Hospice Eligibility Requirements: PPS Scores, FAST Staging, and What Doctors Look For

A parent's doctor says "we should discuss hospice," and the first question is always the same: does my parent qualify? Hospice eligibility is not subjective. It follows specific clinical criteria that two physicians must independently certify.

The Core Requirement

Under Medicare guidelines, hospice eligibility requires a terminal prognosis of six months or less if the disease follows its expected course. Two physicians must certify this independently: the parent's attending physician and the hospice agency's medical director.

The initial certification must be obtained within two calendar days of the start of hospice care. This certification is not a guarantee of death within six months — it is a clinical judgment based on disease trajectory.

The Palliative Performance Scale (PPS)

The Palliative Performance Scale is the primary clinical tool used to assess functional decline for most diagnoses. It evaluates five domains — ambulation, activity level, self-care ability, intake, and consciousness — on a percentage scale from 100% (fully functional) to 0%.

For hospice eligibility, a PPS score of 40% or lower is the general threshold. At PPS 40%, a parent is mostly bedbound, unable to do most activities, needs extensive assistance with self-care, has reduced food and fluid intake, and may be drowsy or confused.

The PPS is used for cancer, organ failure, stroke, and most other terminal diagnoses. Dementia has its own staging tool (see FAST scale below).

The FAST Scale for Dementia

For Alzheimer's and other dementias, Medicare uses the Functional Assessment Staging Tool (FAST) rather than the PPS. Hospice eligibility requires a FAST score of Stage 7A or higher, plus at least one documented secondary complication in the past 12 months.

FAST Stage 7 substages:

• 7A — Speech limited to about six intelligible words per day
• 7B — Vocabulary reduced to a single word or unintelligible sounds
• 7C — Unable to walk without physical assistance
• 7D — Unable to sit upright without support
• 7E — Unable to smile
• 7F — Unable to hold head up independently

Required secondary complications (at least one):

• Recurrent infections resistant to treatment — aspiration pneumonia, urinary tract infections, or septicemia
• Progressive weight loss exceeding 10% of body weight over six months, or serum albumin below 2.5 g/dL
• Multiple Stage 3 or 4 pressure ulcers that do not heal despite proper care
• Advanced heart failure or COPD accelerating functional decline

Physicians often delay hospice referrals for dementia because the decline trajectory is harder to predict than cancer. Families who understand the FAST staging criteria can have more informed conversations with their parent's doctor about whether the clinical thresholds have been met.

What Happens After Certification

Once both physicians certify eligibility, the family signs a hospice election statement. This begins an initial 90-day benefit period, followed by a second 90-day period, then unlimited 60-day periods. Starting at the third period, a hospice physician must conduct a face-to-face examination to recertify continued eligibility.

If a parent's condition stabilizes or improves, they can be discharged from hospice. They can also voluntarily revoke hospice at any time with a written statement and immediately return to standard Medicare coverage.

When to Push for a Referral

Many families wait too long. The median length of hospice stay in the US is under 20 days — far shorter than the six-month benefit period allows. Watch for these patterns:

• Three or more hospitalizations in six months for the same condition
• Progressive weight loss despite adequate nutrition support
• Increasing dependence in daily activities (bathing, dressing, toileting)
• The parent or their doctor shifting language from "treatment" to "comfort"
• A PPS score trending toward 40% or a FAST score approaching Stage 7
