Observation status caused a skilled-nursing denial. Can I appeal?
Yes, but the argument depends on plan type: Original Medicare usually requires a qualifying three-day inpatient stay for SNF coverage, while many Medicare Advantage plans waive or modify that rule. Appeal by proving the hospitalization status, the plan's SNF rule, and any MA plan language that waives the three-day requirement.
What to do, in order
- Step 1
Get the hospital status record
Ask for the admission order, observation notices, inpatient order, discharge summary, and dates and times.
- Step 2
Identify the payer
Original Medicare, Medicare Advantage, Medicaid, and commercial plans treat observation status differently.
- Step 3
Read the SNF rule in the plan document
For MA or commercial plans, do not assume the Original Medicare three-day rule applies; check the actual evidence of coverage.
- Step 4
Appeal the level-of-care decision if the status was wrong
If the patient clinically required inpatient admission, the hospital status decision may be part of the appeal record.
The deadline that applies
Medicare Advantage reconsiderations are generally due within 60 days after the notice (42 CFR 422.582). Employer and ACA plan appeals generally allow at least 180 days. The notice controls.

Related questions
Do observation days count toward Original Medicare's three-day SNF rule?
Generally no. Observation is outpatient status even if the patient stayed overnight.
Do Medicare Advantage plans have to use the three-day rule?
Not always. Many waive it, and the plan's evidence of coverage controls.
Can the hospital change the status after discharge?
Sometimes records can be reviewed, but status changes are difficult. Ask for the admission order and utilization review notes quickly.
