According to @mcuban, major insurance carriers and their PBMs deny, underpay, slow pay, and claw back reimbursements while creating administrative mazes for independent physicians and pharmacies, pushing them to sell, shut down, or refer to captive providers, which he says benefits the biggest insurers (source: @mcuban on X, Dec 4, 2025). According to @mcuban, he advocates replacing traditional claims with legally enforceable per-service billable events that must be paid on time with interest for delays, noting carriers and patients already have legal remedies if services are not delivered (source: @mcuban on X, Dec 4, 2025). According to @mcuban, the current system is not an efficient market and needs change, flagging a policy debate on reimbursement timelines and PBM clawbacks that health insurance and PBM equity traders may monitor; he did not mention any crypto or blockchain mechanisms (source: @mcuban on X, Dec 4, 2025).
