Annual ICD-9 diagnosis code revisions take effect in October

From the October ACP Internist, copyright 2010 by the American College of Physicians

By Debra Henley Lansey

As on every Oct. 1, there are additions and deletions to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis code set. Practices need to review their frequently used diagnosis codes and then prepare to update their documents and systems to accommodate the code changes.

Q: Are there many modifications that apply to internists?

A: Yes, even more than last year. In addition to the code changes listed here, there are also numerous updates to category headings and the exclusions notes that appear in the subcategories. Although this article focuses on the codes that will have the greatest impact on the specialty, many others are not included here. You will want to be sure to check your ICD-9 codebook for the sections that you use most frequently.

Q: I thought that ICD-9 was being replaced. When will that happen?

A: That will be the ICD-10 coding system, the next revision of the ICD set. It is scheduled to go into effect on Oct. 1, 2013. On that date, all physician practices and other health care providers will be expected to have their systems and documents ready to use the new code set. The ICD-10 diagnosis codes will be required for use on all Health Insurance Portability and Accountability Act of 1996 (HIPAA) transactions, including outpatient claims with dates of service and inpatient claims with dates of discharge on or after Oct. 1, 2013.

Annual ICD-9 diagnosis code revisions take effect in October

ACP is preparing a series of educational pieces for its members, which will be announced and made available in the near future. Until Oct. 1, 2013, continue to use the ICD-9 codes.

Q: What are the most relevant ICD-9 code changes that I need to incorporate into my practice beginning this October?

A: Lists of the specific, relevant changes are shown below. The first list shows the deleted codes that will be invalid on and after Oct. 1, 2010 and are being replaced with new, more specific codes found in the second list. Also note that there are a number of “V-codes” (sometimes called status codes) for recording a patient’s personal medical history and for delineating a patient’s body mass index (BMI).

An illustrative description of a specific, relevant code change is the expansion of diagnosis code options to indicate influenza. Last year, code 488 (influenza) was expanded to a category with two new codes added: 488.0 and 488.1. These codes were created to provide data on the novel H1N1 influenza virus (also known as swine flu) and avian influenza (also known as bird flu), respectively. Each single, four-digit code has been replaced with three five-digit codes for this year.
