Form 3618 and 3619 Timing: The Sequence That Protects Texas Medicaid Payment

Most Texas business offices know Forms 3618 and 3619 exist. Fewer treat them as a timed sequence — and that is where Medicaid revenue quietly gets stuck. These forms do not just record what happened; they gate what can happen next on the LTC Online Portal.

What Each Form Actually Does

Both are transaction notices submitted through the TMHP LTC Online Portal, but they cover different situations:

• Form 3618, Resident Transaction Notice — used for a resident whose care is paid by Medicaid or who has a Medicaid application pending. It records admissions from private pay, admissions to full Medicaid, discharges, and death.
• Form 3619, Medicare/SNF Patient Transaction Notice — used for a resident in a Medicare or skilled coinsurance stay. It records the admission and discharge of that Medicare-covered period.

The distinction matters because the LTCMI — the section that triggers medical necessity review — cannot be completed until the right transaction form is already on the portal.

The Timing Rules That Trip Facilities Up

Two timing requirements cause most of the trouble:

• For a resident who already has full Medicaid at admission, current Texas guidance directs the facility to submit Form 3618 within 72 hours of admission.
• When a resident is moving from a Medicare-covered stay to Medicaid, the LTCMI cannot be submitted ahead of the 3619 admission. The 3619 has to be on the portal first.

On top of that, the OBRA MDS itself has to reach the portal. The federal assessment is submitted to CMS and extracted to the LTC Online Portal, generally 24 to 48 hours later. Only once both the assessment and the correct transaction form are present can the LTCMI be completed and submitted.

How the Sequence Should Run

For a clean Medicare-to-Medicaid transition, the order looks like this:

• The Medicare/skilled stay ends and the 3619 discharge is filed for that period.
• Form 3618 records the admission to Medicaid (or Medicaid-pending) status.
• The OBRA MDS is submitted to CMS and appears on the LTC Online Portal 24 to 48 hours later.
• With the assessment and the transaction form both present, the LTCMI is completed and submitted.
• TMHP nurses begin the medical necessity determination.

Skip or reverse a step and the portal simply will not let the LTCMI proceed — or worse, it accepts something that later rejects, and the clock on the Medicaid application keeps running while nobody realizes the submission never actually advanced.

What Goes Wrong, and What It Costs

The failures are rarely dramatic. They are quiet sequencing errors:

• The 3618 is filed late, so the Medicaid application timeline is already compressed before the LTCMI is even attempted.
• The LTCMI is attempted before the 3619 admission and rejects, and no one checks the status until a caseworker asks.
• A demographic mismatch on the form means TMHP cannot tie it to the assessment, so the whole sequence stalls silently.
• The MDS is late to the portal, so everything downstream waits on it.

Each of these turns into the same outcome: medical necessity never starts on time, the Medicaid application drags, and days of care accrue with no payer attached to them.

How to Keep the Sequence Clean

• Treat the 72-hour and pre-LTCMI timing rules as hard deadlines, not targets — track them the way you track a billing cycle.
• Confirm the MDS has actually reached the portal before attempting the LTCMI, rather than assuming the 24-to-48-hour window has passed.
• Reconcile resident demographics — name, Medicaid ID, Social Security number — across the form and the assessment before submitting.
• Monitor form and assessment status on the portal on a schedule, so a rejection or an information request is caught in days, not weeks.

None of this is difficult in isolation. It is difficult to sustain across every admission during a staffing shortage — which is exactly when the sequence tends to break and Medicaid revenue starts slipping.
