Medicare Denied Claim: Wrong Level of Care

What This Means

Medicare reviewed your claim and determined that you did not meet the medical criteria for the level of care that was billed. This most commonly happens in two situations:

• Hospital stays: Your hospital stay was reclassified from inpatient to observation (outpatient) status, meaning Medicare Part A will not cover the stay.
• Skilled nursing facilities (SNFs): Medicare determined that you did not need the level of skilled care provided, or you did not meet the 3-day inpatient hospital stay requirement.

This denial can have a major financial impact, especially if it affects your eligibility for follow-up SNF care.

Why This Happens

• Your hospital stay was reclassified. Hospitals sometimes change a patient’s status from inpatient to observation after the fact, based on clinical criteria or utilization review. This can happen during your stay or even after discharge.
• You did not meet the 3-day inpatient requirement for SNF coverage. Medicare Part A only covers SNF care if you had at least 3 consecutive inpatient days (not counting the discharge day). Observation days do not count, so some patients who spent several days in the hospital still do not qualify.
• Medicare determined a lower level of care was appropriate. For some conditions, Medicare may decide that outpatient treatment or home care would have been sufficient instead of a hospital or SNF stay.
• The documentation did not support the level of care. Even when the clinical situation clearly called for a higher level of care, the medical records submitted may not have conveyed the severity of your condition.

Should You Appeal?

What To Do Next

1. Determine the specific reason for the denial. Read your denial notice carefully. Was the issue your hospital status (inpatient vs. observation), your eligibility for SNF coverage, or the medical necessity of the level of care itself?
2. If your hospital status was changed, exercise your new appeal rights. As of February 2025, you can file an expedited appeal while still in the hospital if your status is changed from inpatient to observation. If you have already been discharged, you can still file a standard appeal. For past stays dating back to January 1, 2009, a retroactive appeal process is available through January 2, 2026.
3. Ask your doctor for supporting documentation. Your doctor can write a letter explaining why the higher level of care was medically necessary for your condition. This is the most important part of your appeal.
4. Check whether you received a MOON notice. If you were in observation for more than 24 hours, the hospital was required to give you a Medicare Outpatient Observation Notice. This notice is important documentation for your appeal.
5. Contact your State Health Insurance Assistance Program (SHIP). SHIP counselors provide free help to Medicare beneficiaries and can guide you through the appeal process, especially for complicated level-of-care situations.
