- By mail or fax: Download the paper application (IM-1SSL) from dssmanuals.mo.gov. Mail to: Family Support Division, P.O. Box 2700, Jefferson City, MO 65102. Or fax to 573-526-9400. Keep a copy of everything you submit.
Who needs a supplemental form
Most applicants submit just the standard application form (IM-1SSL). However, you must also complete the Supplemental Form (IM-1ABDS) if any of the following apply to you or a household member:
- Age 65 or older
- Blind or disabled
- Receiving Social Security benefits (any type)
- Living in a nursing facility or other medical institution
- Have Medicare or VA healthcare coverage
This supplemental form is required because these categories use a different eligibility methodology (non-MAGI) with income and asset tests that differ from the standard MAGI-based MO HealthNet rules. The form is available at dssmanuals.mo.gov or at any FSD Resource Center.
How long MO HealthNet takes to process
Per the MO HealthNet Division's application page, Missouri processes most applications within 45 days under the federal standard at 42 CFR 435.912. If a disability determination is required, the timeline can extend to 90 days.
If you do not receive any notice from the Family Support Division within 45 days, contact your local FSD Resource Center. If approved, you will receive a MO HealthNet ID card and information about your coverage type in the mail.
