About coding liver teratoma
The ICD-10-CM code for liver teratoma is C22.7 (Other specified carcinomas of liver). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on C22.7.
Within C22, choose C22.7 (Other specified carcinomas of liver) only when documentation doesn't support a more specific option: liver cell carcinoma (C22.0), intrahepatic bile duct carcinoma (C22.1), Hepatoblastoma (C22.2), Angiosarcoma of liver (C22.3), other sarcomas of liver (C22.4), malignant neoplasm of liver, primary, unspecified as to type (C22.8) and malignant neoplasm of liver, not specified as primary or secondary (C22.9).
Use an additional code to identify: alcohol abuse and dependence (F10.-), hepatitis B (B16.-, B18.0-B18.1) and hepatitis C (B17.1-, B18.2).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
