Attention: OASIS (HHA) to QIES Assessment Submission and Processing (ASAP) System (posted 11/21/2014)

Effective January 1, 2015, OASIS assessment data will be submitted to CMS via the national OASIS Assessment Submission and Processing (ASAP) system.

With the implementation of the OASIS ASAP system, Home Health Agencies will no longer submit OASIS assessment data to CMS via their state databases. To access the OASIS ASAP system, you will need a QIES / HHA User ID.
If you currently have a QIES / HHA User ID no action is required. This User ID will allow access to both the OASIS (ASAP) Submission System and CASPER Reporting System.

If you do not have a QIES / HHA User ID, refer to the OASIS Access Information page for details regarding how to obtain access.

In order to transition data from the state databases to ASAP, the OASIS submission system will shut down at 6:00 p.m. ET on December 26, 2014. The OASIS ASAP system will be available at 12:00 a.m. ET on January 1, 2015.
Files submitted on or after January 1, 2015 must follow version 2.10 (which supports OASIS-C) and version 2.11 (which supports OASIS-C1) of the OASIS data submission specifications.
