While diagnosis coding to the correct level of specificity is the goal for all claims, for 12 months after ICD-10 implementation, Medicare review contractors did not deny physician or other practitioner claims billed under the Part B physician fee schedule through either automated medical review or complex medical record review based solely on the specificity of the ICD-10 diagnosis code as long as the physician/practitioner used a valid code from the right family.

Beginning on October 1, 2016, the one-year contingency period during which clinicians were not penalized for billing non-specific codes (when a more specific code is available) will end. Claims must now include ICD-10-CM codes to the highest level of specificity possible based on documentation.
