**NOTE- TERMS IN BRACKETS HAVE BEEN EDITED TO PROTECT CONFIDENTIALITY** Based on record review, review of the RAI (Resident Assessment Instrument) Version 3.0 Manual and staff interviews, the facility failed to transmit Minimum Data Set (MDS) Assessments timely for three residents (R) (#1, #2, and #3) of 29 sampled residents. Findings include: Review of the RAI Version 3.0 Manual dated October 2015 documented under Chapter 5: Submission and Correction of the MDS Assessments, Transmitting Data - Assessment Transmission: comprehensive assessments must be transmitted electronically within 14 days of the Care Plan Completion Date. All other MDS assessments must be submitted within 14 days of the MDS Completion date. R#1 was admitted on [DATE] with diagnosis of: (not an all-inclusive list) heart failure, hypertension, wound infection, arthritis, and hyponatremia. The discharge MDS for this resident had an Assessment Reference Date (ARD) of 3/18/19. This discharge MDS was not transmitted until 8/28/19 making this assessment 138 days overdue. R#2 was admitted on [DATE] with diagnosis of: (not an all-inclusive list) hypertension, gastro esophageal reflux disease, thyroid disorder, hip fracture and anxiety disorder. The ARD for the discharge MDS for this was 3/31/19. This discharge MDS was not transmitted until 8/28/19 making this assessment 132 days overdue.

This annual MDS was not transmitted until 8/28/19 making this assessment one day overdue. During an interview on 8/28/19 at 1:23 P.M., MDS Coordinator AA stated that R#1 and R#2's MDS assessments were not completed therefore did not go into her batch list to be transmitted. She also stated that R#3's MDS was transmitted late by one day. She stated that she transmits MDS's once or twice per week and then runs a validation report to compare those assessments transmitted to her schedule of MDS's due to ensure they were all accepted. She indicated these MDS assessments fell between the cracks. During an interview with the Director of Nursing (DON) on 8/29/19 at 9:00 a.m., she stated that she expects for the MDS staff to complete the MDS assessments by the transmission due date indicated per the system and the RAI Manual.
