In simple words: This code means the person has genes that make them more likely to get cancer. If they already have cancer, that should be the main diagnosis. This code is used to show the increased risk because of their genes.

This ICD-10-CM code signifies a genetic predisposition to developing malignant neoplasms (cancers).It indicates an increased risk due to inherited genetic factors.If a patient has a current malignant neoplasm, that diagnosis (C00-C75, C81-C96) should be coded first.Additionally, if applicable, a code for personal history of malignant neoplasm (Z85.-) should be used as a secondary code.

Example 1: A patient with a family history of breast cancer undergoes genetic testing which reveals a BRCA1 mutation.This increases her risk of developing breast cancer.The code Z15.0 would be used in conjunction with a code indicating the genetic testing itself (if there is such a code)., A 45-year-old male with a strong family history of colon cancer is found to have a Lynch syndrome gene mutation. This code would be documented along with counseling on colon cancer screening and surveillance., A patient presents for genetic counseling after a relative is diagnosed with a particular type of leukemia. The genetic testing reveals that this patient is also at higher than average risk. This code would be applicable in this context.

Genetic test results showing the specific gene mutation, family history of malignant neoplasms, and documentation of genetic counseling sessions.

** This code is primarily used for risk assessment and preventative care planning.It's crucial to document the specific gene mutation and the associated risk level to ensure appropriate coding.
