Most people have a misconception of a CS degree as if it teaches you how to code. Computer Science is neither about computers or about science. It's a math and a logic degree. With a CS degree you should be able to code, conjure algorithms and all that jazz out of anything. It teaches you how to be more efficient, write better algorithms, use your hardware to its full potential and etc.
Look at the opportunity cost then make a decision. If I were in your shoes... if I'm making more than $90k AND =<25, then I wouldn't go for a degree. However, education never hurts right?
tl;dr: CS teaches you how to be a better problem solver. You probably know more about "programming" and "languages" than most CS majors.
