M0100 — Reason for Assessment

Load sample:

Use synthetic test data only. Use ^ for blank/NA values per CMS file convention. SSNs CMS already rejects (e.g. 123456789) are safe to paste.

M0064 — SSN

9 digits or ^ for blank

M0066 — Birth date

YYYYMMDD, YYYYMM, or YYYY

M0030 — SOC date

M0032 — ROC date

M0032-NA flag

M0090 — Info completed date

M0102 — Physician ordered SOC/ROC date

M0102-NA flag

M0104 — Physician referral date

M0906 — Discharge/transfer/death date

M1005 — Inpatient discharge date

M1005 unknown flag

M1021 — Primary diagnosis ICD-10

Educational only — passing this validator does NOT guarantee iQIES will accept your submission

This tool checks 18 of approximately 271 currently active fatal edits in the OASIS-E2 V3.02.0 specification. It does not check skip patterns beyond the listed edits, quality-measure (QM) edits, branch/CCN/NPI registry validity, vendor-authorization edits, or inter-record consistency. The CMS HH PPS Final Validation Report from your OASIS submission software is the only authoritative source for whether iQIES will accept a record.

Source: OASIS-E2 Data Submission Specifications V3.02.0 (effective 2026-04-01); QTSO Error Message Reference Guide v2.4 (posted 2026-02-05). Last reconciled with CMS source: 2026-04-28. This validator may lag the current iQIES production environment by up to 30 days.
