My inpatient hospital stay was denied under the two-midnight rule. What can I do?
The two-midnight benchmark asks whether the admitting physician reasonably expected hospital care crossing two midnights, or whether inpatient admission was otherwise medically necessary due to risk. Appeal with the admission order, physician expectation, severity of illness, services provided, and why observation status was not appropriate.
What to do, in order
- Step 1
Get the admission order and utilization review notes
The exact order time, physician expectation, and hospital review notes matter.
- Step 2
Show risk at the time of admission
Appeals turn on what was known when admitted: symptoms, instability, tests, treatment intensity, and risk of adverse event.
- Step 3
Address the two-midnight benchmark directly
Explain whether the physician expected two midnights or why inpatient admission was justified despite a shorter stay.
- Step 4
Ask for the policy and reviewer credentials
The plan should disclose the medical policy and qualifications of the reviewer who denied the inpatient level.
The deadline that applies
Employer and ACA plans generally provide at least 180 days to appeal. Medicare Advantage denials generally use the 60-day reconsideration clock in 42 CFR 422.582. The notice controls.

Related questions
Does a stay under two midnights always have to be observation?
No. The rule is a benchmark, and inpatient admission can still be appropriate in cases with serious risk or intensive services.
Who can write the strongest letter?
The admitting physician or hospitalist, because the appeal needs the expectation and risk at admission.
Can the hospital appeal separately?
Yes, and you can still file a member appeal. Ask the hospital to share its appeal record.
