In their annual meeting to discuss changes to the Current Procedural Terminology (CPT), the American Medical Association (AMA) approved a set of proposed changes that will in all likelihood receive final approval in September 2021 and take effect on January 1, 2022.

In addition, for Radiology the anticipated changes will include further upgrades to the Category III codes that were initiated in 2021 (included below in 2021 Section). These new Category III codes were approved for early release which means that they will also take effect on July 1, 2021. Category III codes were intended to “enable more appropriate documentation and usage of new technologies.”

Proposed 2022 CPT Code Changes for Radiology

Category III Codes Set to Take Effect on July 1, 2021

Two new Category III codes have been established to report quantitative mp-MRI when used in the analysis of tissue composition, including multiparametric data acquisition, data preparation, and transmission, and interpretation/reporting. The two codes are 0648T and 0649T.

New Proposed Category I Codes to Take Effect on January 1, 2022

Four new diagnostic radiology codes have been proposed to report Trabecular Bone Score (TBS) to measure the structural condition in bone microarchitecture.

Two new codes have also been proposed to report thermal destruction of the intraosseous basivertebral nerve, a new procedure providing relief from chronic lower back pain.

The specific codes will accompany the final approval in the fall.

CPT Code Changes in Effect Since January 1, 2021

In addition, this legislation extends the “suspension of sequestration for Medicare fee-for-service payments by an additional three (3) months…adding on to the relief originally provided by the CARES Act.”

On September 1, 2020, the American Medical Association’s (AMA) Current Procedural Terminology (CPT) Editorial Panel approved changes to the CPT and HCPCS coding structure. Many of the new codes are being created as a result of bundling mandates or identified as potentially “misvalued” services. The changes were implemented on January 1, 2021.

As part of the annual mid-year review, the American College of Radiology (ACR) encourages radiology groups to implement new Category III codes. These new procedure codes affect irreversible electroporation (IRE) ablation and magnetic resonance spectroscopy (MRS).

Codes for Diagnostic Radiology for 2021

Screening CT of the Thorax

Codes 71250, 71260, 71270 are diagnostic. Also, a new CT of the thorax code will be available for reporting low-dose lung cancer screening.

The current HCPCS code G0297 was identified by the Centers for Medicare and Medicaid Services (CMS) as a high-value growth screen. It was subsequently referred to the editorial panel to establish a Category I CPT code to report low-dose CT for lung cancer screening.


Code 74425 – Diagnostic Radiology Procedures of the Urinary Tract will be revised, and a reciprocal parenthetical will be added clarifying that it can be reported with codes 50390, 50396, 50684, and 50690.

Fluoroscopic Guidance

Codes 64400-64450 and 64455 (Introduction/Injection of Anesthetic Agent and/or Steroid into the Somatic Nervous System) will be added in the inclusionary parenthetical notes following Codes 77002 and 77003 – Fluoroscopic Guidance.

Ultrasound Follow-up Study

Code 76970 – Other Diagnostic Ultrasound Procedure has been referred to the CPT Editorial Panel for deletion due to low volume.

Interventional Radiology

Percutaneous Core Needle Lung Biopsy

Code 32405 – Under Excision/Resection Procedures of the Lungs and Pleura will be deleted and replaced with a new code that bundles percutaneous core needle lung biopsy with imaging guidance when performed.

Specifically, Codes 32405 and 77012 were identified by the editorial panel as code pairs being performed together 75% or more of the time, and it was recommended that they are bundled.

Medical Physics

Medical Physics Dose Evaluation

There will be a new Category I code in Radiology, Diagnostic Radiology (Diagnostic Imaging), Other Procedures subsection of the CPT to report the assessment and calculation of radiation dose, and the potential adverse iatrogenic effects received by the patient that may require follow-up observation or treatment.

This will be a technical component only code since a medical physicist most often performs this actual service.

Evaluation and Management

Evaluation and Management (E/M) Visits

The editorial panel has approved significant revisions to the E/M code descriptors. In fact, this is the first major overhaul to E/M reporting in over 25 years.

These changes include:

  • Eliminating history and physical exam for code selection and reducing the administrative burden

  • Allowing physicians to choose between medical decision-making (MDM) or total time to determine E/M

  • Modifying MDM criteria to affect the management of a patient’s condition

Following the lead of the CMS’ overall initiative to reduce unnecessary documentation, these changes will:

  • Ensure payment levels for outpatient E/M visit codes are resource-based,

  • Minimize the need for audits, and

  • More accurately reflect the services provided

As part of the new E/M code structure, there will be a new add-on code created to report additional provider time in 15-minute increments. This new add-on code will be reported with codes 99205 and 99215. Other changes include:

  • New patient code 99201 will be deleted

  • New patient codes 99202, 99203, 99204, and 99205, and established patient codes 99211, 99212, 99213, 99214, and 99215 codes will be editorially revised

  • Prolonged services codes 99354, 99355, and 99356 will also be revised to reflect these changes.

According to the AMA, “history and/or physical examination as a component for code selection will be eliminated; code level selection will be based on medical decision making (MDM) or time. There will also be changes in the definition of MDM and time when used with these codes. The E/M guidelines will be revised extensively to reflect these changes.”

Category III

NOTE: These codes were available on July 1, 2020.

Irreversible Electroporation (IRE) Ablation

Two new proposed Category III codes will be available for reporting irreversible electroporation (IRE) ablation, a new procedure that uses high voltage electrical impulses to treat cancer.

Magnetic Resonance Spectroscopy (MRS)

Four new Category III codes will be available to report magnetic resonance spectroscopy (MRS) for the determination and localization of discogenic spine pain (cervical, thoracic, or lumbar).

Additionally, the September/October 2020 issue of the ACR Radiology Coding Source will outline the new 2021 codes and descriptors relevant to radiology groups and practices.


The final Medicare rule also included telehealth provisions, which are now in place permanently. The speed with which telehealth was adapted would have made it hard to roll back, and fortunately, it won’t be at this time.

An Finally….CDSM

Looking through the radiology lens, the Appropriate Use Criteria (AUC) program and CDSM were conceived as a process that would complement and elevate the referring provider’s diagnostic practice, strengthen the Medicare patient experience, and reduce needless advanced image testing. The requirement impacts all physicians, APP, and facilities billing Part B Services to Medicare.

With the education phase extended through 2021, CMS has an approved list of vendors, of which Infinx is a participating member, that can provide the advanced automation to process certificates of compliance for CDSM. Active participation will ensure payment from Medicare after the mandatory implementation date of January 1, 2022.

With radiology reimbursement under siege, it’s important to stay up to date on pending changes and ensure that your coding game, whether in-house or part of a third-party partnership, runs smoothly.
