medical record documentation to determine whether services
provided were medically necessary. Again, home health generated information must be
reviewed, signed off by the certifying physician and incorporated into the certifying
physician medical record for the patient or the acute/post-acute care facility’s medical
record for the patient (if the patient was directly admitted to home health) if used to
support certification/recertification.
