Get ready for the new ICD-10 coding updates for 2024 

On June 16, the Centers for Disease Control and Prevention (CDC) released the ICD-10-CM codes for the 2024 fiscal year (FY). This diagnosis coding update included 395 additions, 25 deletions, and 22 code revisions. Also, the CMS updated the 2024 addendum, code descriptions in tabular order, and code tables, tabular list, and index.  

These 2024 ICD-10-CM codes will be for discharges and patient encounters from October 1, 2023, through September 30, 2024.

Staying updated on ICD-10 coding changes is essential for medical practices. Being well-informed about these changes can ensure accurate and precise coding, facilitating proper reimbursement, reducing claim denials, and improving revenue cycles.  

Additionally, medical practices benefit from staying current on these ICD-10 coding changes as it helps them maintain compliance with regulatory requirements, avoid penalties, and enhance overall patient care.  

Here is a highlight of the chapters with significant revisions of the ICD-10-CM Coding Updates in the 2024 FY  

Chapter 2: Neoplasms  

This chapter has 21 additions and 2 deletions. There is a new code regarding familial adenomatous polyposis (FAP). Another code is set to precisely capture benign neoplasms occurring in other parts of the digestive system.   

In the Table of Neoplasms, code D13.9 is now represented as D13.99, encompassing a limited number of relevant body areas. Additionally, new Z codes facilitate reporting of family history related to FAP.  

Furthermore, this chapter includes new codes for desmoid tumors (D48.11-) and other specified neoplasms of uncertain behavior in connective and other soft tissues (D48.19).  

Chapter 4: Diseases of the endocrine system  

Regarding endocrine, nutritional, and metabolic diseases, there are 18 additions and 3 deletions. A new subcategory in this chapter includes several new codes to identify individuals with Autosomal dominant hypocalcemia (ADH).   

Also, this chapter adds new codes designed to report different lipid storage disorders. Additionally, there are new codes to enhance the reporting of leukodystrophies. Among them is a new code for lysosome-associated membrane protein 2 (LAMP2) deficiency (E74.05).   

In addition, there are new codes regarding metabolic disorders. These include codes E88.810-E88-819, which allows the identification of insulin-resistant metabolic syndrome types A and B and unspecified insulin resistance. Lastly, there is a new code (E88.A) for wasting disease (syndrome) caused by an underlying condition.   

Chapter 6: Diseases of the nervous system  

This chapter includes 24 additions and 2 deletions without ICD-10 changes. Among them are new subcategories and codes for reporting chronic migraine and differentiators to identify whether the pain is manageable.   

Regarding Parkinson’s disease, this chapter includes five new codes:   

  • G20.A1: Parkinson’s disease without dyskinesia, without mention of fluctuations  
  • G20.A2: Parkinson’s disease without dyskinesia, with fluctuations  
  • G20.B1: Parkinson’s disease with dyskinesia, without mention of fluctuations  
  • G20.B2: Parkinson’s disease with dyskinesia, with fluctuations  
  • G20.C: Parkinsonism, unspecified  

Chapter 7: Diseases of Eye and Adnexa  

This chapter includes 34 additions. Above all, under the category H50 Other strabismus, new subcategories, and codes are in this chapter to facilitate reporting extraocular muscle entrapment. These new codes (H50.62 – H50.68) provide specific information regarding the affected part of the extraocular muscle and the laterality.  

Also, there are additional tabular modifications in this chapter. A new subcategory and codes are included under category H36 Retinal disorders in disease classified elsewhere, specifically for reporting proliferative and non-proliferative sickle-cell retinopathy.   

Moreover, new codes are available under H54, Blindness and low vision, and H57, Other disorders of the eye and adnexa. These updates aim to enhance the accuracy and specificity of reporting these particular conditions.  

Chapter 13: Diseases of Musculoskeletal System and Connective Tissue

Among the revisions, chapter 13 demonstrates the second-highest number of changes, incorporating 36 additional codes. For improved reporting, new regulations are added under new subcategories M80.0B Age-related osteoporosis with current pathological fracture and .0.8B Other osteoporosis with current pathological fracture, pelvis.  

The reasons for these changes are age-related and other osteoporosis with left, right, and unspecified pelvis sites.  

Chapter 17: Congenital Malformations, Deformations, and Chromosomal Abnormalities  

There are 22 additions, 2 deletions, and 6 changes for congenital malformations, deformations, and chromosomal abnormalities. Among all the changes, there are:  

  • New Q codes and inclusion terms to allow for more precise identification of Alagille syndrome  
  • New codes under Q75: Other congenital malformations of skull and face bones  
  • New codes under Q87.8: Other specified congenital malformation syndromes not elsewhere classified  
  • Code Q93.52 added to designate Phelan-McDermid syndrome  

Chapter 20: External Cause of Morbidity   

Chapter 20 has the most updates, featuring an impressive addition of 123 new codes.   

The expansion focuses on foreign bodies that enter or pass through a natural opening, encompassing button batteries, plastic objects, glass items, magnetic and non-magnetic metal objects, rubber bands, food items, non-organic substances, and sharp objects.  

Chapter 21: Factors Influencing Health Status and Contact with Health Services  

In total, this chapter includes 30 new codes and 6 deletions. These deletions are due to expanded diagnosis codes. Among these updates are: 

  • A new code for reporting a child welfare exam (Z02.84)
  • Two codes under Z05.8 to report observation/evaluation of a newborn
  • One code to identify resistance to carbapenem
  • New Z22.34 codes to report carriers of other specified bacterial diseases

There is also a new code for acute HIV infection syndrome and HIV pre-exposure prophylaxis (PrEP). The updates also include new Z codes to provide specificity for family history of adenomatous polyps for individuals with the familiar risk factor and to report additional social determinants of health.
