About 95961: Cortical and subcortical brain mapping
Reports functional brain mapping by stimulation and recording to identify important cortical or subcortical areas during procedures such as epilepsy surgery.
This service maps brain function by stimulating and/or recording from cortical and subcortical areas, helping the surgical team identify regions involved in functions such as language or movement. It is commonly performed during neurosurgery, including epilepsy surgery, by a qualified physician or other health care professional working with the operating team. Mapping may take place in the operating room or another location.
Select the code based on the mapping service and the physician or qualified professional’s time. The record should support the clinical purpose, stimulation or recording performed, findings relevant to the surgical plan, and time spent. CMS recognizes professional and technical components: report modifier 26 for the interpretation, TC for equipment and staff, or neither modifier for the global service. The professional and technical components are separately priced when billed with their respective modifiers.
CMS billing rules for 95961

95961 billing questions
How is brain mapping different from somatosensory evoked-potential testing?
Brain mapping uses stimulation and/or recording to identify functional cortical or subcortical areas. Somatosensory evoked-potential testing evaluates responses along sensory pathways.
What documentation supports reporting this service?
Document the reason for mapping, the stimulation or recording performed, relevant responses and findings, and the physician or qualified professional’s time.
When should modifier 26 or TC be reported?
Use modifier 26 for the professional interpretation and TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
Can this service be reported with motor or sensory evoked-potential testing?
It may be reported in the same operative case when those tests are separately performed. The record should distinguish the mapping service from the evoked-potential testing.
What is the distinction between this code and 95962?
95961 reports the initial brain-mapping service. 95962 is the related code for additional mapping time.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
