Key Differentiators

12 minutes vs days

Infinx routes your PA work to a staffed back office. Even efficient back offices take 1–5 days per case. RxCheckUp drafts a payer-specific LMN with evidence in about 2 minutes — your team keeps the patient moving.

2Flat subscription beats per-case fees

Outsourced PA services charge per case, which gets expensive fast at volume. RxCheckUp’s flat subscription covers unlimited LMNs for one predictable price.

3Always-on, in your control

A subscription tool is available 24/7 from any device. Your staff drafts and signs the LMN themselves — no handoff to an external team, no waiting on someone else’s queue.
