Actions Providers Should Take

Billing Rule

Benefits verification and coding search

Benefits vary by plan. Verify the member's benefits and coverage for the specific drug before providing services. Because new codes may be assigned to these drug(s), search benefits and coverage by HCPCS/CPT code and by drug brand name.

Verify member benefits and eligibility by plan prior to administering or dispensing the drug.
Search by HCPCS or CPT code and by drug brand name (both may be required) due to recent/new code assignments.
Confirm prior authorization, quantity limits, and any plan-specific restrictions before service.
If coverage is unclear, contact Florida Blue provider services or use the payer's provider portal for real-time benefit and authorization information.
