\documentclass{article}
\usepackage{makeidx}
\makeindex
\usepackage{hyperref}
\newcounter{idx}
\newcommand*{\IndexHeading}[1]{%
  \renewcommand*{\theidx}{#1}% counter appearance
  \renewcommand*{\theHidx}{idx.#1}% link name
  \refstepcounter{idx}%
  \label{idx:#1}%
  \textbf{\Large #1}%
}

\begin{document}
\section{Hello World}
\index{Hello}
\index{World}
Index: \ref{idx:H}, \ref{idx:W}
\newpage
\printindex
\end{document}

If the index is in a separate file, the link can be done either by
the help of package xr or with the link names:
  \href{index.pdf#idx.H}{\textbf{H}}
