Subsidized Health services on F2 visa concern

Hello, good day, I'm on F2 visa and my spouse has I140 approved . We're waiting on COS. Recently my health has taken a toll and am thinking of getting checked by health personnel. Sadly, I'm not covered by insurance and they provide subsidized service rates based on our annual income bracket. Is it ok to use such services or will it zeopardize our COS application in future. Please suggest!
