Observation Status at a New Hampshire Hospital

The Billing Classification That Changes Everything

Your parent can spend three nights in a hospital bed, receive IV medications, undergo diagnostic tests, and be monitored by nursing staff around the clock — and still not be classified as an inpatient. Observation status is a billing designation that treats the entire hospital stay as outpatient care, even when the experience looks and feels exactly like an admission.

This distinction has real financial consequences. Medicare Part A covers skilled nursing facility care only after a qualifying three-day inpatient hospital stay. Time spent under observation status does not count toward that three-day requirement. A parent who spends 72 hours in the hospital under observation and then needs rehabilitation at a skilled nursing facility may have to pay the full private-pay cost — averaging $11,000 to $12,000 per month in New Hampshire — unless another payer, such as Medicare Advantage or Medicaid, covers the stay, because Original Medicare Part A will not cover the SNF stay without a qualifying inpatient stay.

Observation status also shifts medication costs. Under inpatient admission, Medicare Part A covers drugs administered during the stay. Under observation, those same drugs may be billed under Part B with its 20% coinsurance, and some medications may not be covered at all.

The MOON Notice

Hospitals are federally required to deliver the Medicare Outpatient Observation Notice (MOON, Form CMS-10611) to a Medicare patient who has been receiving observation services for more than 24 hours. The notice must be delivered no later than 36 hours after observation begins or before discharge, whichever comes first.

The MOON tells the patient three things: that they are under observation status, that they are not formally admitted as an inpatient, and that this classification affects their financial responsibility for the stay and any subsequent post-acute care.

The MOON is informational — signing it acknowledges receipt, not agreement. If you receive this notice, it's your signal to act immediately on getting the status reconsidered.

How to Push for Inpatient Conversion

The attending physician and the hospital's utilization review committee make the inpatient-versus-observation decision based on clinical criteria, primarily CMS's "two-midnight" benchmark. If the physician expects the patient will need hospital-level care spanning at least two midnights, the stay should qualify for inpatient admission.

Here's what families can do:

Talk to the attending physician, not just the case manager. Ask directly whether your parent's clinical condition meets the two-midnight benchmark. If the physician believes it does but the hospital's utilization review has classified the stay as observation, ask the physician to document the clinical rationale for inpatient admission and formally request a status change.

Document functional decline and medical instability. The stronger the record of clinical need — vital sign instability, new diagnoses, medication adjustments, fall risk — the stronger the case for inpatient classification.

Ask about self-administered drug exclusions. If your parent is taking medications during the observation stay that would normally be self-administered at home, they may face unexpected charges. Knowing which medications are at risk helps you prepare financially.

If the hospital refuses to convert the status, you retain the right to appeal through Medicare after discharge. You can also file a complaint with Acentra Health, New Hampshire's BFCC-QIO, at 1-888-319-8452 regarding the classification decision.

Planning Around Observation Status

When observation status appears locked in and your parent will need post-acute rehab, the financial math changes significantly. Without a qualifying three-day inpatient stay, Medicare Part A won't cover the SNF. Families at this point need to evaluate whether the Choices for Independence (CFI) Medicaid waiver — New Hampshire's primary home and community-based care pathway — or private-pay rehab is the more viable option.

The New Hampshire Hospital Discharge Guide includes a tracking worksheet to calculate qualifying inpatient hours and a decision tree for navigating the financial fallout when observation status blocks the standard Medicare SNF benefit.
