Insurance Denied Skilled Nursing Facility or Nursing Home? Here's How to Appeal

Skilled nursing facility (SNF) and nursing home denials often strike at the most vulnerable moment — when a patient has just been discharged from the hospital and needs post-acute care to recover safely. Understanding Medicare's rules, federal court precedent, and your expedited appeal rights can mean the difference between receiving needed care and being sent home without adequate support.

Why Insurers Deny SNF and Nursing Home Claims

• Three-day hospital rule not met: Medicare requires a 3-consecutive-day qualifying inpatient hospital stay before covering SNF care — and observation status days do not count
• Improvement standard incorrectly applied: The insurer argues the patient is not improving and therefore does not qualify for continued SNF coverage, ignoring the Jimmo maintenance standard
• "Not skilled" care: The insurer argues the care needed is custodial rather than skilled nursing or therapy
• Coverage exhausted: Medicare Part A covers SNF up to 100 days per benefit period; commercial plan limits vary
• Premature discharge: The SNF or insurer initiates discharge without proper clinical justification

Common denial codes: CO-50 (not medically necessary), CO-96 (non-covered charge), CO-119 (benefit maximum reached).

How to Appeal an SNF or Nursing Home Denial

Step 1: Determine the Basis of Denial

Identify whether the denial is for the 3-day qualifying stay, observation status classification, medical necessity of SNF level of care, the improvement standard, or exhaustion of benefit days. Each ground requires a distinct response.

Step 2: Challenge Observation Status Under the NOTICE Act

The NOTICE Act (2016) requires hospitals to notify Medicare patients in writing (via the Medicare Outpatient Observation Notice, or MOON) if placed under observation status for more than 24 hours. If you were not notified, cite this regulatory violation. Request that the hospital's utilization review committee reclassify your stay from observation to inpatient if clinical criteria for inpatient admission were met.

Step 3: Invoke Jimmo v. Sebelius for Maintenance Care

The Jimmo v. Sebelius settlement (2013) and subsequent court orders (2017) established that Medicare covers skilled nursing and therapy services even when the patient is not improving — as long as skilled care is necessary to maintain the patient's current condition or prevent deterioration. This is codified in the Medicare Benefit Policy Manual, Chapter 8. If the denial cites lack of improvement or a plateau in recovery, cite Jimmo and the CMS manual update directly. A patient managing complex wounds, receiving IV medications, or requiring unstable condition monitoring is covered regardless of rehabilitation progress.

Step 4: Document Skilled Care Requirements

For Medicare SNF coverage, the patient must need skilled nursing care (IV therapy, wound care, complex medication management) or skilled rehabilitation (PT, OT, or SLP requiring a licensed therapist) on a daily basis — at minimum 5 days per week. Have the SNF nurses and therapists document specific skilled care tasks in detail, not vague descriptions.

Step 5: File an Expedited BFCC-QIO Appeal for Imminent Discharge

If a Medicare SNF is discharging you prematurely, request an expedited appeal through your Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) before or on the day of the planned discharge. The BFCC-QIO must decide within 1 business day of receiving medical records. If you request the appeal before the effective discharge date, you are not liable for costs incurred during the QIO review period — even if the QIO ultimately upholds the discharge.

Step 6: File a Standard Medicare Redetermination

For non-urgent SNF denials, file a Medicare Redetermination (Level 1 appeal) within 120 days of the initial denial. If denied, proceed to QIC reconsideration (Level 2) and then ALJ hearing (Level 3) if necessary.

What to Include in Your Appeal

• BFCC-QIO expedited appeal request with documentation of skilled care needs and why discharge is premature
• Jimmo v. Sebelius citation and CMS Medicare Benefit Policy Manual, Chapter 8 if improvement standard was incorrectly applied
• NOTICE Act citation and evidence of observation status misclassification if the 3-day rule is at issue
• SNF physician or medical director letter documenting specific skilled care needs (nursing, PT, OT, or SLP) and why home care is insufficient
• Hospital admission records distinguishing inpatient from observation status days
