About the C54 Code Range
ICD-10 code C54 and its subcategories are used to classify malignant neoplasms of the corpus uteri, specifying cancer locations within the uterine body. These codes precisely identify tumors affecting various parts like the isthmus, endometrium, myometrium, fundus, overlapping sites, or unspecified areas of the corpus uteri.
The main code, C54, covers general malignant neoplasms of the corpus uteri. For more detailed coding, subcodes such as C54.0 represent malignant tumors of the isthmus uteri, including conditions known as rhabdomyosarcoma of isthmus uteri. C54.1 identifies malignant neoplasms of the endometrium, with synonyms like endometrial carcinoma, serous carcinoma, and carcinosarcoma, helping coders match diagnoses accurately. C54.2 denotes malignancies in the myometrium, including primary rhabdomyosarcoma of the uterine muscle layer, while C54.3 targets cancers of the uterine fundus. The code C54.8 covers overlapping malignant sites within the uterine body. When the tumor location is unknown or unspecified, C54.9 is used, incorporating a range of associated malignant types such as leiomyosarcoma and undifferentiated carcinoma. These ICD-10 codes facilitate precise documentation and help healthcare providers code complex uterine cancers efficiently.
