Coding Changes in DSM-IV-TR Since May 2000 Publication
There have been two changes in diagnostic coding that affect the Diagnostic and Statistical Manual, Fourth Edition, Text Revision (DSM-IV-TR) codes themselves. The first, effective October 1, 2004, is that the code for Narcolepsy has been changed to 347.00 from 347. The second, effective October 1, 2003, is that code for Age-Related Cognitive Decline has been changed to 780.93 from 780.9.
There have been two changes in diagnostic coding, which reflect changes in general medical condition codes, that impact DSM-IV-TR coding.
Dementia Due to Parkinson's Disease: on Axis III, one should now code: 331.82 Dementia with Lewy Bodies
Dementia Due to Pick's Disease: on Axis III, one should now code 331.11 Pick's disease.
