Z85.83 Personal history of malignant neoplasm of bone and soft tissue

ICD-10-CM Code Z85.83: Personal history of malignant neoplasm of bone and soft tissue

ICD-10-CM code Z85.83 represents the personal history of a malignant neoplasm of bone and soft tissue. The source material identifies this as a supplemental code, distinguishing it from active reportable diagnoses. It exists within a hierarchy that includes more specific subcodes for the history of bone neoplasms and soft tissue neoplasms. The underlying clinical conditions involve rare solid tumors of mesenchymal origin. 1 3

Plain-language overview

The provided coding source identifies Z85.83 as the supplemental code for the personal history of a malignant neoplasm of bone and soft tissue. This code serves to document a patient's past occurrence of these specific types of tumors. 3

What this code represents

The coding source lists Z85.83 as a supplemental code, distinguishing it from reportable active malignant neoplasms like C49.0. This classification indicates that Z85.83 is utilized for personal history tracking rather than representing a current primary disease. 3

Coding details

The coding source lists Z85.830 for the personal history of malignant neoplasm of bone and Z85.831 for the personal history of malignant neoplasm of soft tissue. These codes appear as supplemental subcategories under the broader Z85.83 code. 3

Clinical context

Sarcomas are a heterogeneous group of rare solid tumors of mesenchymal cell origin divided into sarcomas of soft tissues and sarcomas of bone. The provided clinical sources describe these underlying malignant neoplasms without explicitly linking them to the Z85.83 history code. 1 2

Documentation considerations

The coding source lists Z85.830 for a history of bone neoplasms and Z85.831 for a history of soft tissue neoplasms. The provided excerpts do not establish specific documentation rules regarding how to select between these subcodes. 3

What the sources add

The clinical sources describe malignant bone and soft tissue lesions as rare pathologies involving mesenchymal tissues, while the coding source provides the specific supplemental history codes. Comparing these domains shows the clinical conditions are tracked using the Z85.83 code family. 1 2 3

Questions to verify

The provided coding source lists Z85.83 and its subcodes but does not mention any reviewer verification processes. The excerpts do not establish criteria for choosing between the parent code and the more specific subcodes. 3
