I found 2 stocks-they talked about J-code approval

I found 2 stocks-they talked about J-code approval-not familiar with that term. However, one received their approval on July 24, 2019 and the stock rose 33.7%. Another stock applied on Jan. 7, 2019-has yet to receive approval and the stock has declined 35.7%. Like I said, not familiar with what J-code is, but it was on the CMS (medicare/medicaid) page.
