Overview
Form 8615 is the HHSC log for on-site and off-site ISS, the service that replaced day habilitation in Texas in 2023 (our guide on what ISS is in Texas covers the rules). The form lives on the HHSC forms site, and HHSC updated it in June 2026. Most ISS programs still fill it by hand on Friday from a paper sign-in sheet, which is where the time in and out, the ratio, and the activity initials drift apart from what happened.
Sereniq makes the day the record. Van in opens an on-site block for everyone on the van. Trip out starts a community outing with the staff and the people who went, and writes their counts onto every member as the ratio the group ran. Everyone back closes it. Day done ticks the activities once for the group, writes the day once, and each person gets their own summary. The weekly log is already filled when the office opens it.
The print follows the June 2026 Form 8615 layout page for page: the HHS lockup, the on-site and off-site sections, two time in and out blocks per day, ratio and group size on the off-site rows, the activity grid with staff initials, and the community locations and occurrences. It sits beside every HHSC form Sereniq prints. The daily summary prints on a separate page marked Not part of Form 8615.
Form 8615 is also the paper behind the bill. When a placing agency’s monthly bill goes out from Sereniq’s ISS billing, each person’s Form 8615 weeks ride along as their own PDF, and an attended day with no activity recorded holds the bill back until it is fixed. Sereniq does not submit Medicaid claims; the placing HCS or TxHmL agency bills against the log it receives.
What does HHSC Form 8615 record?
Form 8615 records one individual's ISS service events for a week: the date, the place of service, time in and time out for up to two events per day in each setting, the activities worked on from the form's grid, the name and signature of the staff member who provided the service, and on off-site days the staffing ratio, the number of people in the group, and each community location.
| Field on the form | Where Sereniq gets it |
|---|---|
| Date and place of service | The attendance board, per day |
| Time in and time out, on-site | The on-site block that check-in opened |
| Time in and time out, off-site | The trip, from Trip out to Everyone back |
| Staffing ratio on off-site rows | The staff and group counts the trip ran |
| Number of people in the group | The trip roster |
| Activities worked on | Day done: ticked once for the group, adjusted per person |
| Community locations | The saved place picked at Trip out |
| Special or unusual occurrences | Typed on the log by staff |
| Service provider name and signature | The staff member who wrote the note; a saved e-signature is stamped where they recorded the block |
What is the 14-day rule for Form 8615?
HHSC's Form 8615 instructions say the log must be completed within 14 calendar days after the service it documents. Sereniq dates each weekly log from the first attended day of the week and shows Due in N days, Due today, Overdue by N, or Complete on every row, so the office sees what is owed before the deadline passes. Managers and the staff who worked that week are reminded three days before a log is due and again when it is overdue.
A late log is a billing problem for the placing agency as well as a survey finding for the program, because the agency bills Medicaid against it. In Sereniq, an attended weekday with no activity recorded also holds back that agency's bill until someone fixes it.
What does the off-site section need that the on-site section does not?
The off-site section of Form 8615 adds three things to every event: the staffing ratio that was run, the number of people in the group, and a description of each community location. HHSC's HCS billing requirements also call for the individual's level of need on off-site events. Sereniq writes the ratio and group size onto every member of a trip at Trip out, and the saved place becomes the location.
| Requirement | On-site | Off-site |
|---|---|---|
| Time in and time out per event | Yes | Yes |
| Activities and implementation plan objectives | Yes | Yes |
| Staff name and signature | Yes | Yes |
| Staffing ratio | No | Yes |
| Number of people in the group | No | Yes |
| Community location | No | Yes, each one |
| Level of need | No | Yes |
Is HHSC Form 8615 the same as IRS Form 8615?
No. IRS Form 8615 is a federal tax form for a child's unearned income. HHSC Form 8615 is a Texas Health and Human Services form, the HCS and TxHmL on-site and off-site ISS service delivery log. If you run or bill an ISS program in Texas, you want the HHSC form, which is in the 8000 to 8999 series on the HHSC forms site.
Form 8616 is its companion: the in-home ISS service delivery log, used when ISS is delivered in the individual's own residence. Sereniq prints Form 8615 for on-site and off-site ISS and does not print Form 8616.
Can an ISS provider use its own log instead of Form 8615?
Yes. HHSC's instructions say an HCS or TxHmL program provider may create its own tool for documenting on-site and off-site ISS as long as it has every required element of Form 8615, and HHSC allows handwritten or electronic logs if they are legible. Sereniq keeps the state's own layout anyway, because a surveyor who asks for the form gets the form.
How does Sereniq print Form 8615?
Sereniq prints the June 2026 Form 8615 page for page: the HHS lockup, both the on-site and off-site sections, two time in and time out blocks per day, ratio and group size on off-site rows, the activity grid with staff initials, and community locations and occurrences. Print one person's week, every log in the week packet, or let the placing agency's monthly bill carry every Form 8615 week for the people it places.
The daily summary staff write at Day done prints on a separate page marked Not part of Form 8615, never on the state form. Every print is recorded in the audit log as a disclosure, with who printed what and when.
What you get
- Time in and time out filled from the four-tap attendance board, never typed twice
- Off-site ratio and group size written by the trip, not by hand
- Activities ticked once for the group at Day done, then adjusted per person
- Initials bound to the staff member who made them
- Due in N days, Due today, Overdue, or Complete on every weekly log
- Printed on the June 2026 Form 8615 layout, page for page, HHS lockup included
- Form 8615 weeks attached to each placing agency's monthly bill
- Every print recorded as a disclosure in the audit log
- Ask Sereniq answers whose log is due or overdue, from the record
What agencies ask before switching.
Who fills out Form 8615?
The licensed ISS provider that delivered the on-site or off-site service. A staff member who provided the service signs it, and the provider keeps a copy in the individual's record. In Sereniq, the staff member who writes the note at Day done is the service provider on the form.
How many service events fit on one Form 8615?
Two per day in each setting. HHSC says a new form is needed when there are more than two service events in one day. Sereniq fills the two time in and time out blocks per day per setting from the attendance board.
Does Form 8615 cover in-home ISS?
No. In-home ISS is documented on Form 8616. Sereniq prints Form 8615 for on-site and off-site ISS and does not print Form 8616.
Does Sereniq submit Form 8615 to HHSC or TMHP?
No. Form 8615 is kept in the individual's record and shown to surveyors; it is not submitted. The placing HCS or TxHmL agency bills Medicaid against it. Sereniq attaches each person's Form 8615 weeks to the placing agency's monthly bill as a PDF so the agency has the logs behind what it is billed.
What happens if a log is late?
Sereniq shows Overdue by N days on the row and holds back the placing agency's bill while an attended day in an editable week still has no activity recorded. Nothing pads or rounds the times, and nothing fills a log for you.
