We reviewed the A/R aging report for a pediatric group running $27M in annual revenue.
66% of their total A/R sat past 90 days.
Their Days in A/R was 114.
The MGMA benchmark is 30.
Here’s the thing: their billing team was not failing. Claims were going out, charges were being submitted, and collections were occurring every month. The practice was not losing revenue.
It was losing time.
And in A/R, time has a specific dollar value.
In this guide, you’ll learn:
- Why 66% past 90 days is not a billing problem
- How recoverability math actually works, and what it costs when you ignore it
- The four operational conditions driving aged A/R in most pediatric practices
- The four-step recovery method that moves Days in A/R from 114 toward 75 in 90 days
- How to staff the recovery so Month 2 does not collapse under its own follow-up load
Let’s get into it.
The Recoverability Curve Is the Number Most CFOs Are Not Running
When a claim sits past 90 days, most billing teams treat it as a follow-up problem.
It is not.
It is a recoverability problem.
Here is how the math works:
| Aging Bucket | Typical Recoverability Range |
|---|---|
| 0–60 days | 95–98% |
| 60–90 days | 85–90% |
| 90–120 days | 60–75% |
| 120+ days | 25–50% |
A claim worth $500 at 60 days is worth $250 to $375 at 120 days.
Not because the payer reduced the payment. Because the probability of collecting it at all has dropped by half.
For a practice with $5.71M sitting in the 90+ day bucket, every additional 30 days of inaction compounds migration into the 120+ band. At that level, a 10-point decline in recovery rate equals $571,000 in write-off exposure.
That is not a billing cycle issue. That is a working capital decision.
Why 66% Past 90 Days Is a Conversion Problem, Not a Volume Problem
Most PE portfolio leaders look at an elevated Days in A/R figure and ask the same question: do we need more billing staff?
The answer is almost always no.
A practice reaching $27M in annual revenue with 114 Days in A/R is not under-billing. It is under-converting. The charges are going out. The cash is not coming back fast enough.
Here is a simple calculation to see what that gap means in working capital terms:
At the MGMA 30-day benchmark, a practice generating $2.28M per month in charges should carry roughly $2.28M in total A/R.
This practice was carrying $8.65M.
The difference, $6.37M, is working capital tied inside the aging cycle. That is money already earned, already billed, and sitting in a queue instead of a bank account.
For a platform, that gap has a direct effect on acquisition capacity, debt service, and operating leverage.
The Four Conditions Driving 90+ Day Concentration in Pediatric Practices
Before staffing a recovery, you need to know what is actually causing the backlog.
In most pediatric engagements, four conditions are working against each other at the same time.
1. Aging in Place
Claims are submitted. Then they sit.
Follow-up cadence is not matching the incoming volume. As new claims stack up, older ones migrate across aging bands without anyone actively working them. By the time the 90-day mark arrives, hundreds of claims have crossed into a recoverability range where collection requires significantly more effort per dollar recovered.
2. Denial Escalation Lag
Pediatric practices carry a specific set of high-frequency denial triggers: vaccine administration bundling, developmental screening documentation, prior authorization requirements on certain payer contracts, and credentialing-related holds on newly added providers.
When these denials pile up in a queue rather than getting worked daily, each one ages independently. An authorization-denied claim at 45 days is fixable. The same claim at 110 days is borderline.
3. No Boundary Defense at 90-120 Days
The 90-120 day window is where recoverability drops from 85-90% to 60-75%.
Most practices do not run a specific defense at this boundary. Claims cross into the 120+ band during normal follow-up cycles, and by the time the billing team gets to them, A/R recovery requires appeals, contractual review, or write-off decisions that should have been made 60 days earlier.
4. No Real-Time Visibility
If you are running your A/R performance off monthly reports, you are already 30 days behind.
By the time a report shows that 90+ day concentration has climbed from 55% to 66%, two full follow-up cycles have passed. The damage is already compounding.
Without a Cash Velocity Dashboard tracking five operational indicators daily, the first signal of deterioration is usually a cash flow squeeze, not a metric on a dashboard.
Why Medicaid and CHIP Payer Mix Make This Worse for Pediatric Practices
This is specific to pediatrics, and it matters.
Pediatric payer mix skews heavily toward Medicaid and CHIP. Both programs carry longer adjudication timelines than commercial payers and higher rates of authorization-related denials.
A commercial payer denial on a claim submitted in January typically resolves in February or March with one appeal.
A Medicaid denial on the same claim can sit in a state-specific appeals process through April, May, or June, crossing two aging bands during normal resolution cycles.
When 40-60% of a pediatric practice’s payer mix is Medicaid or CHIP, the baseline recoverability curve for the 90-120 day bucket is closer to the 60% floor than the 75% ceiling.
Most recovery models do not account for this. They apply a single recoverability percentage across the full 90+ day pool without segmenting by payer.
That produces an overestimate of what is actually recoverable, which leads to staffing shortfalls when the engagement starts and actual collections come in below projection.
The Four-Step Recovery Method
Volume-based follow-up, where a billing team works through claims in aging order without segmentation, produces low recovery value per hour.
Here is why: a $50 co-pay from 95 days ago gets the same follow-up time as a $4,200 inpatient claim from the same period. The recoverability math on both is similar, but the dollar impact is not.
An effective recovery method segments the aging pool before anyone picks up the phone.
Step 1: Segmentation
Divide the full A/R pool into discrete work queues by four variables: aging band, payer, denial category, and dollar value.
This produces queues that can be staffed, tracked, and measured independently. You can see the throughput per queue, the resolution rate per payer, and the migration rate at the 90-120 day boundary all at once.
Step 2: Risk-Based Prioritization
Rank the queues by recoverability risk and dollar exposure.
90-120 day claims with high-dollar balances and correctable denial reasons sit at the top. 0-60 day claims with low balances and clean submission status sit at the bottom. The recovery effort concentrates where the time-sensitive recoverability window is narrowing fastest.
Step 3: Taskforce Deployment by Aging Bucket
Staff each queue with A/R resources matched to the complexity of the work:
| Aging Bucket | FTE Type | Target Timeline |
|---|---|---|
| 30–60 days | Mid-level A/R | Under 30 days to resolution |
| 60–90 days | Senior A/R | Under 45 days to resolution |
| 90–120 days | Senior A/R + Team Lead | 60–120 day cleanup |
| 120+ days | Senior A/R + Legal review | Contractual recovery |
Step 4: Cash Velocity Dashboard
Track five indicators daily: Days in A/R, percentage of A/R over 90 days, net collection rate, claim lag days, and EFT penetration rate.
Daily tracking means a payer going slow on a category of claims gets flagged inside the same week, not at the end of the month after the pattern has compounded into a new aging band.

The Staffing Problem Nobody Plans For: The Month 2 Follow-Up Load
This is where most recovery attempts stall.
Month 1 of a 90-day engagement attacks the backlog directly. Senior A/R specialists work the highest-dollar 90+ accounts, payer escalations go out, and resolution activity starts moving claims out of the 90+ bucket.
Then Month 2 starts.
All of those Month 1 resolutions generate a return wave of follow-up activity: denial responses from payers, appeal tracking, call-back management, resubmission cycles. That follow-up load consumes 25-30% of team bandwidth.
If you staffed for the backlog but not for the follow-up wave, Month 2 throughput drops and new claims start crossing the 90-day boundary while the team is occupied managing the returns from Month 1.
The FTE model has to account for this in advance.
For the engagement in this analysis, Month 1 required 11 A/R specialists. From Month 2 onward, the model scaled to 15 specialists to absorb the follow-up load without sacrificing new backlog throughput. With team lead and QA analyst roles included, total deployment reached 13 FTEs in Month 1 and 17 FTEs from Month 2 through Month 3.
Getting to that number requires sizing the claim inventory before staffing. At an average charge value of $175 per claim, a $5.71M 90+ day balance represents approximately 32,600 claims. At 770 claims cleared per A/R associate per month (35 claims per day, 22 working days), clearing the backlog inside four months requires 11 specialists on Day 1, before the follow-up load is even factored in.
Phase-Based KPI Targets: Why 30 Days Is Not the Starting Goal
A practice at 114 Days in A/R cannot credibly commit to reaching the MGMA 30-day benchmark in 90 days.
If that is the stated target, the first monthly KPI review will show a miss. That miss creates doubt about the engagement model, pressure to cut corners on the recovery methodology, and sometimes early disengagement before the backlog is cleared.
Phase-based targets work because they are achievable and auditable.
| Phase | Checkpoint | Days in A/R Target | 90+ Day Concentration Target |
|---|---|---|---|
| Baseline | Day 0 | 114 days | 66% |
| Month 1 | Day 30 | 95 days | Trending down |
| Month 2 | Day 60 | 85 days or under | Under 55% |
| Phase 1 close | Day 90 | 75 days | 45% or under |
| Phase 2 close | Day 180 | 60 days or under | 35% or under |
| Long-term | Beyond 180 | Approach 45 days | Under 15% |
At the Day 90 Phase 1 target, the working capital picture has already changed materially. Moving from $8.65M in total A/R at 114 days to the 75-day equivalent unlocks approximately $3M in cash that was previously locked in the aging cycle.
At the Phase 2 target of 60 days by Day 180, that figure reaches $4.1M.
Those are numbers a PE Operating Partner can run against a portfolio timeline.
The Governance Model That Keeps the Recovery from Reversing
The most common failure mode after a successful 90-day recovery is not a billing problem.
It is backlog rebuild.
Collection velocity improvements during an engagement erode over six months if the governance structure does not stay in place. Without daily KPI tracking, weekly operations reviews, and a visible escalation path for payer anomalies, the patterns that produced the original backlog reassert themselves.
The governance model that prevents this runs on four cadences:
- Daily standup: Team lead and QA/KPI analyst review claim throughput, escalation queue, and blockers every morning.
- Weekly ops review: BillingParadise and a client-side stakeholder review aging movement, denial patterns, and payer hotspots.
- Bi-weekly dashboard review: The Cash Velocity Dashboard’s five indicators are reviewed against phase targets with RCM leadership.
- Monthly steering review: Executive stakeholders review phase-target attainment and calibrate FTE allocation for the next 30 days.
The Cash Velocity Dashboard is the mechanism that makes the daily standup actionable. Without it, the standup is a status meeting. With it, the team knows by 9 AM whether any of the five indicators deviated from their previous day’s trajectory, and why.
What 75 Days in A/R Means at Day 90
For a practice generating $2.28M per month in charges, reaching 75 Days in A/R means carrying approximately $5.7M in total A/R.
That is down from $8.65M at the start of the engagement.
The difference, $2.95M, has moved from the aging cycle back toward accessible working capital through a combination of direct claim resolution, payer settlements, and improved incoming claim velocity.
At the 45% optimistic recovery rate on the original $5.71M 90+ day balance, collections from that bucket alone reach $2.57M.
At the conservative 35% rate, the figure is $1.99M.
For a PE portfolio carrying a pediatric platform with $15-100M in annual revenue across multiple locations, that calculation runs at scale. A platform with four practices, each carrying a similar aging profile, is looking at a potential $8M-$10M in combined working capital recovery from a structured engagement across all locations.
That is the business case for running the recoverability method.
The Bottom Line
66% past 90 days is not a billing capacity problem.
It is a conversion velocity problem, and it has a specific dollar value at every point in the aging cycle.
The four conditions driving it in pediatric practices, aging in place, denial escalation lag, no boundary defense at 90-120 days, and no real-time visibility, are all addressable with a structured approach.
The recovery requires the right diagnostic, the right staffing model (including the Month 2 follow-up load), and a governance structure that prevents the backlog from rebuilding after the engagement ends.
The recoverability math does not change. The only variable is when you start running it.
