Signing the contract is not the finish line. It is the start of a 90-day test — and most practices never actually run it. The relationship drifts on impression: the contact seems responsive, collections seem steadier. Impressions are not evidence. The first quarter is when you have the most leverage and the clearest comparison point, because your pre-hire baseline is still fresh. This guide covers which medical billing performance metrics to track, what good reporting looks like, and which red flags matter at day 30, 60, and 90.
If you are still comparing companies, start with our guide on how to choose a medical billing company. Everything below assumes you have already chosen.
Step zero: freeze your baseline before the first claim moves
A scorecard is useless without a “before” picture. In the first week, record your last three months under the previous arrangement: denial rate, first-pass or clean claim rate, days in A/R, net collection rate, the share of A/R over 90 days, and total collections by payer. Pull the figures yourself from your practice management system where you can, using the same definitions you will use all quarter. Our overview of medical billing KPIs explains each measure.
Also record how much A/R the new company inherited, by aging bucket — inherited balances and new work must be judged separately — plus your transition facts: enrollment or EDI changes, when the first claims went out, and who owns follow-up on claims the previous biller submitted. By day 60, no one remembers these the same way.
The six metrics that carry the scorecard
You do not need thirty metrics. You need six, calculated the same way every month, split by payer for your top payers.
First-pass / clean claim rate. The share of claims accepted and paid, or at least accepted without error, on first submission. It is your earliest signal: it moves within weeks, long before cash does. One billing vendor, MedHeave, publishes targets of above 95% for clean claim rate in its own guidance — treat that as a vendor-stated target to discuss, not an independently verified industry standard, and judge your company mainly on direction: rising toward its own stated target, from your baseline.
Denial rate. Denied claims divided by submitted claims. Context matters here: in Experian Health’s State of Claims 2026 survey of 204 healthcare professionals in finance, billing, registration, reimbursement, claims and collections roles, 40% of providers said 10% or more of their claims are denied, and 89% said reducing denials is a priority for 2026. Denials are common — which is exactly why your company’s denial trend and handling, not a single month’s rate, is the test. MedHeave’s vendor guidance sets a target below 5%; again, use it as a conversation anchor, and require the rate to be reported by reason and by payer, not as one blended number.
Days in A/R. Total receivables divided by average daily charges. It answers “how long does money sit unpaid?” MedHeave’s vendor target is below 35 days. Whatever figure you adopt, agree it in writing and watch the trend: days in A/R should be flat-to-falling by day 90 once transition effects are separated out.
Net collection rate. Payments divided by charges minus contractual adjustments — what you collected of what was actually collectible. This is the metric that resists gaming, because it is measured against allowed amounts, not gross charges. MedHeave’s vendor target is above 95%. A company can show pleasant activity reports while this rate quietly falls; if you track only one number monthly, track this one.
A/R over 90 days. The share of receivables older than 90 days, shown separately for inherited and new balances. One vendor, Clarity Health RCM, states in its own guidance that if more than 20–25% of A/R is past 90 days, something is wrong — a vendor benchmark, not a studied standard, but a useful alarm line to agree on. The direction matters most: the inherited 90+ bucket should shrink every month, with named actions behind the shrinkage.
Reporting and follow-up activity. Counts are not performance, but absence is a finding: claims submitted, denials worked, appeals filed, and payer calls made, each with dates.
What good reporting looks like — and what it hides
Reporting transparency is the brief’s first evaluation criterion for a reason: it is how every other criterion becomes visible. A good monthly package arrives on a fixed date, uses the same layout each time, shows the six metrics above against baseline and prior month, splits key figures by payer, ages A/R in standard buckets, and lists denials by reason with the action taken. It also reports bad news in the same size type as good news.
Our walkthrough of how to read your monthly medical billing report covers the line-by-line reading. In the first 90 days, add three tests: trace five payments and five denials from the report to remittances; confirm each metric’s formula does not change between months; and check whether your team can see claim-level detail without filing a request. MGMA’s January 6, 2026 Stat poll of 288 medical group leaders found denials and appeals named the biggest revenue-cycle leak by 48% of respondents — a practice cannot manage its largest leak through summary slides alone. Watch for flattering reporting: gross figures without contractual adjustments, denial rates that exclude rejections, and A/R totals without aging.
Reading the other criteria through the scorecard
Denial management. By day 60 you should be able to see, for your top denial reasons: volume, owner, action, and whether the same reason recurs next month. A company that only appeals — without feeding causes back into eligibility, authorization, or coding — will show a busy appeals log and an unchanged denial rate.
Aging A/R and payer experience. Ask for follow-up by payer, not in aggregate. Payer experience shows up as specificity: which payer is slow, on which claim types, what was said on the last call, and what escalation comes next. “Working the A/R” with no payer-level notes is a red flag at any day count. Inherited A/R deserves its own line: balances worked, balances paid, balances identified as uncollectible — with reasons.
Communication. Agree the cadence up front: a named contact, a scheduled monthly review, and a response-time expectation for urgent claim issues. Then score it like a metric. Missed reviews and unanswered questions in month one rarely improve unprompted in month three.
Security. In the first 30 days, confirm the basics: the business associate agreement is signed, system access is role-based and limited to your account’s team, and you know how your data is returned if the relationship ends.
Pricing clarity. Reconcile the first two invoices against the contract line by line. Fastora, for comparison, prices on a percentage of collections or a flat monthly fee — whichever model your company uses, the test is the same: every charge should map to a contract term, and anything extra — credentialing, statements, special reports — should have been named before it was billed, not discovered after.
Red flags by day 30, 60, and 90
By day 30 — setup flags. No baseline agreed; first report late, redefined, or missing payer detail; inherited A/R untouched with no work plan; you cannot name who works your account. Transition genuinely takes time — vendor guidance in the facts behind this article puts a well-managed transition at roughly 30 to 90 days — but organization should be visible immediately even when results are not.
By day 60 — pattern flags. Denial reasons repeat with no prevention action; days in A/R rises and is explained only with payer blame; the 90+ bucket grows for new claims, not just inherited ones; review meetings slip.
By day 90 — judgment flags. Net collection rate is flat or down against baseline with no credible, dated improvement plan; reporting still cannot be reconciled to remittances; pricing surprises have appeared. At day 90, hold the formal review: scorecard on the table, variances explained, and the next quarter’s targets agreed in writing — or a contract conversation started while your leverage remains.

Copy this table and fill it in at days 30, 60, and 90. Score each row Met / Watch / Missed against the target you agreed at signing.
| Area | What to record | Your target |
|---|---|---|
| Clean claim / first-pass rate | This month vs baseline | |
| Denial rate | Overall, plus top 3 reasons by payer | |
| Denial handling | Denials worked, appealed, prevented next month | |
| Days in A/R | Overall and for top 3 payers | |
| Net collection rate | Vs baseline, same formula | |
| A/R over 90 days | Inherited bucket and new bucket, separately | |
| Reporting | On time? Reconciles to remittances? Payer detail present? | |
| Communication | Review held? Questions answered within agreed time? | |
| Security & access | BAA signed, access confirmed, data-return terms clear? | |
| Pricing | Invoice matches contract, no unnamed extras? |
A scorecard with two or three Watch rows and a credible plan is a normal first quarter. A scorecard the company will not fill in with you is itself the answer.
Frequently asked questions
What KPIs should my billing company report every month?
At minimum: clean claim or first-pass rate, denial rate by reason and payer, days in A/R, net collection rate, A/R aging with the over-90 share, and the follow-up activity behind those numbers. Same definitions, same layout, same delivery date each month.
How long before I should see improvement after switching billing companies?
Expect organization immediately and measurable direction within the first quarter. Clean claim rate and denial handling move first; days in A/R and net collection rate follow more slowly, especially where inherited A/R is large. Judge trend against your own baseline, not instant results.
What is a good denial rate for a medical practice?
There is no single verified figure for every specialty and payer mix. Vendor guidance cited in this article sets a target below 5%, while Experian Health’s 2026 survey found 40% of providers reporting that 10% or more of their claims are denied. Use those as context, agree a target with your company, and require steady movement toward it.
What are the red flags in the first 90 days with a billing company?
Late or shifting reports, denial reasons repeating without prevention work, inherited A/R left untouched, A/R over 90 days growing on new claims, unreconciled invoices, and no named contact or review cadence. Any one can be explained; a cluster cannot.
Should inherited A/R be judged separately from new claims?
Yes. Your new company did not create the old balances, but working them was part of what you hired. Track the inherited bucket on its own line — worked, collected, and identified as uncollectible with reasons — so neither side is credited or blamed for the other’s results.
Conclusion
The first 90 days decide whether a billing relationship runs on evidence or on reassurance. Freeze the baseline, track six metrics the same way every month, test the reporting against the remittances, and score the relationship formally at day 90. A good company will welcome the scorecard — it is how their work becomes visible.
If your current reporting would not let you fill in this scorecard, that gap is worth examining on its own. A free medical billing audit can show what your numbers should look like and where collections are being lost.
