I work as a Medical Billing and Credentialing Specialist with 5+ years of experience in revenue cycle management (RCM) for U.S. healthcare providers, from solo practices and small clinics to multi-specialty groups. I have recovered over $100,000 in billing backlogs, credentialed providers for a medical group with more than 70 providers, and managed full medical billing and credentialing operations for an ambulance facility. My goal on every project is the same: clean claims, faster payments, and no surprises for the provider. Medical billing and coding services: Full revenue cycle management from charge entry through claim submission on CMS-1500 and UB-04 forms. Medical coding across ICD-10, CPT, and HCPCS, including E/M coding, modifier application, and multi-specialty coding. Insurance eligibility and benefits verification before claims go out, so denials get caught before they happen instead of after. Claim scrubbing and compliance reviews to reduce first-pass denials. AR follow-up and denial management, claim appeals and denial resolution, payment posting and reconciliation, and patient billing, statements, and collections. Provider credentialing and payer enrollment services: Individual and facility credentialing, CAQH profile setup and ongoing maintenance, PECOS enrollment for Medicare and Medicaid billing, commercial payer enrollment and contracting, prior authorization support, multi-state enrollment and re-credentialing, and payer follow-up through full provider onboarding. How I work: I start by reviewing your current billing setup or credentialing needs to find where things are breaking down, whether that's a backlog, a denial pattern, or a stalled payer enrollment. From there I build a workflow around eligibility verification, coding, claim submission, AR tracking, and follow-up, with regular updates so you always know where a claim or credentialing application stands. EHR and billing software I work with: Athenahealth, Kareo, DrChrono, AdvancedMD, eClinicalWorks, Epic, NextGen, PracticeSuite, Office Ally, Availity, Waystar, Zelis, PracticeQ, SimplePractice, TherapyIQ, and TherapyNotes.
