The CPT® [i] manual for 2018 contains 314 code changes, including 172 new codes and 60 revised codes. In addition, 82 codes were deleted and two new modifiers were added. This article will describe the highlights of those changes, based on their adoption by the Centers for Medicare and Medicaid Services (CMS) for use in the Medicare program. Commercial payers may differ from Medicare in their adoption of coding changes, and so practices are advised to monitor their claims denials in the early part of 2018 to be sure any modified codes are being accepted and paid by all carriers.
Quite a few of the 2018 CPT code revisions pertain to radiology [ii] and are covered in our companion article How the 2018 Coding Changes Will Affect Radiology Practices. We will not repeat those here, but let’s investigate the other changes for 2018
Evaluation and Management (E&M)
Almost every medical practice uses E&M codes and the most common of them have not been changed. However, there are 5 new codes for Behavioral Health and Cognitive Assessment services. Here’s the crosswalk of those codes from 2017 to 2018:
|HCPCS Code for 2017||CPT Code for 2018||Description|
|G0505||99483||Assessment of and care planning for a patient with cognitive impairment, requiring an independent historian.|
|G0502||99492||Initial psychiatric collaborative care management
|G0503||99493||Subsequent psychiatric collaborative care management
|Initial or Subsequent psychiatric collaborative care management
|G0507||99484||Care Management services for behavioral health conditions
Four Observation Codes (99217-99220) have been revised to specify that they are to be used in the Outpatient Hospital location.
Wound reconstruction codes were modified as follows:
- CPT 15730 has been added to describe Midface skin flap reconstruction (i.e., zygomaticofacial flap) with preservation of vascular pedicle(s).
- CPT 15733 replaces 15732 for Muscle, myocutaneous or fasciocutaneous flap and adds buccinators and genioglossus to the muscles previously described.
CPT 17250 Chemical cauterization of granulation tissue now includes only proud flesh, deleting sinus or fistula from the description.
Mastectomy codes 19301 and 19302 will have the following available add-on code:
CPT 19294 Preparation of tumor cavity, with placement of a radiation therapy applicator for intraoperative radiation therapy (IORT) concurrent with partial mastectomy.
There are 5 new codes and 3 revised codes related to Nasal Sinus Endoscopy:
|CPT Code||Differential Description|

|Nasal/sinus endoscopy, surgical with ethmoidectomy; total (anterior and posterior)|
|With frontal sinus exploration, including removal of tissue from frontal sinus, when performed. Previously worded with or without removal of tissue from frontal sinus.|
The coding for Total Heart Replacement now uses Category I codes that replace similar Category III codes. Note that the new descriptions do not match up exactly with those that were replaced.
|Code for 2017||Code for 2018||Description|
|0051T||33927||Implantation of a total replacement heart system (artificial heart) with recipient cardiectomy|

Both the male and female genital systems incurred new, revised and deleted procedure codes, as follows:

Pathology and Laboratory
The majority of the 41 new pathology codes are new genetic testing codes. Many of the new codes were previously bundled into a single molecular pathology procedure.
There are two new Zika virus test codes, 86794 (Zika virus, IgM) and 87662 (Zika virus, amplified probe technique), along with some changes to the family of drug screen codes.
A total of 12 Pathology and Laboratory codes were deleted, encompassing a variety of procedural areas.
The Medicine section underwent numerous code revisions in the areas of:

* Medicare payment was effective for 2017, but the code was not previously listed in the CPT book.
New codes were also added for the following procedures and services:
|94617||Exercise test for bronchospasm, including pre- and post-spirometry, electrocardiographic recording(s), and pulse oximetry|

|97127||Therapeutic interventions that focus on cognitive function (e.g., attention, memory, reasoning, executive function, problem solving, and/or pragmatic functioning) and compensatory strategies to manage the performance of an activity (e.g., managing time or schedules, initiating, organizing and sequencing tasks), direct (one-on-one) patient contact|
|97763||Orthotic(s)/prosthetic(s) management and/or training, upper extremity(ies), lower extremity(ies), and/or trunk, subsequent orthotic(s)/prosthetic(s) encounter, each 15 minutes|
Two medicine codes, related to Development of Cognitive Skills (97532) and Orthotic/Prosthetic Training (97762), were deleted.
As noted at the outset, claims denials should be monitored carefully early in 2018 to be sure any coding revisions made by the practice are being processed correctly by Medicare and commercial payers. It is quite possible that different codes will be required to describe the same procedure, depending on the acceptance of coding changes by the various payers.
The overall effect of coding changes is influenced by the volume of each code’s usage in a particular practice, and by the value assigned to the codes by the payers. This is especially true where revisions have resulted in the bundling of payment under a single code that previously was reported using several separate codes. A volume-weighted analysis based on the preceding year’s activity will generally give a good estimation of the effects of the CPT code changes we have described.
