---------

full paragraph from the instructions document of form I-485:

 

You are NOT required to submit Form I-693 at the time you file your adjustment application, but may do so if you
wish. Because of the time-limited validity of Form I-693, you may choose to submit your Form I-693 after you file
your Form I-485. You may also submit Form I-693 in person at an interview in a USCIS field office, if an interview is
required. By waiting to submit Form I-693, you may avoid having to repeat the immigration medical examination.

If you are adjusting from a K1, the medical exam conducted for the visa interview should have followed your file.
