A member can indeed have the Modern Health benefit via their employer as a primary beneficiary and be a dependent via their partner/spouse's employer. However, we only allow members to have one (1) active Modern Health account out of fairness for other members who might not be a dependent of someone who also has Modern Health as an employer benefit.
That being said, you can only use sessions allotted either by your direct employer, or your partner/spouse's employer. Also, if you are close to maxing out your session allotment or you have exhausted your session allotment, you can reach out to help@modernhealth.com to confirm if your employer offers continued care or what other care methods might be available to you.
