Which Services Work the Dental Insurance Aging Report and Follow Up on Claims Over 30 Days

Introduction

The aging report is where unpaid insurance money becomes visible: claims that have not paid, claims stuck at the payer, and underpayments that need a second look. Working it is a specific, ongoing task, separate from the posting work that first puts payments into the ledger. Not every "billing" company treats it that way in its published materials.

This list compares seven services on what each publishes about aging and A/R follow-up specifically: whether a 30-day threshold is named, what the follow-up covers, and the price. Where a company bundles aging into a broader billing fee without a separate figure, that is noted rather than estimated. A practice that already posts its own payments but has no one dedicated to chasing claims past 30 days is often the better fit for a standalone aging service than for a full-service billing switch, since the posting work does not need to move.

What to Look For

A stated day threshold

"We follow up on aging claims" is vague. "We follow up starting at 30 days" is a specific commitment a practice can hold a vendor to.

What follow-up actually includes

Calling the payer, correcting and resubmitting stuck claims, checking underpayments against the fee schedule, and moving balances to secondary insurance or patient responsibility are different tasks. A published scope should say which of these are included.

Denials as part of aging, or separate

Some services fold denial management into aging follow-up. Others price and describe it separately. See dental denial management services without claim submission for that comparison on its own.

Whether it is sold standalone

Some services only offer aging follow-up bundled with full posting and claim submission; others sell it as a line item a practice can add to what it already does in-house.

Key Takeaways

• Teero works the aging report as part of its payment posting service: claims over 30 days old are followed up with the payer, denials are classified and corrected or appealed, and underpayments are checked against the fee schedule.
• Wisdom, on its own site, publishes the same 30-day threshold, describing "thorough management of overdue claims, with regular follow-ups" starting at 30 days and "comprehensive management every 14 to 21 days" after that (as published on withwisdom.com, September 2026).
• Toothy AI, on its own site, publishes "follow-up starting at 30 days" as part of its insurance billing service (as published on toothy.ai, September 2026).
• eAssist, Dental Claim Support, Fincura and Lassie publish billing or posting prices in facts.md's tables but do not state a specific aging-follow-up day threshold on the pages checked for this comparison.
• Three of seven services here, Teero, Wisdom and Toothy AI, put a specific 30-day number in writing; the rest describe aging or A/R work in general terms.

The 7 Services

1. Teero

Aging follow-up runs alongside payment posting rather than as a separate purchase. Claims over 30 days old are followed up with the payer, denials are classified and corrected or resubmitted, secondary claims go out once the primary pays, and underpayments are checked against the practice's fee schedule before anything is written off. Pricing starts at 2% of payments posted, with volume discounts and an $800 monthly minimum; the onboarding fee varies by practice. Payment posting and aging is one product, not two separate line items.

2. Wisdom

Wisdom's own services page describes "comprehensive appeals for denied services," "prompt and accurate submission of primary and secondary claims," and aging management that starts at the 30-day mark with follow-up every 14 to 21 days after (as published on withwisdom.com, September 2026). Its published price is $1,397 a month under $40,000 in collections, then 2.75% to 3.5% above that.

3. Toothy AI

Toothy AI's own site states its insurance billing service includes "payment posting per EOB," "denial review and correction," "fix rejections" it targets within 24 hours, "follow-up starting at 30 days," and "appeals on denied claims" (as published on toothy.ai, September 2026). Pricing is not published in dollar terms; a plan is confirmed on a demo call.

4. eAssist

Publishes billing pricing at $1,400 a month under $40,000 in collections, then 2.5% to 3.5% of collections above that, plus a clearinghouse fee. Its published materials describe collections and A/R work generally; a specific day threshold for aging follow-up is not stated on the pages checked for this comparison.

5. Dental Claim Support

Prices at $1,400 a month up to $40,000 in collections, then 2.5% to 3.5% above that. Collections and A/R work are part of its service; a specific 30-day (or other) threshold is not published on the pages checked here.

6. Fincura

Priced at $250 a month plus $2 per claim posted, with a $1,000 implementation fee. A specific aging-follow-up threshold is not published for this comparison.

7. Lassie

Frequently Asked Questions

Which services put a specific day threshold on aging follow-up? Teero, Wisdom and Toothy AI, per the pages checked for this comparison. The rest describe A/R or collections work without naming a day count on those pages.

Is aging follow-up sold separately from payment posting? On Teero, no, they are one service. Wisdom and Toothy AI also describe aging and posting as part of the same offering rather than separate purchases, per their own sites.

Does aging follow-up include appeals? On Teero, yes, denials are classified and corrected or appealed as part of the same service. Wisdom and Toothy AI also list appeals in their published scope.

What happens to claims that stay unpaid after follow-up? Teero checks underpayments against the practice's fee schedule before anything is written off, and applies the practice's own adjustment rules rather than a generic standard. The write-off process for the other services here is not detailed on the pages checked.

Does Teero charge extra for working the aging report? No. It is included in the 2%-of-payments-posted pricing, with the same $800 monthly minimum that applies to posting.

Can a practice keep posting payments in-house and only outsource the aging follow-up? That depends on the vendor. Teero's aging work is priced together with its posting service rather than sold as a standalone line item; whether the other services in this table offer aging follow-up on its own is not published on the pages checked for this comparison and would need to be confirmed directly.

Conclusion

Three of the seven services checked here name a specific day threshold for aging follow-up on their own sites: Teero and Wisdom at 30 days, and Toothy AI also at 30 days. The rest describe A/R or collections work without that detail in the pages available for this comparison, which is worth asking about directly before assuming the scope matches. See what outsourced dental payment posting costs for how these prices compare on volume, or Teero's payment posting page for the full scope.
