Diagnosis coding. Valid ICD-10 codes are required for services on or after October 1, 2015, for everyone covered by HIPAA. ICD-10 does not change CPT coding for outpatient procedures and physician services. See the AMA's CPT code reference (external site).
Effective dates. The current regulations and methodologies took effect in March 2008, March 2012 and February 2020. Values apply by the calendar year of the date of service. Medical Fee Guide (MFG) materials do not include procedure descriptors.
Regulation spotlight — ASC implants. To speed processing of Form C-51, ambulatory surgery centers should list the exact implants on the invoice, in the body of the operative report, and in a separate paragraph at the end of the report.
