AI insurance payment posting for CareStack

PearlFlow integrations · November 14, 2026

CareStack is a cloud practice management system, and it gives offices both manual posting and rules-based ERA posting. As CareStack puts it, once the rules are set up, manual work is only needed for exceptions. Those exceptions still need a person.

This page covers what CareStack says about insurance posting, where the remaining work sits, and what PearlFlow does for a CareStack office.

How insurance payments are posted in CareStack today

Manual posting. CareStack says you can post payments for a patient’s services at the claim level or at the code level (CareStack). Its revenue cycle guide adds that you can post payments and adjustments at the line level, mark claims and procedures for appeal, and capture interest payments (CareStack).

ERA posting. CareStack lets you set up remittance posting rules and auto-post ERAs, with manual work only for exceptions (CareStack). Its claims page says automated ERA posting is available for payments made by electronic funds transfer (EFT), and that claims update with statuses from the clearinghouse (CareStack).

Exact screens and settings depend on your CareStack version and setup. CareStack’s help center has the current steps.

Where the time goes

Rules-based posting works best on clean, expected payments. The rest falls to staff:

Exceptions. Short payments, denials, and anything outside your posting rules wait for a person.
Non-EFT payments. Paper checks come with paper EOBs that have to be entered by hand.
Portal-only payers. Some payers post EOBs on their website instead of sending an ERA. Someone has to download them and post them.
Appeals and interest. Denied lines need a reason recorded and a follow-up. Interest payments need to be captured separately.

Common posting errors

Posting at the claim level when the EOB reduced one procedure, so the shortfall can’t be traced.
Posting a payment from a portal EOB, then again when the ERA arrives.
Treating the difference between billed and allowed as patient balance instead of a contractual write-off.
Letting exceptions sit unworked because they’re mixed in with everything that posted.

What PearlFlow does for a CareStack office

PearlFlow covers the whole nightly loop, not only the clean ERAs:

Claims out. It sends the day’s claims through the clearinghouse your office already uses.
Remittances in. Each night it collects remittances from all your payers, including payer portals and paper EOBs you scan.
Matching. It matches each payment to the open claim.
Posting. It posts into CareStack line by line: insurance paid, write-off, and patient portion.
The EOB. It can attach the EOB to the patient’s record.
A safe stop. When the numbers don’t add up, it posts nothing and puts the claim on the morning list with the reason.

The morning list comes by email and on the dashboard, which also shows every claim, what was posted, and the EOB behind each payment. Posting is customized the way your staff prefers.

Questions CareStack offices ask

Do we need to change how we use CareStack?

No. You keep CareStack and your clearinghouse. PearlFlow posts into CareStack the way your team does.

We already have ERA posting rules. Why add PearlFlow?

Rules handle the payments that arrive as expected. PearlFlow also handles paper and portal EOBs, checks every payment against its claim, and turns the exceptions into one short list with reasons.

Does PearlFlow post line by line or by claim?

Line by line, procedure by procedure, the way the EOB lists it.

Do you sign a BAA?

Yes, before any data is shared.
