ICD-10 Chapter V — Mental and Behavioural Disorders
Chapter V groups mental and behavioural disorders into ten substantive blocks, each covering a family of related conditions, plus a separate residual category (F99) for mental disorder that is not otherwise specified. Codes run from three characters (a category, e.g. F20) to four characters (a subcategory, e.g. F20.0) and occasionally five. This Learning Lab now offers fully authored pilots for all ten substantive blocks — F00-F09, F10-F19, F20-F29, F30-F39, F40-F48, F50-F59, F60-F69, F70-F79, F80-F89, and F90-F98 — each its own self-contained learning space — plus the chapter-level residual category F99, authored separately and never folded into any block's own chooser or category list.
