Other specified types of T/NK-cell lymphoma

In Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96), chapter 2: Neoplasms

14 billable codes under C86: all are a CC; all map to HCC 20 (Lung and Other Severe Cancers), HCC 19 (Myelodysplastic Syndromes, Multiple Myeloma, and Other Cancers).A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.
