 Today’s the day Yes, the annual switching of the diagnosis codes takes place today. Are you aware that there are hundreds of new changes (21 deletions, 30 revisions, and 273 new codes) affecting multiple chapters? Are you prepared? Take time right now and check out what is happening before you start getting claim denials. You need to update your coding tools and internal forms, and begin working on clinical documentation improvement processes to ensure providers are all set to take on these changes.

  • Code description revisions were done to identify types of psychodysleptics [hallucinogens] (T40.906-) and parasympathomimetrics [cholinergics] (T44.1X6-).

  • New codes for specific types of heatstroke (T67.09X-) have been added (i.e., heatstroke and sunstroke, exertional type, other type)

Chapter 20: External Causes of Morbidity (V00-Y99)

There are more than code changes. The  2020 Official ICD-10-CM Coding Guideline Changes  are also revised! Be sure to review these changes so you are ready for any coding and documentation questions that may arise. CLICK HERE to read about it.

  • Care for neurostimulator devices in any anatomic site may now be reported with revised code Z45.42. Previously, the code description limited reporting based on anatomic site (i.e., brain, peripheral nerve, spinal cord), but the revised code removed specific sites, making it eligible to report wherever the device is located.
  • A new code to report the presence of a neurostimulator (Z96.82) has been added to the codeset. Don’t forget, when the encounter is not related to assessment or management of the device Z96.82 “Presence of neurostimulator” may be reported; however, when the encounter is all about testing, interrogating, or adjusting the device, it should be reported with Z45.42.
  • A simple revision for consistency was made to Body Mass Index 50.0-59.0, adult (Z68.43) to change 50 to 50.0.
  • A new code has been added to report an encounter to health counseling related to travel (Z71.84)
  • Personal history of” indicates the patient once had the condition or disease but it no longer exists and they do not receive any on-going or periodic treatment for it. New codes have been added to subcategory Z86.00- “Personal history of in-situ neoplasm” (a pre-malignant growth that hasn’t spread) for certain anatomic sites (i.e., unspecified genital organs, oral cavity, esophagus, stomach, unspecified digestive organs, middle ear, respiratory system, melanoma in-situ, in-situ neoplasm of skin)

Artificial Intelligence in Healthcare - A Medical Coder's Perspective
December 26th, 2023 - Aimee Wilcox
We constantly hear how AI is creeping into every aspect of healthcare but what does that mean for medical coders and how can we better understand the language used in the codeset? Will AI take my place or will I learn with it and become an integral part of the process that uses AI to enhance my abilities? 
Specialization: Your Advantage as a Medical Coding Contractor
December 22nd, 2023 - Find-A-Code
Medical coding contractors offer a valuable service to healthcare providers who would rather outsource coding and billing rather than handling things in-house. Some contractors are better than others, but there is one thing they all have in common: the need to present some sort of value proposition in order to land new clients. As a contractor, your value proposition is the advantage you offer. And that advantage is specialization.
ICD-10-CM Coding of Chronic Obstructive Pulmonary Disease (COPD)
December 19th, 2023 - Aimee Wilcox
Chronic respiratory disease is on the top 10 chronic disease list published by the National Institutes of Health (NIH). Although it is a chronic condition, it may be stable for some time and then suddenly become exacerbated and even impacted by another acute respiratory illness, such as bronchitis, RSV, or COVID-19. Understanding the nuances associated with the condition and how to properly assign ICD-10-CM codes is beneficial.
Changes to COVID-19 Vaccines Strike Again
December 12th, 2023 - Aimee Wilcox
According to the FDA, CDC, and other alphabet soup entities, the old COVID-19 vaccines are no longer able to treat the variants experienced today so new vaccines have been given the emergency use authorization to take the place of the old vaccines. No sooner was the updated 2024 CPT codebook published when 50 of the codes in it were deleted, some of which were being newly added for 2024.
Updated ICD-10-CM Codes for Appendicitis
November 14th, 2023 - Aimee Wilcox
With approximately 250,000 cases of acute appendicitis diagnosed annually in the United States, coding updates were made to ensure high-specificity coding could be achieved when reporting these diagnoses. While appendicitis almost equally affects both men and women, the type of appendicitis varies, as dose the risk of infection, sepsis, and perforation.

Medicare Guidance Changes for E/M Services
October 11th, 2023 - Wyn Staheli
2023 brought quite a few changes to Evaluation and management (E/M) services. The significant revisions as noted in the CPT codebook were welcome changes to bring other E/M services more in line with the changes that took place with Office or Other Outpatient Services a few years ago. As part of CMS’ Medicare Learning Network, the “Evaluation and Management Services Guide” publication was finally updated as of August 2023 to include the changes that took place in 2023.
