A big thank-you to Walter Nickeson for providing the solution to my problem!
I also received interesting, useful responses from Terry Reese and Bryan

I think this might work:
Find:
(=852.*\$h)([A-Z]){1,3}([0-9\.]*\$i)([A-Z].*)
Replace with:
$1$2$3.$4
The expression looks for a subfield $h that begins with a string of one
to three capital letters that is followed by only digits or decimals
(i.e., a classification number without a Cutter), in turn followed by a
subfield $i that begins with a capital letter instead of a decimal. The
replacement expression returns the whole field with the decimal added
after the second subfield code.
