About coding Renon-Delille syndrome
The ICD-10-CM code for Renon-Delille syndrome is E23.3 (Hypothalamic dysfunction, not elsewhere classified).
Within E23 (hypofunction and other disorders of the pituitary gland), E23.3 is specifically for hypothalamic dysfunction, not elsewhere classified. Related codes cover hypopituitarism (E23.0), drug-induced hypopituitarism (E23.1), diabetes insipidus (E23.2), other disorders of pituitary gland (E23.6) and disorder of pituitary gland, unspecified (E23.7).
Don't report E23.3 together with the conditions in its Excludes1 note: Prader-Willi syndrome (Q87.11) and Russell-Silver syndrome (Q87.19).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for E23.3)
