Can my employer verify a telehealth doctor note?

Yes, and this is exactly why the note's provenance matters. Verification is normal practice: an employer (or their HR team) may contact the issuing clinic or telehealth service to confirm that a note is authentic - that it was issued by their clinician, on that date, for you. What the employer cannot do is mine your medical details: the clinician's office can confirm authenticity but generally cannot share your diagnosis or health details with your employer without your permission - the HIPAA privacy rule binds the clinic, even though HHS notes it does not bind the employer asking. Under FMLA, the Department of Labor formalizes this: after giving you a chance to fix any gaps, the employer may contact your health care provider for clarification and authentication of the certification, and if doubts remain they can require a second or third medical opinion at the employer's expense. A telehealth note verifies exactly like an in-person one, because both rest on the same thing - a licensed clinician's name, credentials, and contactable practice. That is also how fake-note sellers get caught: a note with no verifiable clinician behind it fails the one check employers actually run. So the rule of thumb: use a legitimate service with named licensed clinicians, make sure the note shows the practice's contact details, and verification will be boring - which is what you want.
