How to allow # in \newcommand without \# or another way to defer processing of section of code

I am trying to defer processing of some latex code.

This works,

\documentclass[a4paper,final,11pt]{article}
\usepackage{hyperref}
\begin{document}
here comes a reference
\href{http://www.example.com/doc#list}{doc}
\end{document}

but I need to move up the importing of codeToBeDeferred (containing the \href), and render/process it in the same place. So I changed it to this.

\documentclass[a4paper,final,11pt]{article}
\usepackage{hyperref}
\newcommand{\deferredCode}{
    \href{http://www.example.com/doc#list}{doc}
}
\begin{document}
here comes a reference
\deferredCode
\end{document}

This works, except for the # in the \href, note the # was not a problem in the original code.

side note: I am reading the code early and deferring processing because the code is merged together by a preprocessor, the preprocessor needs to process the deferred code early, but latex needs to do it latter.

Well all this works, except when the codeToBeDeferred has a # in it. \newcommand does not like it. If I put a \ before the # it fixes it, however I do not want to do this: there are a lot of historic versions of this code, I don't want to have to remember when I write new code. The code is valid latex when not part of a \newcommand

How can I allow a # in a \newcommand? or How else can I defer the processing of this block of code?

The # is in a \href in the deferred code, it works outside of a \newcommand.

What I am hoping for, is a wrapper to stop the # being a problem. If the # is only a problem when in a \newcommand then this may be possible.

%somePreambleCode
\newcommand{\deferredCode}{
    \wrapper{
        \href{http://www.example.com/doc#list}{doc}
    }
}
%someOtherCode
\deferredCode

I know that I can escape the # with a \ (changing it to \#), but am hoping for another way.

I don't want to edit the code to be deferred. There is a choice of hundreds of them, I don't want them to be constrained by me doing this deferral trick to fix another problem.
