Medical A/R Follow-Up Services
The short answer
Twelve firms state A/R follow-up services on their own sites, listed alphabetically with no rankings. Below: what the service includes and when to outsource it.
Accounts receivable follow-up is the unglamorous work of getting old claims paid: working aging buckets, calling payers, filing appeals, and reconciling payments. It is where revenue goes to die quietly when nobody owns it.
A/R has a half-life. Claims get harder to collect with every passing week, and eventually they become write-offs by default rather than by decision. Follow-up is the function that interrupts that decay.

What A/R follow-up actually includes
Systematic A/R work starts with aging reports segmented by payer, age, and denial status. Each bucket gets a different workflow: recent claims need status checks, mid-age claims need payer calls and appeals, and old claims need triage decisions about continued effort versus write-off.
Payment posting reconciliation is part of the job too. Underpayments hide inside posted payments, and contract variance analysis catches payers systematically paying below contracted rates. A follow-up operation that does not check for underpayments is leaving money behind.
When to outsource A/R follow-up
The clearest signal is growing A/R over 90 days combined with days in A/R climbing past 40. That pattern means claims are entering the system faster than your team can resolve them, and the backlog compounds.
It also makes sense when your billers spend all their time on current claims and the old ones never get touched. That is the normal failure mode of in-house back offices: the urgent crowds out the important until the important becomes uncollectible.
Aging buckets and what they mean
A/R under 30 days is mostly processing time. The 31 to 60 day bucket needs active status work. The 61 to 90 day bucket needs payer calls and escalation. Beyond 90 days, every claim needs an owner and a plan, because this is where write-offs begin.
Your vendor should report A/R by these buckets regularly and show the over-90-day balance shrinking. If the oldest bucket keeps growing while the vendor reports activity, the activity is not working.
Red flags in A/R follow-up vendors
Watch for these warning signs when evaluating an A/R follow-up service.
- Activity without bucket reporting. Call counts mean nothing if the over-90-day balance is not shrinking.
- No underpayment detection. If they never find contract variances, they are not looking.
- Write-offs without your approval. Every write-off should be a conscious decision, not a default.
- No escalation process. Some claims need supervisor calls and formal complaints, not just another status check.
Frequently asked questions
What is A/R follow-up in medical billing?
A/R follow-up is the systematic work of collecting on unpaid claims: reviewing aging reports, checking claim status, calling payers, filing appeals, and reconciling payments. It covers everything between claim submission and payment, and it is the function that prevents aging claims from becoming write-offs.
How much do A/R follow-up services cost?
A/R follow-up is commonly bundled into a billing company's percentage of collections, typically advertised at 4 to 10 percent. Standalone A/R cleanup projects may use flat project fees or a percentage of recovered revenue. For cleanup engagements, clarify how recovered revenue is defined and what happens to uncollectible accounts.
What is a healthy days-in-A/R number?
Healthy practices generally run 30 to 40 days in A/R, per MGMA benchmarks. Numbers climbing past 50 signal that claims are not being worked fast enough, and past 90 days the collectability of individual claims drops sharply. Track this monthly; it is one of the most honest indicators of back-office health.
When should old A/R be written off?
Write-offs should be deliberate decisions, not what happens when follow-up stops. Common candidates are claims past timely filing limits, balances below the cost of continued pursuit, and confirmed non-covered services. Every write-off should be approved, categorized by cause, and fed back into prevention so the same losses do not repeat.
Can a vendor clean up years of old A/R?
Sometimes, partially. Recovery depends on how old the claims are, whether timely filing limits have passed, and whether documentation still exists. Honest vendors will assess a sample before promising results. Be skeptical of anyone guaranteeing recovery rates on aged A/R they have not examined.
