Coding Polycythemia in ICD-9-CM and ICD-10-CM

THE TABLE BELOW illustrates how polycythemia is broken down in ICD-9-CM and ICD-10-CM.

ICD-9-CM INDEX TO DISEASES

Polycythemia (primary) (rubra) (vera)

(M9950/1) 238.4

… secondary 289.0

ICD-10-CM INDEX TO DISEASES AND INJURIES

Polycythemia (secondary) D75.1

… -vera D45

Based on this information, a facility might question whether cases of polycythemia without further specification are currently being reported to the most appropriate code in ICD-9-CM or whether cases of polycythemia without further specification will be reported to the most appropriate code in ICD-10-CM. A facility might identify a need to improve documentation of this condition in order to ensure that it is reported with the most accurate and appropriate code.

Neoplasms of the Liver

In ICD-10-CM there are unique codes for liver cell carcinoma, hepatoblastoma, angiosarcoma of liver, and other sarcomas of liver. When coding these conditions in ICD-10-CM, it is useful to have an awareness of the different codes for primary malignant neoplasms of the liver. ¢
