Reasons a health insurance application may be denied? Kaiser

My husband lost his job and they are not offering Cobra. We have our Kaiser health insurance through them but it will be terminated at the end of the month. I am schedule to have a c section next month.

Basically I need coverage. I have applied to medi-cal but they are telling me it can take 45 days and then to get it set up with Kaiser is a whole separate process. Baby will be here sooner than that. So I applied for an individual plan direct through Kaiser since it happened to be open enrollment. Definitely more expensive but I don’t care.. I just need my Kaiser coverage to continue into January. They said I can cancel anytime so I’m hoping to just use this for the gap until medi-cal can be approved in February.

My question is what are the chances of denying my application? Like what are common reasons an application might get denied? They said processing time is 7-10 business days and I submitted the application on the 15th so he’s cutting it close and I just want confirmation already that my coverage will continue and the c section will go as planned.
