iQIES
iQIES, the Internet Quality Improvement and Evaluation System, is the CMS platform through which home health agencies submit OASIS assessment data and access validation and quality reports. Home health agencies moved to iQIES in January 2020, replacing the legacy QIES and CASPER infrastructure, and the system also supports survey and certification functions used by CMS and state agencies.
What iQIES does for a home health agency
For agency staff, iQIES serves three main functions. First, OASIS submission: assessments are transmitted from the EHR (or uploaded manually) and validated against CMS specifications, with iQIES returning acceptance or errors in a Final Validation Report. Second, reporting: agencies pull the report families that used to live in CASPER, including OASIS submission status, quality measure results, and the provider preview reports that show star ratings and publicly reported measures before they post to Care Compare. Third, survey and certification: surveyors and CMS use iQIES to manage survey activity, and agencies interact with it around certification and related processes.
Getting and managing access
Users authenticate through HARP, the HCQIS Access Roles and Profile system, with individual accounts and multi-factor authentication. Each agency designates a Provider Security Official (PSO) who approves role requests for other staff, and roles are scoped so a biller, QA nurse, and administrator see what their function requires. Two operational rules save headaches: never share accounts, since credentials are individual and shared logins are an access-control violation, and keep at least two people with PSO capability so a single departure does not lock the agency out of its own access administration.
Submission workflow and deadlines
OASIS assessments must be submitted within 30 days of the assessment completion date (item M0090). In practice the flow runs: clinician completes the assessment, QA reviews and the record is locked, the file is exported or transmitted to iQIES, and staff check the Final Validation Report for fatal errors (rejections that require correction and resubmission) and warnings. Late or missing submissions jeopardize compliance with the annual quality reporting requirement, which carries a payment penalty for agencies that fail to meet reporting thresholds. A weekly reconciliation of assessments completed versus assessments accepted in iQIES is the simplest control that catches silent failures.
Reports worth pulling on a schedule
Agencies that use iQIES only as a submission mailbox leave value on the table. Build a monthly reporting habit:
- Final Validation Reports: confirm every transmitted assessment was accepted
- OASIS submission status reports: reconcile against the EHR to find assessments never transmitted
- Quality measure reports: track OASIS-based outcome and process measures ahead of public reporting
- Provider preview reports: review star ratings and measure results during the preview window, when corrections or requests for review are still possible
These reports are the same data CMS uses for Care Compare and HHVBP, so seeing them early is the difference between managing performance and reading about it.
Frequently asked questions
What replaced CASPER reports for home health?
CASPER reporting functions for home health moved into iQIES when agencies transitioned in January 2020. The equivalent reports, including validation, submission status, quality measures, and provider previews, are now generated inside iQIES.
What happens if an OASIS is submitted late to iQIES?
Assessments are due within 30 days of the M0090 completion date. Late submissions can still be accepted, but chronic lateness or missing assessments put the agency at risk on the quality reporting requirement, which carries a payment reduction for non-compliant agencies, and they undermine the accuracy of quality measures and star ratings.
How does an agency get iQIES access for a new employee?
The employee creates an individual HARP account, completes identity proofing, and requests the appropriate iQIES role for the agency. The agency's Provider Security Official approves the request. Access should be removed promptly when staff leave, since accounts are individual and auditable.
