It would depend on the context of how the DNA sequencing was provided.
If your Doctor ordered it as part of a treatment plan and billed your health insurance, then yes, it's a medical record covered by HIPAA.
If you personally ordered DNA sequencing and gave the results to GEDmatch, then HIPAA does not apply. GEDmatch is neither a Covered Entity[1] nor Business Associate[2] of a Covered Entity. From a legal perspective the DNA database at GEDmatch is no different than phone or banking records.

I can't find any reference to HIPAA in 23andme's privacy policy and I don't believe they are currently considered a covered entity. I don't even know if their data is considered medical information in the same way a diagnosis would be.
HIPAA only applies to "covered entities" and their business partners, which are (1) health plans, (2) health care clearinghouses, and (3) health care providers who electronically transmit any health information in connection with transactions for which HHS has adopted standards. GEDmatch is none of those.
