Correct Coding

Correct coding is key to submitting valid claims.

To make sure claims are as accurate as possible, use current valid diagnosis and procedure codes and code them to the highest level of specificity - greatest number of digits - available. The Medicare Claims Processing Manual, Chapter 23, includes information on diagnosis coding and procedure coding and instructions for codes with modifiers.

Evaluation and Management (E/M) codes are a subset of HCPCS Level I codes. Review the Evaluation and Management Services Guide for more information.
