What I'm looking for

I seek a role in revenue cycle or billing where I can resolve denials, improve claim accuracy, and collaborate with providers and payers in a compliance-focused, team-oriented setting.

I am a dedicated medical billing and revenue cycle specialist with years of experience managing claims, appeals, authorizations, and payer communications across remote, hybrid, and onsite environments.

I have a proven record of submitting accurate CPT and ICD-10 coding, reconciling patient encounters, and meeting productivity and accuracy benchmarks while maintaining compliance with payer and value-based care requirements.

My background includes crafting well-supported medical appeals, researching payer requirements, procuring medical records, and resolving denials to secure reimbursements. I routinely collaborate with providers, patients, and payers to close outstanding balances and prevent future denials.

I bring attention to detail, strong communication skills, and a commitment to process improvement, having worked in roles from customer support and escalation handling to subject matter expert and billing specialist.
