Altair Health

AI medical billing service that runs a practice's revenue cycle: it checks eligibility and prior authorisation before the visit, validates each claim against the payer's current policies, tracks claims to payment, works and appeals denials, bills patients and posts payments, with in-house billers handling exceptions; the company is also preparing a free EHR for behavioural health with the billing built in.
