2Member IDYou:"The beneficiary's MBI is [MBI], DOB [date], last name [name]. Can you confirm eligibility is active today?"Rep:(Pulls eligibility — Part A/B active dates, MSP if any, hospice/ESRD flags.)If the MBI is not in their system, ask for the 11-digit MBI from the patient card — Medicare replaced HICNs in 2020.

Any supplier standards or competitive bid area (CBA) restrictions on this HCPCS in this ZIP?"Rep:(Quotes deductible met-to-date, remaining, and any CBA / single payment amount rules.)
-
5Auth / ReferralYou:"Does this HCPCS require a prior authorization under the recent CMS DME prior auth program, or is a written order from the treating practitioner sufficient?
