Osama A.
Medical Billing Specialist | Denial & AR Recovery | Credentialing
Medical Billing Specialist for US practices, clinics, and mental health providers: claim submission, coding, payment posting, denial management, and AR follow-up. 98% clean claim rate. AR backlog under 50 days. That's the standard I hold on my current contract, and it's why practices keep me on past the first month. I handle the full revenue cycle, from coding and clean claims to payer follow-up and appeals, and I also support VOBs, prior authorizations, and provider credentialing. I'm US-based, so patient and payer calls happen in your time zone, not on a delay. CORE CAPABILITIES & REVENUE SOLUTIONS 1. Medical Billing & Revenue Cycle Management ▪ Coding & Charge Entry: ICD-10 and CPT coding, charge entry, and documentation review before submission. ▪ Clean Claims Submission: Claim scrubbing, clearinghouse submission, and rejection and error resolution. ▪ Payment Posting: Payments, adjustments, and EOB/ERA reconciliation. ▪ Denial Management & AR Follow-Up: Root-cause research, corrected claims, appeals, and persistent follow-up on aging accounts by payer portal and phone to recover outstanding revenue. 2.
