Medical Billing Specialist | Insurance & Eligibility Verification | AR Follow-Up & Denial Management | Prior Authorization | Patient Scheduling | Front Desk If your practice is sitting on unpaid claims, fighting repeated denials, or losing time chasing authorizations I fix exactly that. I am a HIPAA certified Medical Billing Specialist with deep, hands-on experience in the full US revenue cycle. My focus is four core areas where practices lose the most money: Insurance & Eligibility Verification, Prior Authorization, AR Follow-Up, and Denial Management. I don't just submit claims I make sure they get paid. ────────────────────────────── 💡 MY SPECIALTIES ────────────────────────────── ✦ INSURANCE & ELIGIBILITY VERIFICATION Before a patient walks in, I confirm active coverage, deductibles, copays, coinsurance, and out-of-pocket maximums using Availity, UHC portals, BCBS, Medicare, and Medicaid. This prevents claim rejections at the source. ✦ PRIOR AUTHORIZATION & PRE-CERTIFICATION I handle authorization requests, track pending authorizations, follow up with payers, and document approvals so your providers never deliver a service that won't be covered. ✦ AR FOLLOW-UP (Insurance + Patient) I work aging AR buckets (30/60/90/120+ days), identify the root cause of non-payment, and follow up directly with payers via phone and portal. I prioritize high-balance claims to maximize recovery. Successfully recovered high balance claims aged 90+ days, improving cash flow for the practice. ✦ DENIAL MANAGEMENT & APPEALS I analyze denial patterns, correct the root cause whether it's a coding error, missing modifier, or incorrect payer rule and submit clean appeals with supporting documentation. I track every denial through to resolution. ────────────────────────────── 🧰 SYSTEMS & PAYERS I WORK WITH ────────────────────────────── EHR: Athena | eClinicalWorks | AdvancedMD | Office Ally | Kareo Payers: UHC · BCBS · Medicare · Medicaid · Cigna · Humana · Tricare · UMR Portals: Availity · Waystar · Change Healthcare · Noridian ────────────────────────────── ✅ FULL SERVICES OFFERED ────────────────────────────── ✔ Eligibility & Benefits Verification ✔ Prior Authorization & Pre-Certification ✔ Charge Entry & Claim Submission (CMS-1500 / UB-04) ✔ Payment Posting & ERA/EOB Reconciliation ✔ AR Follow-Up Insurance & Patient Balances ✔ Denial Management, Appeals & Resubmissions ✔ DME Billing Support ✔ Patient Scheduling & Front Desk Coordination ────────────────────────────── 🔒 HOW I PROTECT YOUR PRACTICE ────────────────────────────── ✔ HIPAA-certified all data handled in fully compliant workflows ✔ Every claim reviewed against payer-specific rules before submission ✔ Clear communication with turnaround updates you can count on ✔ Available during US business hours for real-time coordination ────────────────────────────── 📩 LET'S TALK ────────────────────────────── Send me a message and tell me: → Which payers are giving you the most denials? → How old is your oldest unpaid AR? → Are authorizations causing delayed care? I'll tell you exactly how I can help and what results to expect.
