Hospital A/R specialist at MedAssist who resolved complex Medicaid claims and researched high-dollar account balances.
United StatesWhat I'm looking for
At MedAssist, a Firstsource company, I worked hospital insurance accounts receivable for multiple clients and was promoted from Account Resolution Specialist I to II. I handled denied, rejected, unpaid, underpaid, and aged accounts, with payer follow-up, appeals, and reconsiderations.
I especially enjoyed difficult cases. I reviewed claim histories, payer responses, EOBs and ERAs, and supporting documentation to identify issues and determine next steps; coworkers also came to me for help with complex California Medicaid claims. I contributed to team research on high-dollar hospital accounts, including balances exceeding $1 million, and documented findings for authorized billing and coding teams.
I hold an active CPC-A certification and have used Epic, Availity, Medicaid and AHCCCS payer portals, and Excel in revenue-cycle work. My more recent roles in skilled nursing and assisted living have kept me connected to healthcare operations and patient care. I'm now looking to return to hospital revenue-cycle work, particularly insurance A/R, denials and appeals, patient accounts, and claims resolution.
