About F68.10

F68.10 is the ICD-10-CM diagnosis code for factitious disorder imposed on self, unspecified. It belongs to category F68 (other disorders of adult personality and behavior), block F60-F69 (disorders of adult personality and behavior) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within F68.1, choose F68.10 (unspecified) only when documentation doesn't support a more specific option: with predominantly psychological signs and symptoms (F68.11), with predominantly physical signs and symptoms (F68.12) and with combined psychological and physical signs and symptoms (F68.13).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 883 (Disorders of Personality and Impulse Control, relative weight 1.7697), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 301.51 (chronic factitious illness with physical symptoms).
