AmbuSun is an AI revenue cycle management (RCM) services startup. We work denials and AR follow-up for ambulatory surgery centers and physician practices. Our billers work encounters using software our own engineers build alongside them.
Why this role exists
We're adding ASC and practice clients and need another experienced denials specialist to fight to recover their insurance payments. This is not a queue-grinder seat: you will work denials and aging AR end to end. You'll also work closely with our engineers, testing the internal tools as you work and telling them what to build next.
What you'll do
- Work AR follow-up and prioritize aging accounts by dollars and deadlines, including timely filing limits
- Investigate the root cause of denials, correct and rework claims, and file appeals that stick
- Call payers and navigate portals to resolve follow-ups and appeals
- Apply write-offs and adjustments accurately and keep patient balances clean and explainable
- Give the engineering team direct feedback on the internal billing tools as you work them
What we're looking for
Must have:
- Hands-on denial management and AR follow-up experience
- Billing experience in an ambulatory surgery center and / or private practice with 5+ providers
- Experience with at least one of: eClinicalWorks, athena, NextGen, SIS, HST, Tebra
- Clearinghouse experience: Waystar, or clearinghouse work inside an all-in-one PM like athena
- Authorized to work in the US
Preferred:
- Waystar specifically (strongly preferred)
- Multispecialty background, or depth in ortho / spine / pain, ophthalmology, GI, or OB/GYN
- Big plus: you can also work other parts of the revenue cycle (charge capture, claims submission, eligibility, payment posting)
- Big plus: you're also a coder (CPT, ICD-10, HCPCS, and a working command of modifiers)
- CPC, CPB, CMRS, or CRCS certification (a plus, not required)
- 5+ years of medical billing (strong fit offsets fewer years)
If you don't check every box, apply anyway and tell us what you do have.
Pay and benefits
- $30.00–$35.00 per hour, with the possibility for more for exceptional candidates
- Full-time (W-2): medical, dental, and vision insurance, plus PTO; ideally Monday to Friday (can also swap weekdays and weekend days), with some west coast overlap and otherwise flexible hours
- Part-time: same hourly range, schedule agreed around payer business hours
- Remote anywhere in the US; you'll need a quiet workspace and reliable internet
