About coding black adenoma
The ICD-10-CM code for black adenoma is D35.00 (Benign neoplasm of unspecified adrenal gland).
Within D35.0, choose D35.00 (unspecified adrenal gland) only when documentation doesn't support a more specific option: right adrenal gland (D35.01) and left adrenal gland (D35.02).
Use an additional code to identify any functional activity.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
