Pub. 100-04 Medicare Claims Processing: Transmittal 95
Guidance that instructs carriers and DMERCs to eliminate the 90-day grace period for billing discontinued ICD-9-CM codes. Medicare has permitted a 90-day grace period after implementation of ICD-9-CM diagnosis codes, so providers can ascertain the new codes and learn about the discontinued codes. Providers must now bill using the diagnosis code valid for the date of service, effective for dates of service on and after October 1, 2004.
