IVIG dosing strategy is changing for the Medicare Part B medical specialty drug program, starting Dec. 7

Blue Cross Blue Shield of Michigan and Blue Care Network require authorization for immune globulin products covered under the medical benefit for Medicare Plus BlueSM PPO and BCN AdvantageSM members.

As part of the authorization process, we're updating our dosing strategy for intravenous and subcutaneous immune globulin therapy to minimize drug waste, reduce unnecessary drug exposure and decrease the risk of adverse events.

Effective Dec. 7, 2020, we'll calculate doses using adjusted body weight for members when:

This applies to all Medicare Plus Blue and BCN Advantage members who start therapy on or after Dec. 7, 2020, when the therapy is administered by a health care professional in a provider office, at the member's home, in an off-campus outpatient hospital or in an ambulatory surgical center (sites of care 11, 12, 19, 22 and 24).

Members who currently receive immune globulin will continue to receive their current dose until their authorizations expire.

Important reminder

For these drugs, submit authorization requests through the NovoLogix® online tool. It offers real-time status checks and immediate approvals for certain medications.

For Medicare Plus Blue and BCN Advantage, if you have access to Provider Secured Services, you already have access to enter authorization requests through NovoLogix.
