C40.02 Malignant neoplasm of scapula and long bones of left upper limb

ICD-10-CM Code C40.02: Malignant neoplasm of scapula and long bones of left upper limb

ICD-10-CM code C40.02 identifies a malignant neoplasm involving the scapula and long bones of the left upper limb. This diagnosis concept is mapped in standard coding references and cancer surveillance lists. Clinical literature notes that malignant bone tumors of the upper limb demand high clinical suspicion, with osteosarcoma accounting for the majority of such malignant presentations. 3 5 1

Plain-language overview

Code C40.02 denotes a malignant neoplasm of the scapula and long bones of the left upper limb, providing a specific diagnostic label for this particular type of cancer. [S3] 3

What this code represents

Within the ICD-10-CM casefinding list, C40.02 is a specific billable code nested under the broader category C40.0 for malignant neoplasms of the scapula and long bones of the upper limb. [S3] 3

Code C40.02 distinguishes the left upper limb from the right upper limb (C40.01) and the unspecified upper limb (C40.00), establishing laterality as a defining feature of this specific diagnosis. [S3] 3

Clinical context

Clinical literature indicates that osteosarcoma accounts for the majority of malignant bone tumor presentations in the upper extremity, which includes the humerus, radius, and ulna. [S1] 1

Malignant bone tumors in the upper limbs of children, such as osteosarcoma or Ewing sarcoma, are rare but demand high clinical suspicion according to clinical source data. [S1] 1

Documentation considerations

Diagnostic documentation for malignant limb bone tumors like osteosarcoma relies on a combination of clinical, imaging, and pathological examination to establish the diagnosis. [S2] 2

Coverage and utilization context

Code C40.02 appears in a Centers for Medicare and Medicaid Services article concerning genomic sequence analysis panels in the treatment of solid organ neoplasms, but the source does not state any coverage conclusions regarding specific services or treatments. [S4] 4

What the sources add

A comparison of sources shows that cancer surveillance and terminology references establish C40.02 as a valid ICD-10-CM diagnosis code, while clinical literature describes the biological behavior and diagnostic approach for the underlying malignant bone tumors. [S3, 3 5 1 2

The National Cancer Institute's EVS Explore platform maps C40.02 to the SNOMEDCTUS concept identifier 460281000124102, providing a cross-system terminology link for this diagnosis. [S5] [5](https://evsexplore.semantics.cancer.gov/evsexplore/concept/snomedctus/460281000124102)
