What CMS's data specification says about -5800
CMS's OASIS-E2 Data Submission Specifications V3.02.0 (HTML edit page oe_5800.html, generated 11/05/2025) list edit -5800 with edit type Consistency and severity Fatal. The edit text, as CMS publishes it:
The following rules refer to the "BIMS component items" which are C0200, C0300A, C0300B, C0300C, C0400A, C0400B and C0400C: (a) If all of the BIMS component items are active and have numeric values (not dash) and if three or fewer of the BIMS component items are equal to [0], then C0500 must equal the sum of the values of the component items. (b) If all of the BIMS component items are active and have numeric values (not dash) and if four or more of the BIMS component items are equal to [0] then C0500 must equal the sum of the values of the component items OR it must equal [99]. (c) If some, but not all, of the BIMS component items have a value of [-], then C0500 must equal [99]. (d) If all of the BIMS component items have a value of [-], then C0500 must equal [-].
