Laser Interstitial Thermal Therapy (LITT)
Laser interstitial thermal therapy was deleted from the Radiation Therapy Section (D) in ICD-10-PCS in FY 2023. It has been re-classified to the Medical/Surgical Section (0) since, technically, it is ‘thermal therapy,’ not ‘radiation therapy.’ These codes have been re-classified in the MS-DRG system according to their body system. LITT uses laser probe-generated heat to destroy soft tissue at targeted sites. Used to treat tumors in places that are hard to reach with conventional surgery.
What is LITT
Laser interstitial thermal therapy (LITT) is a minimally invasive surgical technique that uses a small laser to destroy unhealthy brain tissue. It can be an effective treatment option for recurrent brain tumors, radiation necrosis, and tumors that form deep within the brain. It is also used to treat certain types of epilepsy.
