If the site of the primary cancer is not documented, the coder will assign a code for the metastasis first, followed by C80. 1 malignant (primary) neoplasm, unspecified. For example, if the patient was being treated for metastatic bone cancer, but the primary malignancy site is not documented, assign C79. 51, C80.
C61: Malignant neoplasm of prostate.
ICD-10 code: C79. 9 Secondary malignant neoplasm, site unspecified.
51 Secondary malignant neoplasm of bone.
I63. 9 - Cerebral infarction, unspecified | ICD-10-CM.
A malignant neoplasm (NEE-oh-plaz-um) is another term for a cancerous tumor. The term “neoplasm” refers to an abnormal growth of tissue. The term “malignant” means the tumor is cancerous and is likely to spread (metastasize) beyond its point of origin.
C80. 1 - Malignant (primary) neoplasm, unspecified | ICD-10-CM.
7 for Secondary malignant neoplasm of liver and intrahepatic bile duct is a medical classification as listed by WHO under the range - Malignant neoplasms .
ICD-10 code C43. 9 for Malignant melanoma of skin, unspecified is a medical classification as listed by WHO under the range - Malignant neoplasms .
When a primary malignancy has been previously excised or eradicated from its site and there is no further treatment directed to that site and there is no evidence of any existing primary malignancy at that site, a code from category Z85, Personal history of malignant neoplasm, should be used to indicate the former site ...
If the reconstruction were performed after the patient has completed all treatment for breast cancer, then you'd use Z85. 3 (personal history of breast cancer) as a third diagnosis code.
A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere.
Metastasis to digestive organs. Secondary malignant melanoma of pancreas. Secondary malignant melanoma of pancreas from eye. Secondary malignant neoplasm of esophagus. Secondary malignant neoplasm of gallbladder. Secondary malignant neoplasm of pancreas. Secondary malignant neoplasm of spleen.
A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere.
In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes. Primary malignant neoplasms overlapping site boundaries.
These guidelines, developed by the Centers for Medicare and Medicaid Services ( CMS) and the National Center for Health Statistics ( NCHS) are a set of rules developed to assist medical coders in assigning the appropriate codes. The guidelines are based on the coding and sequencing instructions from the Tabular List and the Alphabetic Index in ICD-10-CM.
Chapter 2 of the ICD-10-CM contains the codes for most benign and all malignant neoplasms. Certain benign neoplasms , such as prostatic adenomas, may be found in the specific body system chapters. To properly code a neoplasm, it is necessary to determine from the record if the neoplasm is benign, in-situ, malignant, or of uncertain histologic behavior. If malignant, any secondary ( metastatic) sites should also be determined.
When a primary malignancy has been previously excised or eradicated from its site and there is no further treatment directed to that site and there is no evidence of any existing primary malignancy at that site, a code from category Z85, Personal history of malignant neoplasm, should be used to indicate the former site of the malignancy. Any mention of extension, invasion, or metastasis to another site is coded as a secondary malignant neoplasm to that site. The secondary site may be the principal or first-listed with the Z85 code used as a secondary code.
A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion '), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous such as tumors in different quadrants of the same breast, codes for each site should be assigned.
Code C80.0, Disseminated malignant neoplasm, unspecified, is for use only in those cases where the patient has advanced metastatic disease and no known primary or secondary sites are specified. It should not be used in place of assigning codes for the primary site and all known secondary sites.
When a pregnant woman has a malignant neoplasm, a code from subcategory O9A.1 -, malignant neoplasm complicating pregnancy, childbirth, and the puerperium, should be sequenced first, followed by the appropriate code from Chapter 2 to indicate the type of neoplasm. Encounter for complication associated with a neoplasm.
There are also codes Z85.6, Personal history of leukemia, and Z85.79, Personal history of other malignant neoplasms of lymphoid, hematopoietic and related tissues. If the documentation is unclear as to whether the leukemia has achieved remission, the provider should be queried.
