🗓️ Two code updates in one quarter. Both can stop clean claims cold.
▪️ October 1, 2026: the FY 2027 ICD-10-CM diagnosis codes took effect. Claims with retired or incomplete codes start bouncing right away.
▪️ January 1, 2027: the AMA's CPT 2027 code set takes effect. It has 299 new codes, 74 revised codes and 80 deleted codes.
Deleted codes are the quiet danger. A code that worked on December 31 can deny on January 2.
A simple year-end code check for ortho practices and ASCs:
1️⃣ Update EHR pick lists, superbills and favorites
2️⃣ Update the ASC charge master and fee schedules
3️⃣ Find any scheduled January cases that use deleted codes
4️⃣ Watch the first two weeks of January remits closely
Payers do not always load new codes on day one either. Watch for "invalid code" denials on correct claims and appeal them fast.
The certified coders at Medical Healthcare Solutions, Inc. (MHS) run this check for every client before each code update.
