ICD-10 will affect all specialties, some more than others

As we approach the ICD-10 transition deadline on October 1, 2015, members from all corners of the healthcare industry are busily preparing and testing for the upcoming rollout. From a technical perspective, this means that systems must be updated to accommodate transferring the new codes.

No small undertaking, this has been compared to the changes required to update legacy computer systems to be compatible with Y2K date formats. Likewise, physicians and other healthcare professionals who use these codes and have memorized their most frequently used ICD-9 codes will need become familiar with the expanded code set.

In a previous post, I indicated that there are almost five times as many ICD-10 codes compared to ICD-9. Adding to the challenge, the format of ICD-10 codes is significantly different than ICD-9, with similar diagnoses having complete different codes. On top of that, not all specialties receive equal weight – some specialties have a disproportionate number of new codes and rules. However, the switch will no doubt be an endeavor for practitioners of any specialty.

The ICD-10 superbill template published by the American Academy of Family Practice is 9 pages, up from 2 in ICD-9. In addition to more codes, the mappings from one code set to another can also be more complicated with incomplete or non-reciprocal mappings.

A recent study in the Journal of the American Medical Informatics Association suggests that the specialties that will experience the most significant impact include obstetrics, psychiatry, and emergency medicine. Specialties that deal with musculoskeletal disease and injuries will will also encounter significant challenge.

Practice Fusion aims to ease the transition process with coding tools to help you get from familiar ICD-9 codes to the appropriate ICD-10 counterpart. We also will be publishing a series of blog posts that focus on common codes for each specialty, and how they will map to the new ICD-10 codes.

Differences between ICD-9 codes and ICD-10 codes:

ICD-9-CM ICD-10-CM
3-5 Characters in length 3-7 Characters in length
First character may be alpha or numeric, characters 2-5 are numeric Character 1 is alpha; Characters 2 and 3 are numeric; characters 4-7 are alpha or numeric
Less specificity Greater specificity
Laterality not specified Laterality specified (e.g. left versus right)
Limited space for new codes Flexibility to add new codes
