In the case of
CPT code 76942 (Ultrasonic guidance for needle placement (for example, biopsy, aspiration, injection, localization device), imaging supervision and interpretation), we agreed with the AMA RUC’s recommendation to replace the current equipment input of the
“room, ultrasound, general” (EL015) with “ultrasound unit, portable” (EQ250). We note that this service is typically reported with other codes that describe the needle placement procedures and that the recommended change in equipment from a room to a portable device reflects a change in the typical kinds of procedures reported with this image guidance service. Given this change, we believe that it is appropriate to reconsider the procedure time assumption currently used in establishing the direct PE inputs for this code, which is 45 minutes. We reviewed the services reported with CPT code 76942 to identify the most common procedures furnished with this image guidance. The code most frequently reported with CPT code 76942 is CPT 20610 (Arthrocentesis, aspiration and/or injection; major joint or bursa (for example, shoulder, hip, knee joint, subacromial bursa). The assumed procedure time for this service is five minutes. The procedure time assumptions for the vast majority of other procedures frequently reported with CPT code 76942 range from 5 to 20 minutes. Therefore, in addition to proposing the recommended change in equipment inputs associated with the code, we proposed to change the procedure time assumption used in establishing direct PE
inputs for the service from 45 to 10
minutes, based on our analysis of 30 needle placement procedures most frequently reported with CPT code 76942. We noted that this reduced the clinical labor and equipment minutes associated with the code from
58 to 23 minutes.
Comment: Several commenters noted that the AMA RUC is planning to conduct surveys and review the assumptions regarding the code and that CMS will be in a better position to make more accurate determinations if it waits for that data from the AMA RUC. One commenter stated that CMS should not make a change in the direct PE input database based on information in the Medicare claims data without input from the medical specialty societies whose members furnish and report the ultrasound guidance as described with CPT code 76942 and that a recommendation from the AMA RUC may provide better data than the information contained on Medicare claims.
Response: We appreciate the partnership of the AMA RUC in the misvalued code initiative, but as a general principle, we do not believe that we should refrain from making appropriate changes to code values solely because the AMA RUC is planning to review a service in the future. In some cases, we believe that we should examine claims information and other sources of data and make proposals regarding the appropriate inputs used to develop the amount Medicare pays for PFS services. We believe that notice and comment rulemaking itself provides a means for the public, including medical specialty societies and the AMA RUC, to respond substantively to proposed changes in resource inputs for particular services. Furthermore, in cases like this one, we do not believe that the information reflected in the Medicare claims data is subjective or open to differing interpretations.
Comment: Several commenters, including the AMA RUC, pointed out that CPT code 76942 includes supervision and interpretation, which represents both time and work that is
CMS-1600-FC 91
separate from the surgical code and that the additional time included in the direct PE inputs may reflect time in addition to the base procedure.
Response: We appreciate the response of the AMA RUC and others in pointing out concerns with our assumptions.
We note that the proposed clinical labor service period of 23 minutes includes the 10 minutes of intra-service time in addition to 2 minutes for preparing the room, equipment, and supplies, 3 minutes for preparing and positioning the patient, 3 minutes for cleaning the room, and 5 minutes for processing images, completing data sheet, and presenting images and data to the interpreting physician. We did not receive information from any commenters suggesting that the time allocated for these tasks was inadequate. Therefore, we are finalizing our adjustment to the clinical labor minutes associated with this code, as proposed.
