2018 ICD-10 Updates2018 ICD-10 updates will soon go into effect on October 1st. These changes will impact encounters for dates of service October 1, 2017 through September 30, 2018. It is imperative that your organization has up-to-date coding resources and a keen understanding of the changes that will impact your reimbursement!

This year’s ICD-10 updates include 363 new codes, 142 deleted codes, and 250 code revisions.

Here are notable highlights of the 2018 updates:

  • New musculoskeletal chapter codes to represent lumbar stenosis with or without neurogenic claudication
  • New neoplasm chapter codes to identify all types of mast cell neoplasms, such as: malignant mast cell neoplasm, aggressive systemic mastocytosis, mast cell sarcoma, and other types.
  • 72 new codes to identify non-pressure chronic ulcers that have penetrated muscle and bone tissue without necrosis
  • New endocrine chapter codes to identify diabetes mellitus with ketoacidosis
  • Myocardial Infarction codes now include specificity for type 1, type 2, and “other” MIs
  • Two new subcategories have been created for heart failure to include specificity for right heart failure as well as chronicity, right heart failure due to left heart failure, biventricular heart failure, high output heart failure, and end-stage heart failure
  • 17 new antenatal screening codes to identify specific screenings administered to pregnant patients, including testing for fetal growth retardation and chromosomal abnormalities
  • New convention update regarding the use of the term “with.” The convention now specifies that, when another existing Guideline specifically requires a documented linkage between two conditions, the word “with” does not suffice. Providers will have to make it clear within their clinical documentation the cause-and-effect relationship between conditions that are related.
  • Updates to the mental health chapter include explanatory information regarding substance abuse remission codes to include specificity for severity (i.e. mild, moderate, severe) in an effort to better align ICD-10-CM with the APA’s DSM-5
