How many attempts are made to complete a site visit?

Generally, two attempts are made to complete a site visit. However, if on the first attempt, the inspector finds the facility is still under construction, finds other obvious indications the facility is not a true operating location, or finds that there is no visible sign or office hours posted, the site inspector will not make a second attempt and the NSC will be notified the site visit could not be completed.

The hours of operation indicate when a supplier is open and available. During these hours, a beneficiary, CMS or its agents should be able to visit the facility. If a supplier goes to lunch from 1 p.m. to 2 p.m., then this needs to be posted along with the hours of operation. If your posted hours state you are open from 9 a.m. to 5 p.m., then the supplier should be available from 9 a.m. to 5 p.m.

Note: Suppliers should not include times of delivery or maintenance to Medicare beneficiaries in their hours of operation.

If a site visit is refused or unable to be conducted, the supplier is subject to the denial/revocation of Medicare billing privileges.
