Code: C78.7

Code Name: ICD-10 Code for

Block: Secondary malignant neoplasm of liver and intrahepatic bile duct


Excludes1: secondary carcinoid tumors of liver (C7B.02)
secondary carcinoid tumors of peritoneum (C7B.04)

Excludes2: lymph node metastases (C77.0)

Details: Malignant neoplasms of ill-defined, other secondary and unspecified sites (C76-C80)

Guidelines: Neoplasms (C00-D49)

Note: Functional activity

All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
Morphology [Histology]
Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. 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
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.
Malignant neoplasm of ectopic tissue
Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Hey everyone, just out of curiosity what are you using for bilateral foot pain and bilateral metatarsalgia? I know the specificity is for example M79.671 for the right foot and M79.672 for the left on the pain diagnosis, however does anyone know of the bilateral code as it is not listed in the coding books? Furthermore, when a doctor refers to these diagnosis' in the patient chart we're being told by our EHR provider that the coder is to be defaulting the code to the right foot to cover bilateral billing. Is this a common practice that I should be doing? Thank you all for your help.
