Ambra (ambra911.com) is your 24/7 EMS billing co-worker, working to recover the underpayments being left on the table. We surface denied claims that are winnable under local policy, write and fax appeal letters automatically, and put voice agents on the phone with payors to challenge inappropriate denials. Agencies using our tools can shorten AR to 40 days and improve their collections by 15-20%. All while freeing up billers to focus on high-impact work, like driving state-level reform to make emergency services sustainable for the long haul.
