ICD-10 codes consists of three to seven characters, while ICD-9 contained three to five digits. The biggest difference between the two code structures is that ICD-9 had 14,4000 codes, while ICD-10 contains over 69,823. Because ICD-10 codes have increased in character length, the number of codes available for use has been greatly expanded. One of ICD-9’s issues is that some chapters are full and, thus were limited in the ability to add new codes.
Last week we discussed how ICD-10-CM allows for a greater level of specificity and clinical detail.
This week, let’s take a little bit deeper look at how ICD-10 differs from ICD-9, and how the new codes are organized. Last week we provided an overview of ICD-10 and ran through some of the new features of the codeset.
