What FDA pathway does my medical AI device need?

Most AI/ML medical devices use 510(k) clearance if a predicate exists (6-18 months), De Novo for novel low-to-moderate risk devices (12-24 months), or PMA for high-risk Class III devices (3-7 years). AI devices that update post-clearance should file a PCCP (Predetermined Change Control Plan) with FDA.

What is the CPT code for FFRCT reimbursement?

CPT 75580 is the permanent Category I code for FFRCT (Fractional Flow Reserve from CT), effective January 2024. It replaced temporary codes 0501T-0504T. Reimbursement is approximately $850-$950 depending on site of service.

How long does NMPA registration take for AI medical devices in China?

NMPA Class III AI medical device registration typically takes 18-24+ months. Chinese clinical data is strongly preferred. Local registration entity is required. Data residency regulations mean patient data generally cannot leave China.

Is FFRCT a good market to enter in 2025?

Likely not — as a direct competitor to HeartFlow. They own ~80% of cloud-based FFRCT, and GE and Siemens are already bundled into existing enterprise contracts. You'd walk into a market where hospitals are already locked in with multi-year deals.

The reimbursement picture has stabilized. CPT 75580 became the permanent Category I code in 2024 (replacing the temporary 0501T–0504T codes), with reimbursement at ~$850–$950 depending on site of service. But the payer coverage is still uneven — some regional plans still lag on adoption. That's a volume ceiling that won't resolve quickly.

The gap worth watching is on-prem FFRCT. Hospitals with strict data residency requirements — VA, government systems, China Tier-1 centers — can't use HeartFlow's cloud pipeline. No dominant player owns that space yet.

If you're building cardiac AI, don't compete on FFRCT as a commodity. Enter as a local-first, data-sovereign alternative. Start by mapping the top 20 hospitals in your target market that have specifically rejected HeartFlow due to data residency. That's your real ICP.
