a16z Newsletter · rss · 2026-10-13

A Prosper AI study (via a16z) quantifies $125,000/year per physician in revenue opportunities for US specialty practices, combining data from $3B+ in managed care and a CallIQ study of 2,000 practices in 29 states. Four AI levers: AI call answering (1-in-6 daytime calls go unanswered; 81% after hours) worth $44,800; proactive patient recall worth $37,400; pre-visit insurance verification to prevent denials (10% of first claims denied) worth $28,500; and AI outbound calls to recover unpaid patient responsibility worth $14,100. Case study: a dermatology practice saw appointments rise 17% and peak wait times drop from 7 minutes to zero. Pressure mounts as 84% of groups report rising costs and a temporary 2.5% Medicare payment boost expires end-2026.
