A-Z was built by the operators of Vally Medical Group, a multi-location practice in Hawaii. We couldn't find a billing company that worked as hard as we did. So we built one. Our AI scans your entire claims history before a human ever touches your account.
We'll send your revenue analysis within 48 hours.
We connect to your EMR through Waystar and run a proprietary intelligence layer across your entire claims history. Every denial pattern, every payer-specific trigger, every dollar sitting in your backlog ranked by recovery probability. This is why we recover revenue other billing companies write off as dead.
Our AI clusters your denial history by payer, code, and reason. It surfaces patterns your team can't see, like Aetna denying 99214s at 3x the rate of United, or a credentialing gap causing silent CO-185 rejections across an entire provider.
Avg 47 patterns found per practiceMost practices have 6-18 months of denied claims sitting in their system that nobody has worked. Our engine scores every claim by dollar value, filing deadline, and appeal success probability, then attacks the highest-ROI recoveries first. Claims your old biller gave up on.
$127K avg recovered per practiceEvery future claim passes through our AI before it leaves your system. It checks payer-specific modifier rules, bundling logic, NPI accuracy, and documentation requirements. Errors that would become denials in 30 days get caught before they cost you money.
96% clean claim rate



















Most billing companies learned the business from textbooks and compliance manuals. We learned it the hard way—running Vally Medical Group, a multi-location practice in Hawaii, where every denied claim meant real consequences for real patients.
Our founder didn't start in medical billing. He started in the trenches of practice operations, dealing with the same impossible insurance companies, the same predatory contracts, and the same cash flow crises you face every month. When a major insurer changed their submission requirements overnight, we were the practice scrambling to adapt.
That's why when you call us about a denial, you're not talking to a call center script-reader in Manila. You're talking to someone who has personally fought—and won—the same battle with the same payer that just denied your claim.
Real results from practices that chose to stop losing revenue
"We were with [Previous Company] for 6 years. They were fine—until A-Z showed us we were 'fine' with leaving $94,000 on the table every year. The transition took 45 days. We hit 96% clean claim rate in 60 days. I can't believe we waited this long."
"I was terrified to switch billing companies mid-year. A-Z ran parallel with our existing biller for 30 days—no disruption, just proof. When I saw they recovered $12,000 in claims our old company had written off as 'unappealable,' the decision made itself."
"The difference is night and day. With our old company, I'd submit a ticket and wait 3 days for a generic response. With A-Z, I text my account manager and get a real answer in 20 minutes. They actually KNOW my practice."
