Are income limitations monthly or yearly?

I'm in Louisiana. When I originally received Medicaid I was told that there was a monthly income limitation of $1,667. I've tried to look online and call to verify that this is still the case, but am finding it hard to talk to an actual person. Are most Medicaid income limitations monthly or yearly? I'm interested in a job opportunity that would put me $130 over the above stated monthly limit only during the months that have 5 weeks. Would I risk losing Medicaid within this scenario?
