What I'm looking for

I’m looking for a US healthcare AR/RCM role where I can prevent denials, recover underpayments, and improve NCR/DAR through payer escalation, RCA-driven process fixes, and clean-claim best practices in a HIPAA-compliant environment.

I’m a Senior AR Caller with 3+ years managing the full back-end RCM lifecycle for US multi-specialty physician group accounts. I focus on denial prevention strategy, payer escalation, and underpayment recovery—driving a Net Collection Rate above 97% and Days in AR under 40 by fixing revenue leakage upstream using root cause analysis and clean claim best practices.

I’ve also scaled results as a team lead, building production tracking systems that lifted Clean Claim Rate by 16% and reduced AR aging over 90 days by 31%. In my current role, I execute high-volume payer follow-ups, run weekly underpayment analysis on posted EOBs, and standardize EBV/charge entry QA protocols to reduce front-end denials while staying fully HIPAA compliant.
