To qualify for TCU under Medicare, a patient must have three consecutive overnight stays in Acute Care, not including 23-hour observation status. If the patient was hospitalized within the past 30 days, they may not need another three-day stay. Medicare allows for 20 days of 100% coverage for TCU or another skilled facility. At day 21, Medicare covers all but a portion (the rate changes yearly) as long as patient still has qualifiers. If the patient has supplemental insurance, the remaining cost is usually covered but staff will be happy to verify with the specific insurance carrier.
