I understand that International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes are updated on October 1, 2023. Are there any changes in ICD-10-CM that we should be aware of for urology?

Great question; many are not aware that the ICD-10-CM year runs from October 1 until the end of September. For the 2024 edition, effective October 1, 2023, there were 395 new codes, 25 deletions, and 13 substantive revisions. Most of the changes will not affect the vast majority of urology practices. Below is a list of code additions to chapter 14, “Diseases of the genitourinary system N00-N99.”^1,2

Code N35.812 (Other urethral bulbous stricture, male) was revised to N35.812(Other bulbous urethral stricture, male).

It should be noted that the list above is not inclusive. ICD-10-CM coding denials have been increasing across the country as payers continue to refine edits. The most common denial is for nonspecific ICD-10-CM codes in families with more specific coding options available. We encourage you to check with your EHR vendor to make sure all new codes and changes have been incorporated into your system.Further, it is imperative for at least one in your office to have access to all changes made to ICD-10-CM either through a system like AUACodingtoday.com and/or downloading these changes from CMS using the link above.We encourage you to review your ICD-10-CM coding patterns, shortcuts, and definitions throughout the year.
