Reducing Days in AR: Proven Tactics for OBGYN Practices

By Sanya Shukla| Last Updated at: 11th Sept '26| 16 Min Read

Overview

A $400 claim paid on day 12 and a $400 claim paid on day 95 look identical on a monthly revenue report. They are not the same claim. One funded payroll on time. The other sat inside a payer's system while the front desk moved on to the next patient. OBGYN practices carry more of these slow claims than most specialties, since maternity billing and prior authorization each add a place for a claim to stall. Median AR days crept up again in 2026, and the practices holding steady are the ones working the process, not just watching the report.

Closing that gap takes more than one fix. It means tightening the process at several points at once, front desk through denial queue, with specialized OBGYN billing support built around maternity and gynecologic claims specifically. Here is what actually moves the number.

What a Healthy AR Days Number Looks Like for OBGYN

Days in AR is calculated as total accounts receivable divided by average daily charges, with average daily charges equal to gross charges for the period divided by the number of days in that period.

A practice carrying $1,350,000 in total receivables against $45,000 in average daily charges is running at 30 days in AR, right at the strong end of the range. General benchmarks put a healthy range at 30 to 40 days, with anything under 35 considered strong performance, and net days in AR, which adjusts for contractual write-offs, typically running a few days lower than the gross figure.

OBGYN practices tend to run above that baseline by default, because global maternity packages, prior authorization delays, and payer-specific limits on ultrasounds and genetic testing all add friction a routine office visit claim never has to clear.

Fix the Front End Before the Claim Ever Goes Out

Most AR problems start well before a claim is submitted, not after.

Submit Cleaner Claims the First Time

Every claim that gets kicked back for a fixable error adds a full resubmission cycle to the AR clock. Catching those errors before submission is faster than fixing them

Make sure the global code matches what was actually provided.
Use 59400 or 59510 when the practice delivered the full antepartum, delivery and postpartum episode.
Use 59425 or 59426 for antepartum-only care, split by visit count.
For a birth after cesarean or a cesarean following an attempted VBAC use 59610 or 59618.
Don’t force these encounters into a delivery code.
Apply modifier 25 when an identifiable E/M service is billed on the same day, as a procedure.
Use modifier 59 when a service that is bundled needs to be reported as distinct.

Work Denials on a Clock, Not a Queue

Two-thirds of denied claims are never corrected or reworked at all. Most industry data shows that 70% of these denials could have been avoided from the very beginning. The practices with the shortest AR cycles turn denials around in 8 to 10 days through structured work queues, not by getting to them when time allows.

Sorting by CARC code first speeds this up considerably:

CO-197 points to a missing or expired authorization,
CO-16 points to missing information the payer will not adjudicate without,
CO-50 points to a medical necessity dispute that needs documentation rather than a resubmission, and
CO-29 points to a timely filing problem that usually cannot be appealed at all.

Each category needs a different fix, and routing them all through one generic denial workflow is what slows most practices down.

Sort denials by CARC/RARC code before assigning them, since an authorization denial, a documentation denial, and a medical necessity denial each require a different response
I will classify each denial as either administrative or clinical within forty‑eight hours after it arrives.
I will assign an owner and a firm deadline to each denial so a denial does not stay in a shared inbox.
I will ask for a peer‑to‑peer review, for every clinical denial that is linked to high‑risk services.
Track denial reasons by payer so the same mistake does not repeat claim after claim

Segment AR by Age and Act Differently at Each Stage

A claim at 20 days and a claim at 95 days need completely different responses. Treating every open balance the same way is how claims quietly age past the point of recovery.

0 to 30 days: confirm the claim was received and is processing normally
31 to 60 days: check status directly through the payer portal or a call, rather than waiting for a response
61 to 90 days: escalate to a payer relations contact and confirm nothing is missing on the practice's end
90-plus days: treat as an active recovery case with a named owner, since collection odds drop sharply the longer a claim goes unworked

As a general target, the majority of open AR, ideally 70% or more, should sit inside the 0 to 30 day bucket, with the 90-plus bucket held under 15%. A practice where a large share of AR sits past 60 days is not really looking at a collections problem. It is looking at a process gap somewhere upstream, usually at eligibility, coding, or the initial denial response.

Follow Up by Payer, Not by One Generic Process

A single follow-up cadence applied across every payer under collects from the slow ones and wastes effort on the fast ones. Most commercial contracts require payment within 30 to 45 days, and any payer running a meaningful share of claims past 60 days is not meeting that obligation. Timely filing deadlines vary just as much: many commercial plans allow 90 to 180 days from the date of service, state Medicaid programs are often tighter and differ by state, and Medicare allows a full 12 months. Missing any of these windows turns a collectible claim into an automatic, unappealable write-off, which is a very different problem than a slow one.

Track average payment turnaround separately for each major payer in the mix
Flag any payer with a growing share of claims sitting past 60 days as a contract issue worth escalating, not just a slow week
Adjust follow-up timing to match each payer’s turnaround window instead of one fixed schedule.
Keep a running list of documentation quirks so that claims stop bouncing for the same reason twice.

Make Reporting Something the Team Actually Acts On

An AR aging report that nobody reviews until month end is a record, not a management tool.

Review AR aging by bucket weekly, not just at month end
Track first-pass resolution rate, the share of claims paid without any rework, since a low first-pass rate is usually what is driving the AR number up in the first place
Calculate net collection rate (payments received divided by expected reimbursement after contractual adjustments) separately from gross collection rate to see whether the practice is collecting what it is actually owed, not just what it billed
Break AR down by provider and procedure type to catch patterns tied to specific services
Set an explicit AR days target and measure progress toward it monthly, not just at year end

When In-House Effort Stops Being Enough

Sometimes the steps above are enough on their own. Other times AR keeps climbing because the practice does not have the staff hours to work every denial and follow up with every slow payer while also seeing patients that day. At that point the issue is capacity, not process.

The Bottom Line

Days in AR is not really an accounting metric. It reflects how much friction sits between a completed appointment and the money that appointment is owed. Fix the front end, submit cleaner claims, work denials on a deadline, and follow up by payer instead of by habit, and the number moves on its own.
