CMS updates Medicare COT assessment requirements.
The COT unscheduled PPS Other Medicare Required Assessments (OMRAs) are mandatory. They are required when a Medicare Part A resident receiving rehabilitation therapy qualifies for an Ultra High, Very High, High, Medium or Low Rehabilitation Resource Utilization Group (RUG) and when the intensity of therapy service changes to the point that the current payment category (RUG) is no longer applicable. (1)
The COT has a "rolling" assessment reference date (ARD) window, with an ARD checkpoint every seven days. It is calculated from the ARD of the most recent PPS assessment used for payment, with the exception of an End of Therapy with Resumption (EOT-R) assessment. The rolling window is required as long as the resident qualifies for a therapy RUG, regardless of whether the therapy RUG is the paying RUG, as in situations where a non-therapy RUG pays at a higher rate due to case-mix index maximization. In circumstances where facility staff are completing an EOT-R, the COT rolling window is counted from the date of the therapy resumption, after a break in therapy of at least three days and with the treatment resuming within five days of the last therapy treatment date.
The sole purpose of the COT assessment rolling windows is to monitor the level of therapy services provided and to adjust the billable RUG as frequently as weekly so that the Medicare Part A claim accurately reflects the current services. Monitoring the reimbursable therapy minutes (RTMs) in order to detect payment level changes can be a monumental task for facility staff, especially if they are not clear on the requirements.
To determine whether a COT is needed, facility staff must track RTMs daily. RTMs include total therapy minutes provided, number of therapy days and number of disciplines providing therapy. Therapy minutes include all individual minutes, half of concurrent minutes, and one-fourth of group minutes per each therapy discipline (physical therapy, occupational therapy and speech therapy). RTMs do not include items such as initial therapy evaluations and documentation time. If changes in therapy service impact the payment RUG, then a COT is required. Facility staff should begin tracking RTMs from the ARD of the most recent PPS assessment, or from the therapy resumption date (indicated in MDS item 00450) if an EOT-R assessment was completed.
Since most Medicare therapy RUG groups require at least five days of therapy, a resident who misses enough therapy in a seven-day period will not qualify for a therapy RUG. To ensure accuracy of the therapy RUGs based on days of service, in 2013, CMS implemented a new coding item on the MDS (00420), titled Distinct Calendar Days of Therapy. While this new item established a clear threshold that matched the requirements for Medicare Part A rehabilitation, it had an adverse impact on residents who were at the facility solely for therapy.
If a resident missed enough therapy (three out of seven days), and the missed days were not sequential, he or she would not qualify for a therapy RUG or an EOT-R. In all likelihood, the qualifying RUG would be one of the lowest paying, and the facility would have no recourse for rectifying the situation until the next scheduled assessment was completed. When the COT window count stopped, the facility would get a reduced payment until the next scheduled PPS assessment, which could be as far as 30 days away. This could result in the facility's losing hundreds of dollars a day in Medicare payment and thousands of dollars during the 30 days between scheduled assessments' standard billing cycles.
Before the COT assessment process was established, facilities were more likely to get paid for a higher level of therapy than was actually provided. After the 2013 COT policy change, facilities were at risk of being underpaid for the services they were providing.
To correct this payment discrepancy, CMS implemented a welcome solution. They clarified that, effective October 1, 2014, a COT OMRA can be completed only when a resident is currently classified into a RUG-IV therapy group (regardless of whether the resident is classified into that group for payment), based on the resident's most recent assessment used for payment. (1) When a resident no longer qualifies for a therapy RUG, the COT rolling windows stop. However, when a resident is no longer classified into a RUG-IV therapy group, a COT can be completed when the following two conditions are met:
1. Resident has been classified into a RUG-IV therapy group on a prior assessment during the resident's current Medicare Part A stay, and
2. No discontinuation of therapy services (planned or unplanned discontinuation of all rehabilitation therapies for three or more consecutive days) occurred between Day 1 of the COT observation period for the COT OMRA that classified the resident into his/her current non-therapy RUG-IV group and the ARD of the COT OMRA that reclassified the resident into a RUG-IV therapy group. (1)
Under these circumstances, completing the COT OMRA is optional, meaning that completing the COT to get a resident back into a therapy RUG is not required. One important nuance to the above criteria is that facility staff may only complete a COT to reclassify a resident into a therapy RUG group when the previous assessment in which the resident dropped out of therapy RUGs was a COT or COT combined with another type of assessment.
To illustrate the COT requirements, CMS provides the following example: (1)
Mr. T classified into the RUG group RUA on his 30-day assessment with an ARD set for Day 30 of his stay. On Day 37, the facility checked the amount therapy provided to Mr. T. and found that while he did receive the requisite number of therapy minutes to qualify for this RUG category, he only received therapy on 4 distinct calendar days, which would make it impossible for him to qualify for an Ultra-High Rehabilitation RUG group. Moreover, due to lack of 5 distinct calendar days of therapy and a lack of restorative nursing services, Mr. T. did not qualified for a therapy RUG group. The facility completes a COT OMRA for Mr. T, with an ARD set for Day 37, on which he qualifies for LB1. Mr. T's rehabilitation regimen continues from that point, without any discontinuation of therapy or three consecutive days of missed therapy. On Day 44, the facility checks the amount of therapy provided to Mr. T during the previous 7 days and finds that Mr. T again qualifies for the RUG-IV therapy group RUA.
In this example, note that on day 37 the resident did not qualify for a therapy RUG group (LB1); however, because the assessment resulting in the non-therapy RUG level was a COT, the facility staff were allowed to complete another COT to qualify the resident back into a therapy group. A key consideration for facility staff in this situation is whether the previous assessment was a COT or a COT combined with another allowable assessment type such as a regularly scheduled assessment (14-day, 30-day, 60-day, or 90-day).
Because the COT requirements are complex, it takes teamwork between nursing and therapy services to manage them effectively. Don't rely on one person in the facility to manage the process alone. Be sure to implement a check-and-balance system to monitor RUGs and to track therapy service minutes and days of treatment. With the right effort, financial pitfalls of COT mismanagement can be avoided.
