Skilled Nursing Facilities

Skilled nursing facility (SNF) and swing bed (SB) providers must submit either a qualifying hospital stay or an appropriate condition code for bypassing the qualifying stay, if applicable, on all claims including initial and subsequent claims that are submitted as covered. This is applicable for submitted bill types 21x (SNF inpatient) and 18x (SB inpatient). This also includes all covered claims (i.e., claims submitted for benefits exhaust denials). Covered claims submitted on 21x and 18x bill types that do not contain a qualifying hospital stay (using occurrence span code 70 with the qualifying hospital stay dates) or an appropriate condition code indicating why a qualifying hospital stay is not applicable will be denied.

If a patient elects hospice, a hospice notice of election (NOE) is considered timely filed when submitted to and accepted by the Medicare contractor within five calendar days after the hospice election. (The NOE also must not be returned to the provider for correction.)

Example: The date of hospice election is October 1. A timely filed NOE would be submitted and accepted by the Medicare contractor on or before October 6.

In instances where the NOE isn't timely filed, the provider is liable for the days of hospice care from the hospice admission date to the date the NOE is submitted to, and accepted by, the Medicare contractor. The provider must not bill the beneficiary for this untimely period.

Example: The date of hospice election is October 1. The NOE wasn't submitted and accepted by the Medicare contractor until October 10. Provider-liable days would be October 1–9.

While a hospice can’t “revoke” a patient’s election, an individual or patient representative may revoke the election of hospice care at any time in writing. The document must include:

• A signed statement that the individual revokes the election for Medicare coverage of hospice care for the remainder of that election period
• The effective date of that revocation
• A designated effective date earlier than the date that the revocation is made

The individual forfeits hospice coverage for any remaining days in that election period. An oral revocation of benefits isn’t acceptable.

Upon the revocation of Medicare-covered hospice care for a particular election period, the individual resumes the Medicare benefits coverage waived when hospice care was elected. An individual may, at any time, elect to receive hospice coverage for any other hospice election period that he/she is eligible to receive.

CMS billing guidance during an inpatient stay is:

• When hospice is elected:
  • Bill traditional Medicare for period before hospice election
  • Patient status code is 51 (discharge to hospice medical facility)
  • Discharge date is the effective date of hospice election
  • Bill hospice for period of care after hospice election
• When hospice is revoked:
  • Bill hospice for period up to hospice revocation
  • Bill traditional Medicare for period after hospice revocation
  • Admission date is same as the hospice revocation date
  • Statement 'from' date is the same as the hospice revocation date
