Waiting time is covered only when the beneficiary’s attending physician deems it medically necessary. Waiting time is reimbursable after the first 30 minutes. (revised 4/1/16)
If more than four hours of waiting time is required, providers must request individual consideration and provided documentation. Providers should refer to the Billing & Reimbursement for Professionals or the Billing & Reimbursement for Institutional Providers chapters of this manual, as appropriate, for instructions.
