About coding Gangliocytic paraganglioma
The ICD-10-CM code for Gangliocytic paraganglioma is D13.2 (Benign neoplasm of duodenum). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on D13.2.
Within D13 (benign neoplasm of other and ill-defined parts of digestive system), D13.2 is specifically for benign neoplasm of duodenum. Related codes cover esophagus (D13.0), stomach (D13.1), other and unspecified parts of small intestine (D13.3), liver (D13.4), extrahepatic bile ducts (D13.5), pancreas (D13.6), endocrine pancreas (D13.7) and ill-defined sites within the digestive system (D13.9).
Don't report D13.2 together with the conditions in its Excludes1 note: benign carcinoid tumor of the duodenum (D3A.010).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
