Once deployed, then the original code is final.
Further upgrading of a smart contract becomes difficult as it would require that you've taken upgradeability patterns into consideration during your early contract architecting stage (e.g. you could use proxy contracts, libraries, or registry contracts to separate certain concerns from each other to allow for upgradeability mechanisms).
