No, LCB staff is hard at work codifing acts passed by the 2013 Legislature. We do not expect to receive the 2013 Nevada Revised Statutes until November or December. Supplements to Lexis' Michie's Nevada Revised Statutes Annotated and West's Nevada Revised Statutes Annotated should be available shortly thereafter.
In the meantime, update the 2011 NRS Reprint using the tables and indices available on the LCB's 2013 Bill Information page.
If you prefer print, you can use the tables in the 2013 Statutes of Nevada advance sheets (REF KFN625 .A2 2013 and READY REF KFN625 .A2 2013). The bound 2013 Statutes of Nevada has not yet been published, and will be added to the collection as soon as it is available.
A word of caution: don't think you can avoid updating by using Westlaw and Lexis. Currently the NRS available on Lexis and Westlaw is the 2011 version, though there should be red Shepard's and KeyCite flags for those sections which have been amended. Titles and chapters, however, are trickier and it is good practice to review the tables linked above.
Oh, and when you are done with the 2013 session, you can do it again with the tables for the 27th Special Session.
tl;dr: no, use these tables to update the 2011 NRS.
