Gastroenterology Coding Alert

Get a grip on updated descriptions and expert advice on using MDM versus time.

January 1 is not that far off, but you can start preparing now for the 2023 evaluation and management (E/M) service code changes that are coming. You’ll need to adopt the same medical decision making (MDM) and time changes for other E/M services as the ones CPT^® introduced in 2021 for 99202-99205/99211-99215 office/outpatient E/M services. Among the categories to which guideline, headline, and code revisions will apply on Jan. 1, 2023, are the office/outpatient consultation codes.

Stick around for valuable information on the 2023 office/outpatient consultation E/M code revisions, deletions, and additions in this two-part series. Then, stay tuned to future issues of Gastroenterology Coding Alert for coverage of the E/M changes in other categories.

Add 2021 E/M Rules to Consultations in 2023

The changes begin with revisions to the consultation CPT^® guidelines, including adding “other qualified healthcare professional” to the providers who will be able to perform consultations as well as start diagnostic or therapeutic services during the visit or at a subsequent visit.

CPT^® has also revised the places of service where consultations can take place in the 2023 code set:

• CY 2022: “…report consultations provided in the office or in an outpatient or other ambulatory facility, including hospital observation services, home services, domiciliary, rest home, or emergency department.”
• CY 2023: “…report consultations that are provided in the office or other outpatient site, including the home or residence, or emergency department.”

Mandatory modifier: The guidelines also state that you should append modifier 32 (Mandated services) to a consultation that is required. For example, if a payer requests a consultation, such as a second opinion before the payer approves treatment, you should append modifier 32 to the applicable consultation code.

Know the Revised Office/Outpatient Consultation Codes

CPT^® has also updated the office/outpatient consultation codes to allow the provider to select the level visit based on MDM or time when applicable.

The revised office/outpatient consultation E/M codes for CY 2023 are as follows (Note: Portions of the revised descriptors are emphasized for easy reference):

• 99242 (Office or other outpatient consultation for a new or established patient, which requires a medically appropriate history and/or examination and straight­forward medical decision making. When using total time on the date of the encounter for code selection, 20 minutes must be met or exceeded.)
• 99243 (Office or other outpatient consultation for a new or established patient, which requires a medically appropriate history and/or examination and low level of medical decision making. When using total time on the date of the encounter for code selection, 30 minutes must be met or exceeded.)
• 99244 (Office or other outpatient consultation for a new or established patient, which requires a medically appropriate history and/or examination and moderate level of medical decision making. When using total time on the date of the encounter for code selection, 40 minutes must be met or exceeded.)
• 99245 (Office or other outpatient consultation for a new or established patient, which requires a medically appropriate history and/or examination and high level of medical decision making. When using total time on the date of the encounter for code selection, 55 minutes must be met or exceeded.)

Add on this prolonged service code: CPT^® 2023 also adds a parenthetical note to 99245 instructing you to use prolonged services add-on code +99417 (Prolonged outpatient evaluation and management service(s) time with or without direct patient contact beyond the required time of the primary service when the primary service level has been selected using total time, each 15 minutes of total time (List separately in addition to the code of the outpatient Evaluation and Management service)) for services lasting 70 minutes or longer.

If you’re billing an office/outpatient consultation E/M visit solely on the basis of time, you can assign +99417 only after 15 minutes have elapsed beyond the initial 55 minutes of the 99245 consultation — in other words, after the service has exceeded 70 minutes total time. Additionally, the 15 minutes of +99417 may count whether the provider was in direct contact with the patient or not.

Key code deletion: CPT^® 2023 deletes 99241 (Office consultation for a new or established patient, which requires these 3 key components: A problem focused history; A problem focused examination; and Straightforward medical decision making…). Instead, you’ll report 99242 for a consultation that involves straightforward MDM.

Understand How to Choose the Correct Consultation Code

“As part of the 2023 revisions, this range of consultation codes can be documented through either time or MDM. History and exam, as with office visits, are no longer key components of consultations,” says Nancy Clark, CPC, COC, CPB, CPMA, CPC-I, COPC, AAPC Fellow, senior manager at Eisner Advisory Group LLC in Iselin, New Jersey.
