Is 72170 bundled with 73520

Yes, CPT code 72170 (MRI, lumbar spine) is typically bundled with CPT code 73520 (X-ray, pelvis) when performed together, meaning they are often billed as a single service. The bundling occurs because the MRI and X-ray procedures are related and may be used to evaluate the same condition. However, specific billing practices can vary, so it's important to check payer guidelines for any exceptions.
