Summary
Aetna's Clinical Trials policy (CPB 0466) clarifies coverage of routine patient care costs for members in approved clinical trials, aligning with CMS and PPACA requirements. The policy covers medically necessary routine care using standard plan rules and utilization management, but explicitly excludes trial-sponsor costs, experimental interventions, travel/lodging/meals, and data-collection-only services. Billing teams must distinguish between covered routine care costs and non-covered trial-specific costs, and verify IRB approval before processing claims.
Action Required
Immediately: Billing team must implement the following clinical trial claim processing protocol: (1) Verify all clinical trial participants have written IRB-approved protocol documentation on file before processing claims—request from provider if unavailable; (2) Apply standard plan coverage policies and utilization management rules to routine care costs (e.g., prior auth, network status, medical necessity); (3) DENY claims for HCPCS codes S9992 (transportation), S9994 (lodging), S9996 (meals), and any protocol-induced costs; (4) Do NOT cover experimental interventions via HCPCS codes S9988, S9990, S9991 unless they qualify as investigational Category B devices or terminal illness exceptions per benefit plan; (5) Update billing system to flag claims with modifiers Q0/Q1 for manual review to confirm trial status and IRB approval; (6) Cover medically necessary complications from clinical trials using standard benefit plan rules; (7) Train front-desk and coding staff to identify clinical trial participants at registration and route claims to specialized processor. Failure to implement may result in inappropriate paid claims for non-covered trial costs and compliance issues with Aetna's CMS-aligned policy.
