Denosumab is covered for cancer treatment–induced bone loss (CTIBL) in patients with breast cancer receiving adjuvant aromatase inhibitors (AI) or in patients with nonmetastatic prostate cancer receiving androgen deprivation therapy (ADT) when documentation supports the cancer diagnosis and therapy.
Denosumab is covered for treatment of bone metastasis from a solid tumor when the claim lists bone metastasis (ICD-10-CM C79.51) as the primary diagnosis and the original cancer or history of cancer is included as the secondary diagnosis.
