Crosswalk from ICD-11 mental, behavioural and neurodevelopmental disorders to ICD-10 for clinician use
Crosswalk from ICD-11 
mental, behavioural and 
neurodevelopmental disorders 
to ICD-10 for clinician use
This table provides a crosswalk or mapping specifically designed for use by clinicians from 
categories in this ICD-11 chapter on mental, behavioural and neurodevelopmental disorders to 
the nearest equivalent ICD-10 category. This will be useful, for example, in settings where there 
has been a shift to use of ICD-11 for clinical purposes, but where data or health reporting systems 
are still in transition and require the use of ICD-10 codes.
Use of this table assumes that the clinician has already made their diagnosis according to the 
ICD-11 CDDR. This table is not valid for mapping categories from the ICD-10 mental and 
behavioural disorders to ICD-11 because it does not reflect the full content of the ICD-10 mental 
and behavioural disorders.
This crosswalk is not intended for use in health statistics or in the coding of medical records 
because, in a substantial number of instances, selecting among multiple possible ICD-10 
categories depends on clinical information that will not be available in those contexts. Additional 
information to assist clinicians in making these distinctions is provided in the “Notes” column 
on the right.
In the table that follows, the ICD-11 categories are listed in the left column in the order in which 
they appear in the classification. The closest available ICD-10 category to represent that ICD-11 
disorder (i.e. the preferred code) is provided as the first entry in the middle column. Many of these 
are 4-character ICD-10 codes (e.g. F80.1), but in other instances a 3-character code (e.g. F20) or 
a 5-character code (e.g. F10.24) best captures the ICD-11 category. Where ICD-10 5-character 
codes appear, these are taken from The ICD-10 classification of mental and behavioural disorders: 
clinical descriptions and diagnostic guidelines, which in some cases include more detailed coding 
options than the statistical version of ICD-10.
Data systems and/or reporting requirements in some health systems and countries may require 
that 4-character ICD-10 codes are used if they are available, so that a 3-character code is not 
accepted if a 4-character subcategory exists. Similarly, many data systems do not accept 5-character 
ICD-10 codes, allowing a maximum of 4 characters. In situations in which the nearest equivalent 
ICD-10 category is not a 4-character code, a 4-character coding option is also provided.
Additional coding or reporting requirements vary widely across settings and countries. 
The mappings provided here may therefore require adjustment based on the requirements of the 
specific clinical setting. This crosswalk is not intended to contravene any guidance that may be 
provided by the relevant health system or government.
In a couple of specific instances (e.g. ICD-11 Body dysmorphic disorder), coding information 
provided in The ICD-10 classification of mental and behavioural disorders: clinical descriptions and 
diagnostic guidelines is not consistent with current evidence. The mappings provided in the table 
are consistent with the ICD-11 conceptualizations in these cases, with such deviations described 
in the “Notes” column.
