CDY is DYS724, but it and 3 others aren't tested by DNAHeritage.
Not having all 43 markers is a major disadvantage when using the SMGF database. It seems to be the most useful for genealogists, because of the pedigrees and extended haplotypes.
FTDNA doesn't test 11 of the DNAH markers in its standard panels. However, it does test some, or all, at its new lab, which offers individual marker testing. The product page is available to current customers only, so I don't know which markers they are offering or the prices.
Other options for these 11 require submission of another sample, but it is not a bad idea to have results double-checked. Although errors are found only occasionally, they can be time-consuming and cause a lot of discord when they erroneously contradict a documented genealogy. Some options are:
(1)Submit a sample to www.smgf.org for a free test. However, it takes about a year for the results to be posted to the database and the results have to be extracted from the database by trial and error, since they don't report them directly.
(2) Relative Genetics has a special conversion rate for someone who has had 25 or more markers tested elsewhere. See:

It is a little more expensive than buying just the 11 markers from FTDNA. However, they do run all 43 markers, so it will check on initial results.
(Relative Genetics and DNAHeritage routinely test two different samples, so there isn't much advantage to having their results checked at another lab.)
