DSDS Assessment in Missouri: How the InterRAI Level of Care Score Works

The Assessment That Controls Everything

Every state-funded long-term care pathway in Missouri — nursing home Medicaid, the Aged and Disabled Waiver, the Structured Family Caregiving Waiver, Consumer Directed Services — runs through a single clinical gate: the Division of Senior and Disability Services (DSDS) assessment. If the parent does not pass this assessment, no public program is available regardless of their financial eligibility. Understanding how it works is the single most important preparation step for Missouri families navigating dementia care.

What DSDS Measures

DSDS uses the InterRAI Home Care (InterRAI HC) instrument, a standardized clinical tool that generates an algorithmic Level of Care (LOC) score. The assessment is conducted face-to-face in the parent's home by a DSDS staff member or their designated assessor. It evaluates twelve operational categories:

Cognition — memory and recall deficits, daily decision-making limitations. For a parent with dementia, this category carries significant weight. Severe cognitive impairments can contribute up to 18 points on their own.

Activities of Daily Living (ADLs) — eating dependency, bathing assistance, transfer limitations. Each ADL deficit adds points, with complete dependency scoring highest.

Behavioral issues — wandering, resisting care, mood disturbances, psychiatric conditions. Wandering behaviors score heavily because they represent direct safety risks.

Medical treatments — wound care, catheter usage, ostomy management, alternate modes of nutrition. These categories typically apply more to medically complex patients than to early or mid-stage dementia, though they can add significant points for advanced cases.

Each category can contribute 0 to 18 points. The scores are combined algorithmically, and the total determines whether the individual meets the Nursing Facility Level of Care (NFLOC) threshold.

The 18-Point Threshold

To establish Nursing Facility Level of Care for any HCBS waiver or nursing home Medicaid pathway, the parent must score at least 18 points on the InterRAI HC. This threshold is not negotiable — 17 points means a denial, regardless of the family's subjective assessment of how much help the parent needs.

The scoring methodology applies high-weighted values to three areas that are particularly relevant for dementia families:

• Severe cognitive impairments — a parent who cannot recognize family members, cannot participate in daily decision-making, or has significant short-term memory loss scores high
• Wandering risks — documented wandering behavior or exit-seeking adds substantial points
• ADL assistance needs — particularly physical transfers, bathing, and feeding

The "Good Day" Problem

This is where families lose. The DSDS assessment is a single face-to-face visit, typically lasting 60 to 90 minutes. If the parent happens to be having a cognitively strong day — engaged, oriented, able to answer questions — the assessor's observations will reflect that moment, not the parent's typical or worst-case functioning.

The result: an LOC score that underrepresents the parent's actual care needs and fails to reach the 18-point threshold.

Families can prevent this by documenting the parent's functioning over time before the assessment:

Keep a daily care log for at least seven days. Track specific incidents: confusion about time or location, failure to recognize familiar people, assistance needed for dressing or bathing, wandering attempts, medication errors, nighttime agitation. Note the date, time, and exactly what happened.

Record the worst hours, not the best ones. The assessor needs to understand the full range of the parent's functioning. If sundowning causes severe agitation from 4 PM to 8 PM every day but the assessment is scheduled at 10 AM on a calm morning, the daily log bridges that gap.

Have the primary caregiver present and prepared to describe specific incidents. General statements ("she gets confused sometimes") carry less weight than specific examples ("on September 3rd she tried to leave the house at 2 AM in her nightgown, and on September 5th she could not remember her daughter's name for six hours").

What Happens After the Assessment

If the score reaches 18 or higher, the parent is deemed to meet nursing facility level of care. At that point, the family chooses a care pathway:

Consumer Directed Services — the parent hires and directs their own caregiver. However, DSDS will administer the SLUMS exam to verify "ability to self-direct." A score in the dementia range (1–20 for high school graduates, 1–19 for those with less education) automatically disqualifies the parent from self-directing. The family must then transition to an agency-directed model.

Agency-directed in-home services under the Aged and Disabled Waiver — personal care, advanced personal care, nurse visits, adult day care. Income limit: $1,737/month gross. Service authorization remains subject to the ADW's medical and financial eligibility requirements and state-managed capacity.

Structured Family Caregiving Waiver — a daily stipend to a live-in caregiver for a parent with documented Alzheimer's or related dementia. Capped at 300 active enrollment slots per fiscal year (July 1 through June 30); once filled, a waitlist forms.

Nursing facility placement — institutional Medicaid covers the daily rate, with the parent's income (minus $50 personal needs allowance) going to the facility as patient liability.

If the score falls below 18, the family can request a reassessment — but timing matters. Wait until the parent's condition has measurably declined and document the decline thoroughly before requesting a second assessment.

Appeal Rights

If DSDS issues a denial based on the assessment, the family has 90 calendar days from the action notice to request a fair hearing. To maintain any existing services while the appeal is pending, the appeal must be filed within 10 calendar days of the notice mailing date. The hearing is conducted by the Division of Legal Services Administrative Hearings Unit at no charge.

The Missouri Dementia & Memory Care Guide includes an assessment preparation workbook with the exact ADL and cognitive categories the InterRAI HC evaluates, a seven-day daily care log template, and instructions for presenting documented decline during the face-to-face assessment.
