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. Insurance Verification & Prior Authorization ▪ Verification of Benefits (VOBs): Meticulous insurance verification to confirm patient deductibles, copays, and coinsurance. ▪ Prior Authorizations: End-to-end authorization tracking to prevent insurance rejections before treatment. ▪ Patient Financials: Upfront insurance verification and copay tracking. 3. Provider Enrollment & Credentialing ▪ CAQH Credentialing: Rapid profile setups, re-attestations, and complete profile maintenance. ▪ Payer Network Enrollment: Insurance credentialing for therapists and doctors across major commercial payers (Aetna, Cigna, BCBS) and government networks (Medicare/Medicaid). ▪ Facility & Provider Onboarding: Complete healthcare credentialing and physician credentialing to get providers in-network quickly. 4. Medical Administration & Virtual Assistant Services ▪ Patient Calling & Relations: Professional patient outreach for billing inquiries, appointment reminders, and follow-ups. ▪ Patient Scheduling: Calendar and appointment scheduling across major EHR platforms to optimize provider time.
