I work in a 3 location practice, with 20+ MD's plus many APP support staff. We have in-office coding and billing. The certified coders work with the E/M's, HCC's, questions, education, and auditing. The billers/AR team deal with getting the claims out cleanly and any denials. They ask the coders for their expertise as needed. My question is: How do similar size practices divide up the tasks between the Coders and billers/AR in comparison? Are they kept as two separate entities or do you combine the two and if so, how? Also are they all in-house staff? Thank you for any insight you can provide.
