Project details
Unpaid claims, recurring denials, and increasing aging AR can quietly drain your practice’s revenue and disrupt cash flow. My focus is not just submitting claims, but improving the financial performance of your revenue cycle through structured follow-up and measurable tracking.
With 6+ years of hands-on U.S. medical billing experience, I manage eligibility verification, accurate charge entry, clean claim submission, clearinghouse rejection resolution, payment posting (ERA & manual), AR follow-ups, and denial management. I analyze payer-specific trends, identify root causes such as authorization, coding, eligibility, and timely filing issues, and implement corrective action to prevent repeat denials.
I monitor performance using key metrics including Net Collection Rate, Denial Rate, First Pass Resolution Rate, and Days in AR to ensure steady improvement.
Experienced with eCW, Office Ally, Kareo, RXNT, and multi-payer workflows.
My objective is simple: reduce AR, control denials, and strengthen predictable cash flow for your practice.

Medical Billing Expert Needed for Psychology Practice
Zaka did an outstanding job on the task I assigned him. This was a revision-based project to test his capabilities, and he handled it perfectly.
What really impressed me was his proactive approach; he didn't just complete the work, but also provided detailed insights into the practice. These observations were incredibly valuable, as they helped me identify specific deficiencies I hadn't noticed before.
He is clearly skilled, thorough, and brings extra value to the table. I will definitely be hiring him full-time as soon as I complete my transition from my current team.
