Important Update: The DWC adopted an MUE limiting the number of units of G2212 providers may bill. Details below!
This year, California’s Division of Workers’ Compensation (DWC) debuted a new code for billing extended Evaluation and Management (E/M) time: Healthcare Common Procedure Coding System (HCPCS) G2212. Correctly applying G2212, and navigating new rules for E/M billing generally, has been a challenge for many provider offices.
DaisyBill is here to help! Below is a breakdown of exactly how to use G2212 correctly to ensure your office receives prompt, accurate reimbursement.
The DWC made a major change to E/M billing effective March 1, 2021. Previously, providers determined the E/M service level using a complex system of E/M service components. This year, the DWC scrapped that system in favor of a more streamlined, two-pronged approach. For all dates of service on or after March 1, providers determine the E/M service level via:
For a thorough explanation of this change (and details regarding MDM), see our recent detailed post on the subject. This post will focus on time-based billing only. For dates of service on or after March 1, providers simply choose the Current Procedural Terminology (CPT) code that corresponds to the time spent on E/M services.
E/M services include:
The table below displays the appropriate codes by time, for new and established patients, when NO extended E/M service time is applicable.
The table below demonstrates that the E/M CPT codes can only accommodate a maximum of 74 minutes (for new patients) and 54 minutes (for established patients). When E/M services exceed either of those limits, and the provider chooses to bill by time, the provider must use G2212.

For a handy guide to applying G2212, continue reading.
To correctly apply G2212, for every 15 minutes of E/M services time beyond the maximum allotted by CPT 99205 (74 minutes) or CPT 99215 (54 minutes), a provider must report one (1) unit of G2212.
When applying G2212, providers must adhere to the following rules:
In practice, billing G2212 works as shown in the table below, per the CMS Manual System. For example, 89 to 103 minutes of total E/M services in a single encounter for a new patient qualifies for one unit of 99205, plus one unit of G2212:

*Total E/M Services Time is the sum of all time, including prolonged/extended time, spent by the reporting practitioner on the date of service of the visit.
California workers’ comp providers must use HCPCS G2212 to bill for extended E/M services time. This requirement stems from a disagreement between the American Medical Association (AMA) and the Centers for Medicare and Medicaid Services (CMS).
The AMA developed CPT 99417 for billing extended E/M service time. However, the California DWC did not adopt CPT 99417. Instead, the DWC followed the lead of the CMS, which objected to CPT 99417 as written. According to the CMS:
The California DWC concurred, and adopted HCPCS G2212 for workers’ comp in lieu of CPT 99417. But in their attempt to avoid “potential inconsistency,” the CMS created exactly the kind of “potential confusion” currently furrowing the brows of California providers.
