This was in a newsletter from ValueOptions and I believe it responds to an age old question I have received for many years as to why Clinicians are taught in school to diagnose with DSM when the standard for billing has always been ICD.
Both DSM and ICD codes are used for diagnosis, but per HIPAA, ICD must be used for billing purposes. DSM-5 utilizes ICD-9-CM and ICD-10-CM coding depending on the date of service. The move from ICD-9 to ICD-10 is a rather large change. Some highlights include:
- · The number of characters are increasing from 3 to 5 characters to 7 characters
- · Codes can be alpha or numeric on any character
- · The number of codes is growing from approximately 14,000 to 69,000 codes
- · The concept of one to many is introduced with the possibility of a single ICD-9 code now having multiple ICD-10 codes and descriptions
- · Some concepts will be retired – an example is substance dependency where dependency is replaced by use and specific substances are documented vs. polysubstance
Overall, by using ICD-10, documentation should improve
For purposes of claims payment, the correct ICD diagnosis coding should be utilized based on the date of service. For dates of service prior to October 1, 2015, the ICD-9 coding format should be utilized. For dates of service October 1, 2015 and later the ICD-10 diagnosis coding should be the format utilized. Claims will need to be split between these two dates if submitting for a range of dates.
This applies to all claims regardless of the method of submission.
In Addition, I found this little crosswalk that I thought might be useful. For more information on this, contact our office at 877-891-9352
