The Centers for Medicare and Medicaid Services released changes to ICD-10-CM codes effective as of Oct. 1. Changes to some mental, behavioral and neurodevelopmental disorders codes are among 360 new, 142 deleted and 226 revised diagnostic codes for fiscal year 2018.
Most of the changes to mental health codes relate to new specifiers, which occur after the decimal point of the parent code, for substance abuse disorders. Psychologists can now select a specific ICD-10-CM code when a patient is in remission from abuse of a variety of substances, including alcohol, opioids and cannabis. These specifiers will allow for more accurate diagnostic recording.
An additional code, for avoidant/restrictive food intake disorder, has been moved from “Other specified eating disorder” to “Other eating disorder,” classifying it alongside Binge eating disorder (F50.81). Additional changes were made to diagnostic codes for pain management and neurology.
Psychologists practicing in healthcare settings where the use of diagnostic codes other than the mental health codes is common may find it helpful to refer to the FY18 Conversion Tableopens in new window available for download from the Center for Disease Control.
