2024 ICD-10 Diagnosis Changes, Part III

October 2, 2023

Nothing will make you appreciate the sheer number of coding changes and updates for the coming year than seeing them all listed individually. In the past two editions of Coffee & Coding, we’ve covered nearly 150 of the new codes you’ll have to begin applying, focusing on the chapters with the most extensive changes. We’ll make it (whew!) through the rest of the list this week. Then, you’ll have just enough time to catch your breath before the other, even heavier shoe drops—the new CPT codes for 2024.

As for the approximately 250 new ICD-10 codes we have yet to discuss, I’ve arranged the diagnosis changes according to their respective chapters. If you’d like a more in-depth explanation of these changes, click the link at the end of the list.
