The single largest source of GI denials is the screening-versus-diagnostic distinction — the same procedure pays differently, and patient cost-sharing changes with it.

We manage that logic per payer, coordinate professional billing with ASC facility claims, and handle infusion billing for IBD practices.

Frequently asked questions

Do you bill ASC facility claims?

Yes, alongside professional claims so the two never contradict each other.

Can you handle infusion buy-and-bill?

Yes, including unit calculation, wastage, and authorization tracking.
