Eli's Rehab Report

When the Centers for Medicare & Medicaid Services (CMS) added the new MDS 3.0 item O0420 — Distinct Calendar Days of Therapy, you didn’t simply get an additional item to code in the MDS. In fact, the addition of O0420 has further and far-reaching implications for calculating classification into the Medicare Rehabilitation Medium and Low RUG-IV categories.

 

Simply stated, item O0420 requires that you report the distinct calendar days of therapy provided. “Distinct calendar days represents the different days therapy was provided in the assessment reference date (ARD) or change of therapy (COT) review look-back period,” wrote Kris Mastrangelo in a recent Harmony Healthcare International blog posting. “In other words, how many different days were rehabilitation services provided for greater than 15 minutes over the last seven days?”

 

Mastrangelo provided the following example:

 

How to code: You would report this as:

How Distinct Calendar Days Impacts Your RUG Classification

 

Old way: Before Oct. 1, 2013, the MDS RUG-IV Grouper allowed you to meet the classification criteria for the Medium Rehabilitation category without five distinct days of therapy, Mastrangelo noted.

New way: But now “the RUG-IV grouper will only calculate a Rehabilitation Medium RUG category when 150 minutes of therapy is provided across five distinct calendar days,” Mastrangelo said. This means that within the seven-day observation period of the MDS or COT review, therapists must deliver services to the patient on at least five of the seven days in the observation period from the ARD.

 

“If this criterion is not met, regardless of the number of minutes or total of combined discipline visits of rehabilitation services provided, the RUG score generated will reduce to a Nursing RUG,” Mastrangelo warned. Here’s the example:

 

How to code: For this example, Mastrangelo instructed that you would code as follows:

“Although therapy was provided for a total of 10 visits, the Rehabilitation Medium criteria will not be met and a Nursing RUG classification will apply,” Mastrangelo noted. This would fall into the Rehabilitation Low categories, for which therapy must be provided on three or more distinct calendar days — only if there were two nursing restorative programs on at least six days during the look-back period.

 

Here is another example from a blog posting by Gina Tomcsik, director of compliance for Functional Pathways in Knoxville, TN:

 

How to code: Prior to Oct. 1, 2013, this example would produce a Medium Rehabilitation RUG, counting as five days of therapy, Tomcsik explained. But under the new rules, the RUG would classify as Low Rehabilitation with four distinct days of therapy (again, with two nursing restorative programs on at least six days):

Keep in mind: The criteria for Ultra High, Very High, and High categories won’t change under the 2014 requirements, according to Mastrangelo. For RUG classification in these categories, at least one discipline must provide five days in the observation period in addition to meeting the criteria for total minutes.
