The 6 Major Differences Between ICD-9 and ICD-10 Codes
- #1. Number of digits used. ICD-10 diagnosis codes may contain more digits than the traditional ICD-9 codes.
- #2. First Digit.
- #3. Second Digit.
- #4. Third and subsequent digits.
- #5. Ability to add new codes.
- #6. Specificity.
Is it possible that ICD-9 and ICD-10 codes will be used simultaneously?
However, most ICD-9-CM codes are still matched with multiple terms in ICD-10-CM, and there is still room for double billing during the period when the two systems will be activated simultaneously.
How do I change from ICD-10 to ICD-9?
On October 1, 2013, the ICD-9 code sets will be replaced by ICD-10 code sets. The U.S. Department of Health and Human Services issued a final rule on January 16, 2009, adopting ICD-10-CM (clinical modifier) and ICD-10-PCS (procedure coding) system.
What are GEMs and how are they used for conversion from ICD-9 to ICD-10?
The GEMs were designed to convert current ICD-9-CM codes to applicable ICD-10 codes. A “reverse lookup” of the backward mappings (ICD-10-CM/PCS to ICD-9-CM GEM, looked up by ICD-9-CM code) can be used to convert payment logic or coverage decisions from ICD-9-CM codes to ICD-10 codes.
What is a major difference between ICD-9 and ICD-10 in terms of billing process?
Code Structure: Comparing ICD-9 to ICD-10
| ICD-9-CM | ICD-10-CM |
|---|---|
| First character is numeric or alpha ( E or V) | First character is alpha |
| Second, Third, Fourth and Fifth digits are numeric | All letters used except U |
| Always at least three digits | Character 2 always numeric; 3 through 7 can be alpha or numeric |
What is difference between ICD-9 code and ICD 10 code?
ICD-9 uses mostly numeric codes with only occasional E and V alphanumeric codes. Plus, only three-, four- and five-digit codes are valid. ICD-10 uses entirely alphanumeric codes and has valid codes of up to seven digits.
When did ICD-9 transition to ICD-10?
October 1, 2015
Abstract. Objective-On October 1, 2015, the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) replaced ICD-9-CM (Ninth Revision) as the diagnosis coding scheme for the U.S. health care system.
When did ICD-9 switch to ICD-10?
CMS requires medical practices and RCM companies to make the switch from ICD-9 to ICD-10 by October 1, 2015, the last day for ICD-9 being September 30, 2015. This is not new. Organized, managed, and maintained by the World Health Organization, ICD codes are changed approximately once every 10 years.
What are ICD-10 GEM files?
The GEM files are a public domain reference mapping designed to give all sectors of the healthcare industry that use coded data a tool to convert and test systems, link data in long-term clinical studies, develop application-specific mappings, and analyze data collected during the transition period and beyond.
What maps ICD-9-CM codes to ICD-10-CM codes?
The GEMs are a tool that can be used to convert data from ICD-9-CM to ICD-10-CM and PCS and vice versa. Mapping from ICD-10-CM and PCS codes back to ICD-9-CM codes is referred to as backward mapping. Mapping from ICD-9-CM codes to ICD-10-CM and PCS codes is referred to as forward mapping.
How can you tell ICD-9 from ICD-10?
The biggest difference between the two code structures is that ICD-9 had 14,4000 codes, while ICD-10 contains over 69,823. ICD-10 codes consists of three to seven characters, while ICD-9 contained three to five digits.
