Understanding the evolving landscape of medical coding is crucial for healthcare professionals, especially when it comes to accurate diagnoses and procedures. The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) and Procedure Coding System (ICD-10-PCS) are updated annually to reflect the latest medical knowledge and ensure precise data collection. This guide breaks down the key updates for 2024 and upcoming 2025, providing a clear picture of what you need to know.
2025 ICD-10-CM and PCS Updates: What’s on the Horizon
For the fiscal year 2025, both ICD-10-CM and ICD-10-PCS are undergoing revisions. These updates are essential for coding discharges and patient encounters accurately throughout the year.
ICD-10-CM 2025: Navigating the Changes

October 1, 2024 – September 30, 2025 Discharges and Encounters:
For discharges and patient encounters spanning the entire fiscal year (October 1, 2024 to September 30, 2025), specific files are designated:
- 2025 POA Exempt Codes file: This file, crucial for Present on Admission (POA) indicator reporting, remains unchanged from the previous year.
- 2025 Conversion Table: Similarly, the conversion table for ICD-9 to ICD-10 and vice versa is also consistent with the prior year.
October 1, 2024 – March 31, 2025 Discharges and Encounters:
For the first half of the fiscal year, ending March 31, 2025, the following files are applicable:
- 2025 Code Descriptions in Tabular Order: Provides a structured, tabular listing of all diagnosis codes with their descriptions.
- 2025 Addendum: Details the specific additions, deletions, and revisions made to the ICD-10-CM code set for 2025.
- 2025 Code Tables, Tabular and Index: Offers comprehensive tables and indexes to facilitate efficient code lookup and validation.
- FY 2025 ICD-10-CM Guidelines files: Outlines the official guidelines for using and interpreting the ICD-10-CM coding system for FY 2025.
April 1, 2025 – September 30, 2025 Discharges and Encounters:
For discharges and encounters occurring in the latter half of FY 2025 (April 1, 2025 to September 30, 2025), updated code files are to be utilized. These files reflect any changes effective from April 1, 2025.
ICD-10-PCS 2025: Procedure Coding Updates
The ICD-10-PCS files for 2025 also follow a phased implementation:
October 1, 2024 – March 31, 2025 Discharges:
Use the initial set of 2025 ICD-10-PCS codes for discharges occurring between October 1, 2024 and March 31, 2025.
April 1, 2025 – September 30, 2025 Discharges:
For discharges from April 1, 2025 through September 30, 2025, employ the updated ICD-10-PCS files that incorporate revisions effective April 1, 2025.
2024 ICD-10-CM and PCS: Reflecting on the Past Year
Looking back at the 2024 updates provides context and highlights the ongoing nature of ICD-10 revisions.
ICD-10-CM 2024: Focus on Accuracy
The FY 2024 ICD-10-CM updates were primarily focused on maintaining accuracy and correcting errors within the existing code set.
October 1, 2023 – September 30, 2024 Implementation:
The 2024 ICD-10-CM codes were in effect for discharges and patient encounters from October 1, 2023 to September 30, 2024.
April 1, 2024 Update:
A notable update on April 1, 2024, addressed typographical errors within the ICD-10-CM. Importantly, no new diagnosis codes were introduced at this time. This contrasts with other years where new codes were frequently added.
ICD-10-PCS 2024: Expanding Procedure Codes
In contrast to the CM updates, ICD-10-PCS for 2024 saw the addition of new codes to enhance specificity in procedure reporting.
October 1, 2023 – September 30, 2024 Implementation:
The 2024 ICD-10-PCS codes were utilized during this period.
April 1, 2024 Update:
The April 1, 2024 update brought 41 new procedure codes into effect. This expansion aimed to provide more granular detail in coding medical procedures.
ICD-10 Updates in Previous Years: A Quick Glance
To further illustrate the evolution of ICD-10, let’s briefly review updates from 2023 back to 2021.
2023 ICD-10-CM and PCS: Addressing Social Determinants of Health
ICD-10-CM 2023:
- Introduced 42 new diagnosis codes effective April 1, 2023.
- These codes were significant as they focused on capturing health-related social needs (HRSNs). HRSNs are adverse social conditions that negatively impact health outcomes. Recognizing these factors is vital for holistic patient care and addressing social determinants of health.
ICD-10-PCS 2023:
- Included 34 new procedure codes from April 1, 2023.
2022 ICD-10-CM and PCS: Responding to the COVID-19 Pandemic
ICD-10-CM 2022:
- Implemented 3 new diagnosis codes on April 1, 2022 (Z28.310, Z28.311, and Z28.39).
- These codes were specifically for reporting COVID-19 vaccination status during the public health emergency, highlighting the adaptability of ICD-10 to emerging health crises.
ICD-10-PCS 2022:
- Added 9 new procedure codes on April 1, 2022, related to COVID-19 therapeutics and vaccines.
- Further updates included 2 additional procedure codes (ERRATA). These additions demonstrated the rapid response of the coding system to new medical interventions developed during the pandemic.
2021 ICD-10-CM and PCS: Initial COVID-19 Coding
ICD-10-CM 2021:
- Introduced 6 new diagnosis codes effective January 1, 2021, in response to the COVID-19 public health emergency. These were among the earliest codes developed to specifically track and categorize COVID-19 related diagnoses.
ICD-10-PCS 2021:
- Implemented 21 new procedure codes on January 1, 2021, for COVID-19 therapeutics and infusions. This marked the initial significant expansion of procedure codes to address the treatment of COVID-19.
Conclusion: Staying Updated with ICD-10 is Essential
The annual updates to ICD-10-CM and PCS are a continuous process, ensuring the coding systems remain relevant and accurate. While specific “Hospice Diagnosis Codes 2024” are not explicitly detailed as a separate category in these general updates, understanding the broader changes to diagnosis and procedure codes is vital for all areas of healthcare, including hospice and palliative care.
Staying informed about these updates, especially the timely implementation dates, is crucial for accurate medical coding, billing, and data analysis. Regularly consulting the official ICD-10 resources and updates from organizations like the CDC and CMS is recommended for all healthcare professionals involved in coding and documentation.
