With 16+ years of industry-leading expertise, our Florida-based team provides end-to-end Revenue Cycle Management (RCM), precision coding, and dedicated Virtual assistance.

By integrating advanced analytics with personalized support, we ensure your practice meets every regulatory requirement while significantly reducing claim denials and accelerating your total reimbursement cycle.
Not all medical billing is created equal. Each specialty carries its own coding nuances, payer-specific documentation standards, and reimbursement rules. Zenith Assistance has built deep subject-matter expertise across more than 65+ high-complexity medical fields, making us the billing partner of choice for practices where generic solutions simply fall short.
Cardiology billing demands precise modifier application and an advanced understanding of NCCI bundling edits. Our specialists manage high-value cardiac procedures - including EKGs, stress tests, cardiac catheterizations, and interventional cardiology - ensuring every technically complex service is coded accurately with the correct modifiers. We protect your practice from downcoding and bundle disputes while consistently securing the full reimbursement your cardiologists have earned.
DME billing requires mastery of HCPCS Level II coding and strict prior authorization documentation to prevent claim denials. Our specialized DME billing team manages the complete claim lifecycle - from initial equipment orders and Certificates of Medical Necessity (CMN) to payment posting and appeals. We ensure every piece of equipment is coded to reflect true medical necessity, meeting 50-state payer compliance standards throughout the process.
Behavioral health billing is among the most audit-sensitive areas in U.S. healthcare. Our team navigates DSM-5 diagnostic coding, time-based psychotherapy billing rules, and evolving telehealth payer regulations to reduce compliance risk without sacrificing revenue. We understand the documentation requirements that distinguish one level of care from another and ensure your mental health providers are reimbursed fairly and consistently - across in-person and virtual settings alike.
Distinguishing between screening and diagnostic GI procedures is critical to accurate reimbursement - and a common source of costly denials. Our gastroenterology billing team manages procedural bundling rules for colonoscopies, upper endoscopies, and related GI procedures, applying specialty-specific modifiers that unlock the maximum allowable reimbursement. We reduce the risk of payer audits while accelerating payments for your GI practice.
Complex orthopedic procedures - including joint replacements, spinal surgeries, and sports medicine interventions - come with extensive global period rules, post-operative care documentation requirements, and modifier dependencies. Our orthopedic billing specialists navigate all of these complexities with precision, ensuring your surgeons receive appropriate reimbursement for every component of care delivered, from the operating room through the full post-operative period.
High-volume laboratory billing demands speed, accuracy, and an intimate knowledge of molecular testing, toxicology panels, and pathology specimen coding. We manage the technical and professional component split billing for clinical labs and pathology practices, ensuring that every test - from routine bloodwork to complex genetic assays - is coded with the specificity required to withstand payer scrutiny and maintain high-velocity cash flow.

The administrative burden facing today’s healthcare providers is unsustainable. Paperwork, prior authorizations, phone queues, and documentation backlogs steal hours from clinical care every single day. Zenith Assistance’s healthcare virtual assistant services are designed to eliminate that burden entirely – placing HIPAA-trained, EHR-proficient professionals directly into your workflow as a seamless extension of your existing team.
Our medical virtual assistants are not generalists. They are healthcare-specialized professionals who understand clinical terminology, insurance workflows, regulatory compliance, and payer-specific requirements. Each VA operates within your existing EHR environment, understands your practice’s specific workflows, and delivers elite-level administrative support without the overhead costs of a full-time hire.
By offloading these responsibilities to a dedicated healthcare virtual assistant from Zenith Assistance, practices reduce administrative overhead by up to 60%, improve patient experience scores, and free clinical staff to concentrate on delivering the care that drives both revenue and outcomes. All services are delivered under ISO-certified quality standards and strict HIPAA compliance protocols.
Choosing a medical billing company is one of the most important decisions a healthcare provider can make. The wrong partner costs you money, time, compliance standing, and peace of mind. Zenith Assistance was built to be the right choice – a partner that brings measurable results, transparent communication, and a genuine commitment to your practice’s financial health.
