ICD-10 Code C50.82 – Malignant neoplasm of overlapping sites of breast, male (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C50.82 – Malignant neoplasm of overlapping sites of breast, male
What it is
This code identifies a malignant breast tumor in a male when the cancer spans overlapping breast sites and no single site fully describes the lesion. Use it when documentation specifies overlapping involvement.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records note a breast mass, skin or nipple changes, or imaging and biopsy findings confirming malignancy in overlapping breast regions.
When to use this code
Use this code when the provider documents primary breast cancer in a male and states that the tumor involves overlapping sites of the breast. It is appropriate when the record does not support a more specific anatomic site code. Check documentation if laterality or exact site is unclear.
Do not use for
Do not use it for benign breast disease, unspecified breast cancer site, or metastatic disease to the breast. If the record names a single breast subsite, code that more specific location instead.
Coding tip
Verify that “overlapping sites” is explicitly documented before assigning C50.82.
