     • Three errata issues (A53, A54, and A55) were identified after V2.11.3 of the OASIS-C1/ICD-9 data specifications was put into production.  These three issues have not been implemented in V2.11.3 of the data specifications.  Users of the data specs must treat the resolutions of these three issues as part of the V2.10 and V2.11 data submission specifications.
     • No further updates are planned for V2.10 of the OASIS-C data specs; V2.10.1 is therefore the last release planned for OASIS-C. The issue resolutions listed in Sections A and B of the Errata document have not been implemented in V2.10.1 of the data specifications. Users of the OASIS-C data specs must treat the resolutions of all of the issues listed in Sections A and B as part of the V2.10 data submission specifications.
