What 70015 covers

This service covers radiological supervision and interpretation of contrast cisternography, an imaging study that follows intrathecal contrast through cerebrospinal fluid spaces. A radiologist interprets the images to assess CSF pathways, including when a leak is suspected. The study is typically performed in a hospital or imaging department after contrast has been introduced into the spinal fluid; the clinician administering it may be different from the interpreting radiologist.

Select this code for the contrast cisternography study, not simply for a spinal puncture or a radionuclide CSF-flow study. The report should identify the study and document the radiologist’s interpretation and findings. CMS recognizes separately priced professional and technical components: report modifier 26 for the interpretation, modifier TC for the equipment and staff, or neither modifier when billing the global service. The technical service includes the imaging resources and personnel; the professional service is the interpretation.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

78630CSF scan
Use 70015 for contrast cisternography; use 78630 when the study uses a radiopharmaceutical.
62270Lumbar puncture
62270 represents a diagnostic spinal puncture without imaging guidance, not the radiologist’s cisternography interpretation.
62328Lumbar puncture
62328 represents a diagnostic lumbar puncture performed with imaging guidance; 70015 represents the contrast cisternography imaging service and interpretation.

70015 billing questions

How is this different from radionuclide cisternography?

This code is for contrast cisternography. Code 78630 is used for cisternography performed with a radiopharmaceutical.

Which modifier identifies the radiologist’s interpretation?

Use modifier 26 for the professional component, which represents the interpretation.

When is modifier TC appropriate?

Use TC for the technical component, representing the equipment and staff. Bill without 26 or TC for the global service.

Can the spinal puncture be reported separately?

A separately performed diagnostic lumbar puncture to administer the intrathecal contrast may be reported under the applicable puncture code. The cisternography code represents the imaging service and interpretation.

What documentation supports reporting this code?

Document that contrast cisternography was performed and include the radiologist’s interpretation of the images and relevant findings, such as assessment of CSF pathways or a suspected leak.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
