Early intervention billing software for Part C teams

Why EI billing breaks software built for clinics

A clinic visit is a simple billing event: a patient arrives at a known address, one payer is on file, and the charge is generated at the front desk on the way out.

Early intervention is none of those things. The session happened in a family’s kitchen or a childcare centre. The provider drove there and will not see a desk until Thursday. The service may be billed to a state Part C programme, to Medicaid, to a commercial plan, or to some sequence of the three depending on how your state administers the programme. And a growing number of states require the visit itself to be electronically verified before any of it counts.

Software that assumes the clinic model handles this by making somebody re-enter it later, which is where both the errors and the evenings go.

The charge comes from the visit

The billable record is created where the session happened, not reconstructed afterwards. The visit note carries the minutes for each timed service, the place of service for the setting the session actually occurred in, and the provider who delivered it.

Units are computed from those documented minutes under the rule the relevant payer contract uses — which in early intervention is frequently not the same rule across the payers on a single caseload. The arithmetic and the difference between the two rules is covered in the 8-minute rule; the practical point here is that the rule is a per-payer setting rather than a property of the programme.

Place of service is the one that quietly costs money. A home-based session billed under an office place of service is denied, and it is denied after the fact, in bulk, weeks later. Recording it on the visit is the only way it survives a caseload.

Visit verification and the charge are one record

Where your state requires electronic visit verification, the verification and the billable record must describe the same visit or the claim fails on a technicality that has nothing to do with the therapy delivered.

Capturing both from the same session record is the point — the parent page explains what EVV actually requires and what it does not. What matters for billing is that there is no second system to reconcile against, because a reconciliation between two systems is a job somebody has to do every month forever.

The export, and what we do not do

Finished charges leave as CSV or as completed CMS-1500 field data for whoever submits on the practice’s behalf. The fields the form needs, and the boxes that decide whether a technically complete claim gets paid, are covered in the CMS-1500 field guide — Box 23 for the authorization, Box 24B for the setting, Box 32 where the service facility differs from the billing address, which in home-based work it always does.

MegAligna does not transmit claims to payers. Agencies that submit electronically today should read that as the limitation it is.

Authorizations, on the same clock as the sessions

Early intervention runs on authorized service quantities the same way ABA does, and it runs out of them the same way: silently, mid-period, with sessions already delivered against a pool that emptied two weeks ago.

Authorized units burn down against delivered sessions as they are documented, so the number a coordinator sees is current rather than reconstructed at month-end. An expired authorization that is still on file renders perfectly onto a claim and denies.
