Highlights of AHA’s Coding Clinic  Fourth Quarter 2024 Release for ICD-10-CM and ICD-10-PCS 

The Fourth Quarter 2024 newsletter of AHA Coding Clinic for ICD-10-CM and ICD-10-PCS was released October 1, 2024. Let’s explore some of the highlights!

The fourth quarter newsletter provides a summary of Fiscal Year (FY) 2025 ICD-10-CM and ICD-10-PCS changes effective October 1, 2024. There are 252 new ICD-10-CM codes and 371 new ICD-10-PCS codes. In addition, there are 13 revised and 36 deleted ICD-10-CM codes. There are no revised ICD-10-PCS code titles, and 61 ICD-10-PCS codes have been deleted from the classification.  

Within ICD-10-CM, a new subcategory has been created to identify three classes of obesity, which is defined by excessive fat deposits that can impair an individual’s health status. Obesity is a chronic complex disease in adults and children that can cause an intensified risk of heart disease, diabetes mellitus type 2, hypertension, high cholesterol, breathing issues such as asthma and sleep apnea, problems with reproduction, joint disease, and certain cancers. There are factors that can contribute to excessive weight gain, such as genetics, physical activity levels, eating patterns, sleep routines, and the use of certain medications. The new classes differentiate between low, moderate, and high-risk obesity based on a patient’s body mass index (BMI).  

Additionally, four categories of Z codes have been updated, including a new code for an encounter for sepsis-focused post-acute care to aid in recovery for patients who have been successfully treated for sepsis, and 2 new social determinant of health codes to address insufficient health insurance coverage and insufficient welfare support.  

Within ICD-10-PCS, table 5A0, Assistance of Extracorporeal Circulatory Filtration, now includes duration, function, and qualifier values to capture circulatory filtration when used during percutaneous thrombectomy.  

The newsletter also includes 17 questions and answers related to the following topics:
