Questions eCW practices ask.
Do we have to leave eCW?
No. You keep eCW, your data and your setup. We work in it as part of your team, and the only new step for your providers is approving the codes the AI drafts.
We pay for eClinicalWorks’ own billing service today. Can we switch to you?
Usually, yes. Check how your eCW contract bundles billing services and what notice it needs. We go through it with you on the call, then run in parallel before the hand-off.
Who on your side sees our patient data?
Only the people working your account, after we both sign a BAA. Each has their own login, so every action is traced to a person. How we handle security.
What will this cost us?
3.5–5.5% of collections · annual agreement · 45-day opt-out. Payers pay you directly, into your bank account. We invoice our fee monthly from posted collections. See pricing.
How long does switching take?
About 30–45 days, with a parallel run before go-live. eCW, your bank account and your payer contracts stay the same. See how switching works.
What if it isn’t working for us?
If it isn’t working in your first 45 days, you can leave, no questions asked. After that it’s an annual agreement, which sets out the notice and how your files come back to you.
