About coding choroid plexus papilloma
The ICD-10-CM code for choroid plexus papilloma is D33.0 (Benign neoplasm of brain, supratentorial). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D33.0.
Within D33 (benign neoplasm of brain and other parts of central nervous system), D33.0 is specifically for benign neoplasm of brain, supratentorial. Related codes cover brain, infratentorial (D33.1), brain, unspecified (D33.2), cranial nerves (D33.3), spinal cord (D33.4), other specified parts of central nervous system (D33.7) and central nervous system, unspecified (D33.9).
Don't report D33.0 together with the conditions in its Excludes1 note: benign neoplasm of fourth ventricle (D33.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
