Your medical billing department plays a major role in your practice’s cash flow. Your team may submit claims, post payments, and stay busy every day. However, that does not always mean the medical billing department is doing a good job.
To know what is really happening, practice owners and managers need to review billing reports often. These reports show unpaid claims, denials, write-offs, adjustments, and accounts receivable trends. As a result, you can catch problems before they become expensive.
A strong medical billing department should clearly explain what is happening with claims, collections, AR, denials, and write-offs. If the team cannot explain why claims remain unpaid or why staff adjust balances, the practice may lose money without realizing it.
For practices that need extra help with claim follow-up, eligibility checks, authorizations, and back-office work, Ameriton Workforce Solutions offers remote medical administrative support for busy healthcare offices. You can also book a demo with Ameriton Workforce Solutions to see how remote support can fit into your billing workflow.
Medical Billing Department Report #1: AR Aging
First, start with the accounts receivable aging report. This report gives you a clear picture of unpaid money. It also shows whether your billing team works claims quickly or lets them sit too long.
Most AR reports divide balances into aging groups:
- 0–30 days
- 31–60 days
- 61–90 days
- 91–120 days
- Over 120 days
A healthy medical billing department should work older balances often. The team should not let insurance claims sit without follow-up.
What to Check in the AR Report
Practice owners and managers should check:
- How much money sits over 90 days
- How much money sits over 120 days
- Whether the team follows up on old insurance balances
- Whether the team bills patient balances correctly
- Whether the same payers keep appearing in older AR
- Whether the team gives priority to high-dollar claims
If a large amount of insurance AR sits over 90 or 120 days, that is a warning sign. For example, the team may not follow up on claims often enough. Also, staff may miss denials, fail to appeal claims, or leave payer issues unresolved.
Medical Billing Department KPI: AR Over 90 Days
Next, look at the percentage of AR over 90 days. The total AR balance matters, but the age of that balance matters even more.
A lower percentage usually means the billing team follows up quickly and keeps claims moving. On the other hand, a higher percentage may show delayed action, unresolved denials, payer problems, or weak billing habits.
Simple Formula
AR over 90 days ÷ Total AR = AR over 90 days percentage
For example, if a practice has $300,000 in total AR and $90,000 sits over 90 days, then 30% of the AR is over 90 days.
Review this number every month. If it keeps rising, the practice needs to find out why.
Medical Billing Department KPI: Days in AR
Days in AR tells you how long it takes, on average, to collect payment after a visit or procedure.
This number helps show whether the team submits claims, follows up, and collects payment on time.
What to Check
A practice should review:
- Whether days in AR keep rising
- Whether one payer slows down collections
- Whether billing delays hurt cash flow
- Whether the team submits claims quickly after each visit
- Whether the team corrects denials fast enough
If days in AR continue to rise, the medical billing department may need more support, better training, or a stronger follow-up system.
Medical Billing Department Claim Submission Report
A strong billing team submits claims quickly and correctly. Delays in claim submission can delay payment and create cash-flow problems.
Therefore, practice managers should review how long it takes from the date of service to the claim submission date.
What to Check
Check whether:
- Staff send claims daily
- Staff enter charges on time
- Missing information delays claims
- Providers complete charts quickly
- Staff hold claims because of missing authorizations, referrals, or notes
If claims sit for several days or weeks before submission, the practice falls behind before the payer even receives the claim.
Medical Billing Department Denial Report
Next, review the denial report. Denials show where the billing process breaks down. For example, repeated no-authorization denials may point to a front-office issue. However, coding denials may point to charge entry or documentation problems.
According to the Centers for Medicare & Medicaid Services, prior authorization and payer communication continue to be major areas of focus in healthcare administration. You can learn more through the CMS Interoperability and Prior Authorization Final Rule.
Common Denial Reasons
Medical practices should track denials related to:
- Missing or invalid prior authorization
- Missing referral
- Incorrect patient insurance
- Eligibility issues
- Coding errors
- Modifier errors
- Timely filing
- Medical necessity
- Duplicate claims
- Coordination of benefits
- Missing documentation
A good medical billing department does not just work denials. Instead, it studies why denials happen and works to prevent them.
Medical Billing Department Denial Rate
The denial rate shows what percentage of claims payers deny.
Simple Formula
Denied claims ÷ Total claims submitted = Denial rate
A high denial rate can point to problems at the front desk, authorization desk, clinical documentation process, coding process, or billing desk.
For example, if payers deny many claims for no authorization, the issue may start before billing. In that case, the practice may need a better pre-visit checklist. If payers deny claims for coding or modifier errors, the team may need charge entry training.
The goal is not only to appeal denials. Most importantly, the goal is to reduce preventable denials.
Medical Billing Department Write-Off Report
After that, review write-offs. The write-off report shows money removed from account balances. Some write-offs make sense, but others may hide lost revenue.
Contractual adjustments are normal when a payer pays according to the allowed amount. However, not all write-offs are harmless.
Write-Offs to Review Closely
Practice owners should review write-offs for:
- Timely filing
- No authorization
- No referral
- Incorrect billing
- Provider not credentialed
- Lack of documentation
- Patient balance adjustments
- Small balance write-offs
- Courtesy adjustments
- Unexplained adjustments
- Bad debt adjustments
A medical billing department should never write off balances without clear reason codes, approval rules, and notes.
If staff write off large balances because of billing errors, missed deadlines, or lack of follow-up, the practice loses money that it may have collected.
Medical Billing Department Adjustment Report
The adjustment report shows all account changes. These may include contractual adjustments, corrections, administrative adjustments, and write-offs.
In addition, this report helps managers find revenue leaks. Adjustments can make balances disappear, so managers should review them often.
What to Check
Review:
- Who posts adjustments
- Why staff post adjustments
- Whether reason codes are clear
- Whether managers approve large adjustments
- Whether one person posts unusual adjustment amounts
- Whether staff adjust balances instead of appealing them
A clean adjustment report should make sense. If staff use vague reason codes, the practice may not have enough control over adjustments.
If your team is falling behind on AR, denials, referrals, or patient balance follow-up, Ameriton can provide billing support for medical practices without adding another full-time in-office employee.
Medical Billing Department Collection Rate
Collection rate helps measure how much money the practice actually collects.
There are different ways to measure this. However, one of the most useful numbers is the net collection rate.
Net Collection Rate
Net collection rate shows how much of the allowed collectible amount the practice collects.
A strong medical billing department should have a high net collection rate. If the number is low, the practice should review patient balances, appeals, write-offs, payment posting, and claim follow-up.
Medical Billing Department Payment Posting Report
Payment posting must stay accurate and current. If staff post payments incorrectly, the AR report will not show the truth.
What to Check
Practice managers should review whether:
- Staff post payments daily
- Staff post ERAs correctly
- Staff send secondary claims
- Staff move patient responsibility correctly
- Staff post denials with the correct reason codes
- Staff find underpayments
Incorrect payment posting can make the billing team look better or worse than it really is. Also, it can cause patient billing errors, missed secondary claims, and inaccurate AR.
Medical Billing Department Underpayment Report
Medical practices should not assume every payer payment is correct. Payers can underpay claims, bundle services incorrectly, use the wrong fee schedule, or process claims in different ways.
Therefore, an underpayment report helps the practice find payments that need review.
What to Check
Review:
- Payments below contracted allowed amounts
- Repeated underpayments from the same payer
- Incorrect bundling
- Missing drug reimbursement
- Incorrect procedure reimbursement
- Secondary payment issues
- Medicare or commercial payer payment differences
If the billing team does not check underpayments, the practice may leave money uncollected.
Medical Billing Department Patient Balance Report
Patient balances are part of the billing process, but many practices do not review them closely enough.
A patient balance report shows deductibles, copays, coinsurance, and unpaid patient responsibility.
What to Check
Check:
- How much patient AR is unpaid
- How old the patient balances are
- Whether staff send statements often
- Whether staff track payment plans
- Whether staff collect balances at the time of service
- Whether staff write off small balances too often
If the team does not manage patient balances regularly, those balances can become harder to collect.
Medical Billing Department Payer Mix Report
A payer mix report shows where the practice’s revenue comes from.
This report helps the practice understand which payers matter most, which payers pay slowly, and which payers create the most denials.
What to Check
Review:
- Top payers by volume
- Top payers by revenue
- Payers with high denial rates
- Payers with slow payment timelines
- Payers with frequent authorization issues
- Payers with low reimbursement
For example, a practice may find that one payer creates a large amount of work but pays poorly. As a result, that information can help with staffing, contracting, and workflow decisions.
Medical Billing Department Charge Lag Report
Charge lag measures the time between the date of service and the date staff enter charges.
Even if the billing team works hard, delayed charge entry can slow the entire billing process.
What to Check
Review:
- How many days it takes staff to enter charges
- Whether certain providers delay chart completion
- Whether certain procedures need extra review
- Whether missing notes delay billing
- Whether staff enter charges daily
The faster staff enter clean charges, the faster the practice can submit claims and collect payment.
Medical Billing Department Productivity Report
A productivity report helps show how much work each team member completes.
However, managers should not use this report only to criticize staff. Instead, they should use it to find training needs, workflow gaps, and staffing problems.
What to Track
Depending on the role, a practice can monitor:
- Claims submitted
- Payments posted
- Denials worked
- Appeals submitted
- AR accounts touched
- Calls made to payers
- Authorizations completed
- Referrals obtained
- Patient statements processed
- Claims corrected and resubmitted
Productivity should always include quality. A biller who touches many accounts but does not resolve them may not perform well.
Medical Billing Department Red Flags
A practice should review billing performance more closely if it notices these red flags:
- AR over 90 days keeps increasing
- Staff do not submit claims daily
- Staff do not track denials by reason
- Write-offs increase without a clear reason
- Timely filing write-offs occur
- No-authorization denials happen often
- Patient balances age without statements
- Staff do not send secondary claims
- Staff post payments late
- No one reviews underpayments
- Staff cannot explain the AR report
- Staff adjust large balances without approval
- The same denials happen every month
These issues do not always mean the billing team is careless. Sometimes the team is overwhelmed, short-staffed, or missing support from the front office and clinical team.
Questions to Ask Your Medical Billing Department
Practice owners and managers should ask these questions every month:
- What is our total AR?
- What percentage of AR is over 90 days?
- What percentage of AR is over 120 days?
- What is our denial rate?
- What are our top five denial reasons?
- How many claims did staff write off this month?
- Why did staff write off those balances?
- Are we checking underpayments?
- Are secondary claims going out?
- Are staff tracking authorizations and referrals before the visit?
- Are we collecting patient balances regularly?
- Which payers cause the most delays?
- Which claims need manager or provider attention?
A strong billing team should answer these questions clearly and support each answer with reports.
How Ameriton Can Help Your Medical Billing Department
Many billing problems start before the claim goes out. Missing referrals, wrong insurance, expired authorizations, incomplete demographics, and delayed notes can all create billing issues.
Therefore, remote medical office support can help the billing team stay ahead.
Ameriton Workforce Solutions can help practices with:
- Eligibility checks
- Prior authorization tracking
- Referral follow-up
- Claim status checks
- Denial follow-up
- AR support
- Patient balance follow-up
- Medical records requests
- Payment posting support
- Data entry
- Scheduling and recall support
When staff handle these tasks regularly, the billing team can focus on higher-level work instead of chasing missing information all day.
The Bottom Line
A practice should measure the medical billing department by reports, not assumptions.
If managers do not review AR aging, denial rates, write-offs, adjustments, charge lag, payment posting, underpayments, and collections, they may not know how much money the practice delays or loses.
The goal is not to blame the billing team. Instead, the goal is to create better visibility, stronger systems, and clear accountability.
Ameriton Workforce Solutions helps medical practices strengthen office and billing support with trained remote staff. Our team can help with eligibility, authorizations, referrals, AR follow-up, denial support, and other time-consuming back-office tasks.
If your medical billing department needs more support, Ameriton can help you find where remote office support may improve workflow, reduce delays, and protect revenue.
