Accounts Receivable Specialist

  • Remote (United States hours)
  • United States business hours (Pacific Time)
  • 7+ years experience
  • 1 opening
  • Posted September 29, 2026

You will own the aged accounts receivable for a set of practices: everything over 30 days, by payer and by bucket. You call payers, read remits, write appeals that get paid and bring the 90-plus bucket down month after month. Seven years or more of insurance follow-up is the minimum, because you will work mostly without supervision.

Apply for this role

What you will do

  • Work the A/R aging every day by bucket (31 to 60, 61 to 90, 91 to 120, over 120 days) and by payer, starting with the highest dollar value and the claims closest to an appeal deadline.
  • Check claim status on payer portals and by phone (Availity, UnitedHealthcare, the Medicare contractor portals, state Medicaid portals) and record the reference number, the representative's name and the next step on every account.
  • Read 835 remittances and denial letters, map CARC and RARC codes to a root cause, and route the fix: corrected claim (frequency code 7), reconsideration, formal appeal, or write-off with the reason.
  • Write first- and second-level appeals with the medical record and the LCD, NCD or payer policy reference, and track every appeal to a decision.
  • Spot underpayments against contracted rates and dispute them; identify payer trends (a new edit, a changed policy) and report them to the team lead the same week.
  • Resolve coordination of benefits, timely filing and authorization denials, including retro-authorization requests where the payer allows them.
  • Handle refund and recoupment requests correctly, including the Medicare overpayment rules.
  • Produce a monthly A/R report per practice: days in A/R, percentage over 90 days, collections by payer and the top five denial reasons with what was done about each.

What we need

  • 7+ years of insurance A/R follow-up for professional claims, including at least three years of writing appeals.
  • Strong knowledge of payer appeal processes and deadlines: Medicare redetermination levels, Medicaid timelines, commercial reconsideration windows.
  • Comfortable on the phone with payer representatives for hours at a time: polite, exact and persistent.
  • Able to read a contract fee schedule and an 835 file and tell quickly whether a claim was paid correctly.
  • Experience with practice management systems and clearinghouses (Availity, Waystar, Tebra, eClinicalWorks, athenahealth or similar).
  • Bachelor's degree (any field).
  • Fluent English, written and spoken.
  • Reliable internet, a quiet home office and the ability to work United States business hours (Pacific Time).
  • Pass a background check and sign a confidentiality agreement; HIPAA training is provided and refreshed yearly.

What we offer

  • Salary on the United States pay scale, deposited twice a week, negotiable with experience.
  • Full time, remote, United States business hours (Pacific Time, Monday to Friday).
  • Paid time off and paid United States holidays.
  • Training on the Revelrex EHR and on our billing playbooks during your first two weeks.
