CPT Code Resequencing

I don't believe CPT's resequencing initative altered any codes that are used for EDX studies. Here is a short summary in case members encounter it in other aspects of their practice.

Instead of deleting and renumbering codes in order to display related codes together, resequencing allows adjacent placement of related concepts in the codebook regardless of the availability of code numbers for numerical placement. This change allows for greater code continuity over time and creates more options for future growth and flexibility of content.

Resequenced codes are noted with a # symbol in their new, out-of-sequence location. References have been placed numerically throughout the codebook at codes' previous locations that direct users to the out-of-sequence code. Appendix N also contains a list of resequenced codes.

CPT Publishes Guidance for Consultation Coding

CPT just released an informational memo addressing consultation services and transfer of care. Much of the memo will not apply for Medicare patients since CMS is no longer accepting consultation codes. The memo suggests that Medicare contractor websites are the best place to locate further coding inforamtion for Medicare patients.

Unfortunately, a lack of direction from CMS to contractors has resulted different solutions for reporting low-level inpatient consultations. Until more specific guidance from CMS is given, adhere to the key elements of the service provided when selecting the appropriate code. For example, level 3 inpatient consultation (99253) requires detailed history, detailed exam, and low complexity decision making. This matches exactly with level 1 inpatient hospital care (99221), which requires detailed history, detailed exam, and low complexity decision making.

New CPT® Header for NCS Codes

During discussion of how tests performed with preconfigured electrode arrays should be reported, the AANEM and others agreed it would be helpful to separately identify and define nerve conduction tests in the 2010 CPT® codebook.  A new header for "Nerve Conduction Tests" was added to complement the addition of 95905. Nerve conduction studies (NCSs) previously did not have their own introductory language.  The new header provides the following introductory information:

The following applies to nerve conduction tests (95900-95904): Codes 95900-95904 describe nerve conduction tests when performed with individually placed stimulating, recording, and ground electrodes. The stimulating, recording, and ground electrode placement and the test design must be individualized to the patient’s unique anatomy. Nerves tested must be limited to the specific nerves and conduction studies needed for the particular clinical question being investigated. The stimulating electrode must be placed directly over the nerve to be tested, and stimulation parameters properly adjusted to avoid stimulating other nerves or nerve branches. In most motor nerve conduction studies, and in some sensory nerve conduction studies, both proximal and distal stimulation will be used. Motor nerve conduction study recordings must be made from electrodes placed directly over the motor point of the specific muscle to be tested. Sensory nerve conduction study recordings must be made from electrodes placed directly over the specific nerve to be tested. Waveforms must be reviewed on site in real time, and the technique (stimulus site, recording site, ground site, filter settings) must be adjusted, as appropriate, as the test proceeds in order to minimize artifact, and to minimize the chances of unintended stimulation of adjacent nerves and the unintended recording from adjacent muscles or nerves. Reports must be prepared on site by the examiner, and consist of the work product of the interpretation of numerous test results, using well-established techniques to assess the amplitude, latency, and configuration of waveforms elicited by stimulation at each site of each nerve tested. This includes the calculation of nerve conduction velocities, sometimes including specialized F-wave indices, along with comparison to normal values, summarization of clinical and electrodiagnostic data, and physician or other qualified health care professional interpretation.

Code 95905 describes nerve conduction tests when performed with preconfigured electrodes customized to a specific anatomic site.

Addition of this comprehensive definition will help physicians, coders, and payors to determine the appropriate code to report physician work. This definition clarifies several important points. (1) Testing should be limited to those nerves necessary to address the clinical question being investigated; standardized, screening tests are not the same as carefully designed NCSs and do not entail the same physician work. (2) Waveforms must be reviewed on site. (3) Reports must be prepared on site.

New CPT® Code to Report Preconfigured Electrode Array Nerve Conduction

Opening the 2010 CPT® codebook for the first time last week, I was pleased to see the final publication of new code 95905. This new code will be used to report nerve conduction tests performed using preconfigured electrode arrays. Use of preconfigured arrays and highly automated devices has been a controversial issue between EDX specialists and primary care physicians for years. The AANEM and a number of other specialty societies spent long and difficult hours working to develop a coding solution that correctly describes this new and different service. The addition of 95905 appropriately distinguishes the new service from traditional NCSs.

Physicians who perform nerve conduction testing with preconfigured electrode arrays should now report code 95905: “Motor and/or sensory nerve conduction, using preconfigured electrode array(s), amplitude and latency/velocity study, each limb, includes F-wave study when performed, with interpretation and report.” Parenthetical instructions further direct that, by definition, 95905 should be reported once per limb, and that 95905 should not be reported in conjunction with 95900-95904 or 95934-95936.

Members are encouraged to share this coding memo with colleagues and coders to facilitate correct use of the new code. You can print, save, or link to the memo here.

H1N1 CPT Code

With both seasonal influenza and H1N1 influenza circulating this flu season, the AMA announced this week it has expedited the publication of a new code specific to vaccine administration and revised existing code 90663 to include the H1N1 vaccine. The new Current Procedural Terminology (CPT®) code issued by the AMA will streamline the reporting and reimbursement procedure for physicians and health care providers who are expected to administer nearly 200 million doses of the H1N1 vaccine in the United States. In consultation with the U.S. Department of Health and Human Services, the AMA CPT® Editorial Panel created code 90470 to report H1N1 immunization administration and counseling. Code 90663 was revised by the CPT® Editorial Panel to refer specifically to the H1N1 vaccine product. Both are effective immediately.
