Background
The ICD-9-CM codes are updated annually as stated in the Medicare Claims Processing Manual, Chapter 23 (Fee Schedule Administration and Coding Requirements), Section 10.2 (Relationship of ICD-9-CM Codes and Date of Service).
CMS issued CR 6520 as a reminder that the annual ICD-9-CM coding update will be effective for dates of service on or after October 1, 2009 (for institutional providers, effective for discharges on or after October 1, 2009).
Remember that an ICD-9-CM code is required for all professional claims (including those from physicians, non-physician practitioners, independent clinical diagnostic laboratories, occupational and physical therapists, independent diagnostic testing facilities, audiologists, ambulatory surgical centers), and for all institutional claims; but is not required for ambulance supplier claims.
