Accounts Receivable Follow-up Services
Accounts receivable follow-up works unpaid insurance balances by age so claims are status-checked, corrected, transferred, or escalated before timely-filing windows close. Vector Medical Billing runs the insurance A/R queue inside your EHR from Jamaica, NY, for all 50 states. *Under 35 days is Vector’s published strong benchmark; your result depends on specialty and payer mix.
After submission
What accounts receivable follow-up is
A/R follow-up is the ongoing work on open insurance balances that have not paid, denied with a worked path, or transferred to the next responsible party.
After claims submission and payment posting, unpaid claims age. If nobody checks status, money sits until the payer’s timely-filing limit ends. Follow-up is that daily and weekly queue — not a one-time cleanup project.
Adjudicated denials with CARC detail route to denial management. Very old balances that a prior vendor abandoned are a different engagement: old A/R recovery.
Days in A/R — what the number means
Days in A/R estimates how long, on average, it takes to collect after charges enter receivables.

How it is usually calculated
A common practice formula is total accounts receivable (often net of credits) divided by average daily charges. Exact system reports differ by EHR; the important part is using one consistent method month to month.
Vector Medical Billing’s published position: under 35 days is a strong result; over 50 usually points to a follow-up problem rather than only a payer problem. That is Vector’s published benchmark language, not a guarantee for every specialty.
Industry ranges (labeled)
Physician-practice KPI summaries often cite roughly 30–40 days as an optimal days-in-A/R range, and target A/R over 90 days below about 10% of total A/R (see the MGMA Top KPIs white paper summarizing AAFP and related targets). MGMA also tracks aging buckets such as 0–30 through 120+ days and treats a high share in 120+ as revenue at risk.
*Industry benchmarks for comparison — not Vector client averages.
Aging buckets and what follow-up does in each
Standard buckets are 0–30, 31–60, 61–90, 91–120, and 120+ days. The action changes as the claim ages.
| Bucket | Typical focus | Follow-up action |
|---|---|---|
| 0–30 days | Recently billed; many payers still adjudicating | Confirm acceptance into the payer system; watch for early rejections; note secondary timing |
| 31–60 days | Should be moving toward payment or a clear status | Payer status check; resolve holds; transfer to secondary when primary has paid |
| 61–90 days | Risk rising; denials and lost claims show here | Investigate unpaid vs denied; route denials to the denial queue; escalate stalled claims |
| 91–120 days | Timely-filing pressure on many commercial plans | Priority work; document contacts; correct and resubmit only with filing proof where needed |
| 120+ days | High write-off risk if untouched | Final push on workable items; decide close, patient transfer, or handoff to old-A/R scope |
MGMA reports aging as a share of total A/R across these buckets. A healthy book skews toward 0–30; a large 120+ share usually means follow-up stopped or denials were never worked.
Insurance A/R vs patient A/R
Both sit on the ledger. Follow-up methods are not the same.
Insurance A/R
Open payer balances after submission. Work is status inquiry, corrected claim, secondary billing, or denial handoff. This page is mainly about insurance A/R follow-up.
Patient A/R
Balances that remain after insurance posts patient responsibility. Those move through patient statements and collections — not payer phone queues pretending to be patient billing.
How Vector Medical Billing works the A/R queue
Aging reports drive the work. Claims are not left until month-end close.
1
Pull aging
Insurance A/R by payer, amount, and bucket. Priority to high dollars and near timely-filing dates.
2
Status check
Clearinghouse and payer portals: paid, pending, rejected, denied, or never received.
3
Act
Correct and resubmit, bill secondary, route denials, or document payer contact with a next date.
4
Close or transfer
Confirm payment posts, move true PR to patient A/R, or close non-workable items with a reason.
Timely filing is why aging cannot wait
Each payer sets a filing window from the date of service or from primary payment. Miss it and recovery options shrink sharply.
Watch the clock by payer
Commercial, Medicare, and Medicaid windows differ. Follow-up prioritizes claims approaching the limit for that plan.
Keep submission proof
Clearinghouse acknowledgments matter when a payer says the claim was never received or was late.
Late without proof rarely recovers
That is why prevention is earlier status work — not a letter after the window closed. See also denial management on timely-filing denials.
What A/R follow-up is not
Clear boundaries keep the right specialist on the right balance.
Not denial appeals
When the remittance shows an adjudicated denial, the item moves to denial management for corrected claim or appeal work. Follow-up finds that status; it does not replace CARC triage.
Not old A/R recovery
Current-book follow-up is continuous. Recovering a large abandoned backlog from a prior biller is scoped separately under old A/R recovery.
Not patient statements alone
Statements collect patient responsibility after insurance. Payer status work on unpaid insurance claims is a different queue.
How A/R follow-up is priced
On a full-cycle engagement, insurance A/R follow-up sits inside the monthly percentage of collections. Standalone A/R vendors sometimes quote per claim or per FTE; Vector’s published model folds the queue into billing.

Where the work sits
Submission starts the clock. Posting clears paid lines. Denial management works refused lines. A/R follow-up works everything still open so days in A/R stay controlled.

A/R follow-up questions
Straight answers tied to the sections above.
What is accounts receivable follow-up in medical billing?
Working open insurance balances by age: confirm status, correct or resubmit when needed, bill secondary, hand denials to denial management, and keep claims from aging past timely filing.
What is a good days-in-A/R benchmark?
Vector publishes under 35 days as strong and over 50 as a follow-up warning. Broader practice KPI summaries often cite about 30–40 days as optimal. Specialty and payer mix still move the number.
How do aging buckets work?
Open A/R is grouped by age — commonly 0–30, 31–60, 61–90, 91–120, and 120+ days. Follow-up actions get more urgent as claims move into later buckets.
How is A/R follow-up different from denial management?
Follow-up works unpaid and pending claims. Denial management works adjudicated refusals with reason codes. Status work often discovers the denial; appeal work belongs in the denial queue.
How is it different from old A/R recovery?
Follow-up is continuous work on the current book. Old A/R recovery is a scoped project on aged balances that were neglected or handed over from a prior billing setup.
Is A/R follow-up an extra fee?
No on the full-cycle monthly engagement. It is inside the billing percentage of collections.
Do we change our EHR?
No. The queue runs in Athenahealth, eClinicalWorks, Tebra, AdvancedMD, DrChrono, NextGen, CareCloud, Practice Fusion, CureMD, Office Ally, or another system confirmed before start.
