About coding Dysorexia
The ICD-10-CM code for Dysorexia is R63.0 (Anorexia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R63.0.
Within R63 (symptoms and signs concerning food and fluid intake), R63.0 is specifically for Anorexia. Related codes cover Polydipsia (R63.1), Polyphagia (R63.2), feeding difficulties (R63.3), abnormal weight loss (R63.4), abnormal weight gain (R63.5), Underweight (R63.6) and other symptoms and signs concerning food and fluid intake (R63.8).
Don't report R63.0 together with the conditions in its Excludes1 note: anorexia nervosa (F50.0-) and loss of appetite of nonorganic origin (F50.89).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
