About F50.019

F50.019 is the ICD-10-CM diagnosis code for Anorexia nervosa, restricting type, unspecified. It belongs to category F50 (eating disorders), block F50-F59 (behavioral syndromes associated with physiological disturbances and physical factors) 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 F50.01, choose F50.019 (unspecified) only when documentation doesn't support a more specific option: mild (F50.010), moderate (F50.011), severe (F50.012), extreme (F50.013) and in remission (F50.014).

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 was added in FY2025, effective October 1, 2024.
