Top 15 lung cancer diagnoses

Lung cancer is among the most common types of cancer in the U.S.

More than 540,000 living Americans had a lung cancer diagnosis during their lives, and there are nearly 237,000 new cases estimated for 2022. Advancements in early detection, additional treatment options, and people quitting smoking are helping to decrease cases.

Patients visit multiple specialists during cancer treatment, including oncologists and radiologists. Each encounter with a healthcare provider includes the patient’s primary diagnosis on the healthcare insurance claim, which results in the number of primary diagnosis claims being greater than the number of patients living with or newly diagnosed with cancer.

Using data from the Definitive Healthcare ClaimsMx product, we analyzed lung cancer ICD-10 codes to find the highest number of primary diagnoses for calendar year 2021.
