This blog post describes the mapping specifications and the conversion between HIPAA 837 professional and CMS 1500 in PDF format.
This was another one of the 300+ pre-defined HIPAA maps that we have developed in the past. The user can integrate this map into their system with no further work. You can test the map by going to Redix HIPAA Compliance and Conversion Demo.
A blank CMS 1500 form looks like the following. 
Mapping Specification
The CMS 1500 form is using the box id to identify the meaning of each field. For example, a patient name is in box 2 and the patient address is in 5. The patient name in a HIPAA 837 professional is defined in 2010BA. Below is a table to describe the box id in the CMS 1500 form and its corresponding element in HIPAA 837 professional.
