John Kariuki

I’m a Detail-oriented Medical Billing Specialist trained in ICD-10-CM, CPT, and HCPCS coding systems. I focus on accurate claim workflows, strong compliance, and cleaner revenue cycle outcomes from eligibility checks through payment posting.

In my recent role with CorroHealth, I followed up on denied and unpaid claims and worked to reduce AR aging over 90 days. I verified patient insurance eligibility and benefits before appointments to help prevent avoidable claim issues.

I submit clean claims to commercial and government payers via electronic clearinghouse, using CMS-1500 and UB-04 claim forms. I manage ICD-10-CM and CPT code assignment for accurate billing, then handle claim outcomes through EOB/ERA processing, denial management, and accounts receivable workflows.

I also post insurance and patient payments, reconcile daily deposits, and maintain HIPAA compliance in all patient data handling. I bring practical training completed in 2024 and proficiency with EHR systems like Epic and Cerner, plus tools like Microsoft Excel to support accurate, detail-driven billing operations.
