Skilled Nursing Facility 3-Day Rule Billing

To qualify for Skilled Nursing Facility (SNF) extended care services coverage, Medicare patients must meet the 3-day rule before SNF admission. 

The 3-day rule requires,

  • Three-day-consecutive inpatient hospital stay. 
  • Three-day-consecutive stay counts inpatient setting.
  • Starting with the calendar day of hospital admission.
  • Doesn’t include the day of discharge or any pre-admission time spent in the ER or outpatient observation.

SNF extended care services are an extension of care a patient needs after a hospital discharge or within 30 days of their hospital stay (unless admitting them within 30 days is medically inappropriate).

Example

A 68-year-old male patient went to the hospital ER after falling on May 17th from his home and a physician admitted him to the hospital on the same day. On subsequently May 20, the hospital discharged him to SNF extended care services. 

For this case, the patient did qualify the 3-day rule. Hospitals can count the admission day (May 17th to May19th), but not the discharge day (May 20). 

Tips

Medicare considered inpatients meet the 3-day rule by staying 3 consecutive days in 1 or more hospital(s) as well.

Additional Information About Modifiers

Sequencing of modifiers  How can that be if the modifiers used were accurate?  There is an order to reporting modifiers and there are three categories that modifier usage fall under:  1. Pricing  Pricing modifiers are always sequenced “before” payment modifiers and/or location modifiers.   The only exception to this rule is when a global surgery package is involved.  For example, you would code modifier 58 first and modifier 82 second in a global surgery.  A few examples of pricing modifiers are: 22, 26, 50, 52, 53, 62, 80, and P1-P6.   2. Payment   Payment modifiers alert the insurance carrier that there is a special situation within the claim  Some examples of payment modifiers would be: 24, 25, 51, 57, 58, 59, 76, and 78.  3. Location  Examples of location modifiers are: E1-E4, FA, F1-F9, LC, LD, LT, RT, RC, TA, and T1-T9.  The general order of sequencing modifiers is ( 1) pricing (2) payment (3) location. Location modifiers, in all coding situations, are coded “last”.  If you code
