This guide covers the main duties of a medical billing virtual assistant, what charge entry and claim submission involve, how clearinghouse rejections get handled, the difference between a rejection and a denial, what payment posting covers, how denials and appeals get worked, what accounts-receivable follow-up looks like, the patient-facing billing duties, and what stays with the practice and the coder.
A medical billing virtual assistant is a remote, healthcare-trained professional who works these tasks inside your own practice-management and billing software. This page lists the work in the order it happens.

What Are the Main Duties of a Medical Billing Virtual Assistant?
The main duties of a medical billing virtual assistant follow the revenue cycle in order, picking up after the visit and the coding, then carrying each claim through to a paid, zero balance. The work is administrative, repeatable, and tied to a clear sequence.
The sections after it walk through each stage.
| Revenue-cycle stage | What the billing VA does |
|---|---|
| Charge entry | Enters charges for completed visits using the codes the coder assigned |
| Claim submission | Builds, scrubs, and submits clean claims to the clearinghouse |
| Clearinghouse rejections | Reads rejection reports, corrects errors, and resubmits |
| Payment posting | Posts payer remittances and patient payments, reconciles to the claim |
| Denials and appeals | Reviews denials, corrects and resubmits, files appeals in payer windows |
| Accounts-receivable follow-up | Works aging buckets, calls payers, chases stalled claims |
| Patient statements | Sends statements, answers patient billing questions, sets up approved plans |
For a plain definition of the role before the task detail, see our guide on what a medical billing virtual assistant is.
How Does a Billing Assistant Handle Charge Entry and Claims?
Charge entry and claim submission involve turning a completed, coded visit into a clean claim, then sending it to the clearinghouse on a set schedule. This is the front of the billing work and the start of the payment clock.
The biller enters charges for completed visits using the codes the coder or provider assigned. The biller doesn't assign those codes, since that's credentialed work that stays with your coder. Once charges are in, the biller builds the claim, scrubs it for obvious errors like a missing modifier or a mismatched detail, and submits the batch to the clearinghouse. Doing this daily, rather than batching once a week, gets clean claims out sooner. A clean first pass also cuts the rework that comes from rejections and denials downstream, so the time spent scrubbing up front pays back later in the cycle. The skills behind clean, fast submission sit in our guide on medical billing virtual assistant skills.
For comparison, the U.S. Bureau of Labor Statistics put the median wage for medical records specialists at $24.59 an hour, or $51,140 a year, in its "Occupational Employment and Wage Statistics" release for May 2025.
How Does a Billing Virtual Assistant Handle Clearinghouse Rejections?
A billing virtual assistant handles clearinghouse rejections by reading the rejection report daily, fixing the error that caused each bounce, and resubmitting the corrected claim quickly. Rejections are different from denials, and the biller treats them as a fast daily queue.
A clearinghouse rejection means the claim didn't pass a front-end edit, so it never reached the payer. The cause is usually mechanical, such as a formatting error, a missing field, or an eligibility mismatch. The biller works the rejection report, fixes each claim, and resubmits before the report grows. The honest payoff is simple. Rejections that get worked the same day don't sit and age into lost revenue.
How Does a Billing Assistant Tell a Rejection From a Denial?
A rejection is a claim the clearinghouse bounced before it reached the payer, while a denial is a claim the payer received, processed, and refused to pay. The two need different work, and a good biller treats them as separate queues.
A rejection usually comes from a mechanical problem, so it gets fixed and resubmitted fast, often the same day. A denial is a decision, so it needs reading and judgment. The biller checks the denial reason, decides whether it's a correctable error or a case for an appeal, and acts on it. Mixing the two queues is how offices lose track of both. Keeping them separate is part of why a dedicated biller recovers revenue that a stretched front desk lets slip. The systems that surface rejections and denials are covered in our guide on medical billing tools and software.
How Does a Billing Assistant Post Payments?
Payment posting covers recording every payer remittance and patient payment against the right claim, then reconciling so the practice's books match what came in. Accurate posting is what makes the rest of the cycle trustworthy.
The biller posts payments from electronic remittances and patient payments, matches each to the correct claim and line, and notes any adjustment, contractual write-off, or patient responsibility as the practice's policy directs. Underpayments and unexpected adjustments get flagged for review. Clean posting matters because it's the foundation for the next stage. You can't work denials or aging accurately if the payments aren't posted right.
How Does a Billing Virtual Assistant Work Denials and Appeals?
A billing virtual assistant works denials and appeals by reading each denial, sorting it by reason, correcting and resubmitting what's fixable, and filing appeals with the right documentation inside the payer's window. This is the duty that recovers revenue most offices quietly write off.
The biller reads the denial and sorts it. A wrong patient detail, a missing modifier, or an eligibility issue gets corrected and resubmitted. A denial that warrants an appeal gets the supporting documentation pulled and the appeal filed before the deadline. Anything that needs a code review or a clinical note gets flagged and routed to your coder or provider, since those calls stay with the credentialed person who owns them. The biller carries the administrative work of the appeal, not the coding judgment behind it. For how this work pays off across the practice, see our page on the benefits of a medical billing virtual assistant.
How Does a Billing Assistant Work Accounts-Receivable Follow-Up?
Accounts-receivable follow-up looks like working the aging report every week, calling payers on stalled claims, and chasing the oldest and largest balances before they go cold. AR follow-up is persistence work, and it's the duty that slips most in a busy office.
The biller pulls the aging report, sorts by bucket and balance, and works the priority items first. Claims stuck in process get a payer call and a status push. Claims that bounced get reworked. Patient balances get followed up through statements and reminders. We keep results qualitative here, since every practice's payer mix and starting point differ, so we won't promise a set timeline. What's reliable is that consistent follow-up is the lever that moves aging, and a dedicated biller brings that consistency.
What Patient-Facing Billing Duties Does the Role Cover?
The role covers sending patient statements on schedule, answering patient billing questions, and setting up payment arrangements the practice has approved. The patient-facing side is administrative, never clinical or care-related.
The biller sends statements on the practice's cycle, answers questions about a balance or an explanation of benefits, and sets up payment plans within the rules the practice sets. Discounts, write-offs, and plan terms stay practice decisions the biller carries out rather than invents. The biller also supports eligibility and verification ahead of visits, so coverage surprises don't turn into denials later. To pick which of these duties to hand over first, see our guide on tasks to delegate to a medical billing virtual assistant.
What Stays With the Practice Rather Than a Billing Assistant?
Code assignment, clinical documentation, and any policy or financial decision stay with the practice, the coder, and the provider, never the billing virtual assistant. The boundary is what keeps the role administrative and safe.
Your certified coder or provider assigns CPT, ICD-10, and HCPCS codes and owns the documentation behind them. The practice owns write-off, refund, discount, and payment-plan policy. The biller works within those rules and flags anything that needs a credentialed call.
