c. Primary Malignancy of Hematopoietic and Lymphatic Tissue.
(1) Malignancy of hematopoietic and lymphatic tissue is always coded to
2.-28.9 series with appropriate fifth digit where required, unless it is st ated to be
(2) For malignancy of hematopoietic and lymphatic tissue "in remission", a V67
with an additional code from categories V1.6-V1.7, as applicable, will be used.
d. Patient Admitted Solely and Specifically for Radiotherapy Session or for
(1) Patients admitted solely and specifically for radiotherapy and no other
treatment, use code V58. as principal diagnosis.
(2) Patients admitted solely for chemotherapy and no other treatment, use code
V58.1 as principal diagnosis.
(3) The present primary and any secondary malignancies should be classified
supplementally. If either or both neoplasms have been eradicated, the personal history
of malignancy should be coded.
e. Metastatic Cancer.
(1) If the primary malignancy is no longer present, identify the previous primary
site using the proper code within the V1 category. In such cases, do not assign the
code for "primary site unknown."
EXAMPLE: Metastatic carcinoma to lung from breast. Bilateral radical mastectomy
performed 6 months ago.
Code to : Secondary neoplasm of lung (197.) and personal history of malignant
neoplasm of breast (V1.3).
(2) Cancer described as "metastatic from" a site should be interpreted as
primary of that site.
EXAMPLE: Metastatic carcinoma from breast.
Code to : Primary malignant neoplasm of breast (174.9). Secondary neoplasm of
unspecified site (199.1).
(3) Primary site unknown. When the primary site is unknown, code to the
unspecified site for the morphological type involved; for example, carcinoma (199.1),
melanoma (172.9), adenocarcinoma (199.1), osteosarcoma (17.9), and fibrosarcoma
