It is time to switch your medical billing provider when your denial rate stays above 8 to 10%, days in accounts receivable climb past 40, your clean claim rate is below 95%, you cannot get clear monthly reports, denials and underpayments are written off instead of appealed, your account team is hard to reach or the company cannot show HIPAA and security safeguards. One of these is a warning. Two or three together usually mean your billing company is costing you more than it charges.
This guide explains each of the 7 signs, the 2026 benchmarks to measure your current billing company against, and how to switch medical billing providers without losing cash flow. Benchmarks come from MGMA and HFMA targets and Experian Health’s 2026 State of Claims survey.
Signs to Switch Your Medical Billing Provider at a Glance
- Sign 1: denials keep rising and no one explains why.
- Sign 2: days in AR are over 40 and old claims pile up past 90 days.
- Sign 3: clean claim rate is under 95%, so claims bounce back as rejections.
- Sign 4: reports are late, vague or missing, and you cannot see your own data.
- Sign 5: net collections are under 95% because denials and underpayments get written off.
- Sign 6: slow answers, constant staff changes and missed deadlines.
- Sign 7: weak compliance and data security, with no signed BAA or audit trail.

2026 Medical Billing Benchmarks to Measure Your Provider Against
Before deciding to switch medical billing providers, compare your numbers with these industry targets. Ask your current company for the last 6 to 12 months of each metric. If they cannot produce them, that is already a red flag.
Medical billing benchmarks 2026
Six numbers every practice should see each month
Clean claim rate. Claims accepted on the first submission.
Initial denial rate. Best performers stay near 3%.
Days in AR. High performers are under 30.
AR over 90 days. Share of total receivables.
Net collection rate. Under 90% signals a problem.
Medicare filing limit. Missed deadlines mean lost revenue.
| Metric | Healthy target | Time to worry |
|---|---|---|
| Clean claim rate | 95% or higher | Below 90% |
| Initial denial rate | 8% or lower (best in class 3%) | Above 10% or rising each quarter |
| Days in accounts receivable | Under 40 days (high performers under 30) | Over 50 days |
| AR over 90 days | Under 10% of total AR | Over 15% |
| Net collection rate | About 96% | Below 90% |
| Denials appealed | Every recoverable denial worked | Denials written off without review |
Targets are summarized from MGMA and HFMA benchmarks reported by ADSC. Specialty, payer mix and state can move these numbers, so compare against practices like yours and look at the trend, not just one month.
Top 7 Signs It’s Time to Switch Your Billing Provider
1. Your denial rate keeps climbing and nobody explains why
Denials are rising across the industry. In Experian Health’s 2026 State of Claims survey, 75% of providers said denials are increasing and 40% reported denial rates above 10%. That makes a strong billing partner more important, not less. The warning sign is not one bad month; it is a denial rate above 8 to 10% that keeps rising while your billing company sends no root-cause analysis.
A good partner tells you which payers and codes drive denials, fixes the cause upstream (eligibility, prior authorization, coding, documentation) and shows the trend coming down. See our guide to medical billing denial management for what that process should look like.
2. Days in AR are high and old claims keep aging
If your days in accounts receivable are over 40, or more than 10% of your AR is older than 90 days, money is sitting with payers instead of in your bank. Aging AR usually means claims are not followed up, rejections are not reworked and denials are not appealed before deadlines. Every week a claim sits, the chance of collecting it drops.
Tip: Ask for an aging report by payer in 0 to 30, 31 to 60, 61 to 90, 91 to 120 and over 120 day buckets. If the over 90 buckets are growing month after month, your billing company is falling behind.
3. Your clean claim rate is below 95%
A clean claim is accepted the first time. A low clean claim rate means front-end mistakes, such as wrong patient or insurance details, missing modifiers, invalid codes or claim scrubber edits that nobody updates. Each rejection delays payment and creates rework. A billing company that has not invested in claim scrubbing and eligibility checks will keep repeating the same errors. These are the common medical billing errors that should be caught before submission.
4. You cannot see your own numbers
You should receive a clear monthly report with charges, payments, adjustments, denial rate, days in AR, aging and collections by payer and provider. If reports are late, change format every month, only show totals or require you to ask repeatedly, you cannot manage your practice. Warning signs include:
- No direct read-only access to your practice management or billing system.
- Reports that show charges and payments but never denials or write-offs.
- Different numbers from your bank deposits with no explanation.
- Fees that rise or new charges you never agreed to.
You own your data. Our medical billing reporting services page explains what transparent reporting should include.
5. Net collections are low because claims get written off
A net collection rate under 95% means you are not collecting money you are owed under your contracts. The most common cause is quiet write-offs: denials marked uncollectible, underpayments never compared with the contract, and timely filing deadlines missed. Medicare’s general limit is 12 months from the date of service, according to CMS guidance, and many commercial plans allow far less.
Important: For out-of-network emergency and specialty claims, underpaid amounts can often be disputed through federal or Texas IDR. A billing company that never mentions IDR may be leaving significant revenue behind. Check eligibility with our free IDR Claim Checker.
6. Communication is slow and the team keeps changing
You should know who handles your account and get answers within one business day. Frequent turnover, offshore teams with no practice-specific training, unanswered emails and missed payer enrollment or credentialing deadlines all lead to lost revenue. If you only hear from your billing company when an invoice is due, the relationship is not working.
7. Compliance and data security are weak
Your billing company handles protected health information, so it must sign a HIPAA business associate agreement, limit access, keep audit trails and show how it protects your data. The 2024 Change Healthcare cyberattack, which affected about 193 million people, showed how a single vendor problem can stop claims for weeks. Also watch for coding red flags: outdated or invalid codes, routine upcoding or downcoding and no regular coding audits. These create audit and repayment risk for you, not just for the vendor.
Quick Scorecard: Should You Switch Medical Billing Providers?
Answer yes or no to each statement about your current billing company:
- Our denial rate is above 8% or has risen for two quarters in a row.
- Days in AR are over 40, or more than 10% of AR is older than 90 days.
- Our clean claim rate is below 95%, or we do not know it.
- We do not get a clear monthly KPI report without asking.
- Denials or underpayments are written off without appeal.
- We wait more than a day for answers, or our contact keeps changing.
- We have no signed BAA or have never seen a coding or compliance audit.
Key takeaway: 0 to 1 yes answers: talk to your provider and set targets. 2 to 3: ask for a written improvement plan with a 90-day deadline. 4 or more: start planning to switch your medical billing provider now.
Fix or Switch? When to Give Your Billing Company a Chance
Not every problem means you need a new company. Some issues come from inside the practice, such as missing documentation, late charge entry or front-desk eligibility errors. Before you switch:
- Share the benchmark table above and ask for a written plan with specific targets and dates.
- Separate practice-side causes (documentation, registration) from billing-side causes (follow-up, appeals, coding).
- Get an independent medical billing audit of a sample of claims, denials and write-offs.
- Review the contract for performance guarantees, termination notice and data ownership.
If the targets are missed after 90 days, or the company will not commit to them in writing, it is time to switch.
How to Switch Medical Billing Providers Without Losing Revenue
Most cash flow problems during a change come from poor handover, not from the new company. Follow these steps:
- Read your current contract. Note the termination notice period (often 30 to 90 days), fees for ending early and who will work old claims after the end date.
- Secure your data. Request a full export of patient, claim, payment and AR data, plus open denial and appeal files, in a usable format before you give notice.
- Pick the new company and sign a BAA before any data is shared.
- Update payer connections. Move clearinghouse, ERA and EFT enrollments and confirm credentialing and payer enrollment are current for every provider.
- Agree on runout. Decide in writing whether the old company works existing AR for 60 to 90 days or the new company takes over all open claims on day one.
- Run both in parallel for the first month and compare submissions, rejections and payments daily.
- Track the first 90 days against the benchmarks: clean claim rate, denials, days in AR and collections.
If cost is part of the decision, compare the full picture, not just the percentage. Our guide to what it costs to outsource medical billing and our medical billing pricing page explain what is usually included.

Switching Medical Billing Providers: FAQs
When should I switch my medical billing company?
Switch when two or more warning signs persist: denial rate above 8 to 10%, days in AR over 40, clean claim rate below 95%, unclear reporting, written-off denials, poor communication or weak HIPAA safeguards. If a written improvement plan does not fix them within about 90 days, it is time to change.
What is a good denial rate for a medical practice?
MGMA benchmarks put a healthy initial denial rate at 8% or lower, with best performers near 3%. A rate above 10%, or one that rises every quarter, is a red flag.
What are good days in AR for medical billing?
Under 40 days is a common target for physician groups, and high performers stay under 30 days. Less than 10% of AR should be older than 90 days.
How long does it take to switch medical billing providers?
Most switches take 30 to 90 days, depending on the notice period in your contract, data export, clearinghouse and ERA/EFT enrollment changes and how old AR is handled.
Will switching billing companies disrupt my cash flow?
It can if handover is rushed. Export your data first, agree in writing who works old AR, update ERA and EFT enrollments early and run both companies in parallel for the first month to avoid gaps.
Who owns my billing data when I switch?
Your practice owns its patient and billing data. Your contract should state that the billing company must return all data in a usable format when the agreement ends.
What should be in a medical billing company contract?
Fees and what they include, performance reporting, termination notice and fees, data ownership and return, handling of old AR after termination and a signed HIPAA business associate agreement.
