Dermatology imaging
About 96931: Reflectance confocal microscopy, first lesion
Reports reflectance confocal microscopy image acquisition and interpretation for the first skin lesion evaluated during the service.
Reflectance confocal microscopy (RCM) uses noninvasive optical imaging to examine skin structures at a cellular level. Dermatology practices may use it to evaluate a suspicious lesion, such as when assessing features that can help distinguish benign from malignant change. The service produces images of the lesion without removing tissue for a conventional biopsy. A dermatologist or other qualified clinician interprets the images and documents the findings.
Report 96931 for the first lesion when the service includes both image acquisition and interpretation with a report. Documentation should identify the lesion examined, support the clinical reason for imaging, and include the acquired images and interpretation. This is the global-test code: when acquisition and interpretation are performed and reported separately, use the corresponding component codes rather than reporting 96931 for the same work. For additional lesions, select the applicable additional-lesion code based on whether both components or only one component was performed.

96931 billing questions
When should 96931 be reported instead of 96932 or 96933?
Use 96931 when both RCM image acquisition and interpretation with a report are performed for the first lesion. Codes 96932 and 96933 describe acquisition only and interpretation/report only, respectively, for that first lesion.
Can 96931 be reported with its component codes for the same lesion?
Do not report the global service together with separate component codes for the same work. Use the component codes when acquisition and interpretation are separately performed and reported.
How is an additional lesion reported?
Use the additional-lesion code that matches the work performed: 96934 for acquisition and interpretation, 96935 for acquisition only, or 96936 for interpretation and report only.
What documentation supports 96931?
Document the lesion examined, the reason for RCM, image acquisition, and the clinician’s interpretation and report. The record should make clear that both components were completed for the first lesion.
Does 96931 describe a skin biopsy?
No. It describes noninvasive reflectance confocal imaging and interpretation; tissue removal for histopathologic examination is a different service.
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.
