About coding Erdheim's syndrome
The ICD-10-CM code for Erdheim's syndrome is E22.0 (Acromegaly and pituitary gigantism).
Within E22 (hyperfunction of pituitary gland), E22.0 is specifically for Acromegaly and pituitary gigantism. Related codes cover Hyperprolactinemia (E22.1), syndrome of inappropriate secretion of antidiuretic hormone (E22.2), other hyperfunction of pituitary gland (E22.8) and unspecified (E22.9).
Don't report E22.0 together with the conditions in its Excludes1 note: constitutional gigantism (E34.4), constitutional tall stature (E34.4) and increased secretion from endocrine pancreas of growth hormone-releasing hormone (E16.8).
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 E22.0)
