Read CPT Guidelines
First - your post is in the wrong thread. This thread is for EMPLOYMENT issues/questions.
Please read your CPT guidelines on E/M coding. You'll find the answer clearly stated there. You code ONLY the initial hospital visit, and you use ALL documentation for that DOS to arrive at the level of service. This assumes that all service is done by one provider OR that it is done by partners in the same practice and of the same specialty.
Hope that helps.
