Coding Correctly in 2023

The following information was provided by our coding advisor, Mary Suhr.

Key points:

  1. Time codes (when used) for inpatient visits have changed (see below). In 2023, when you share a service with an APP, you may bill on patient medical decision making or time spent.  You can add the time together and whoever spends more total time on that date of service (including face to face and non-face to-face) gets to be the service provider for that charge. 
  2. Extra time code: 99418 for every 15 minutes increments above average inpatient code.
  3. Observation codes are obsolete.
  4. Specific requirements for documentation of History and Physical exam are NOT needed for coding. Good documentation is still important part of medical practice and for liability; patient still needs to be examined.
  5. ALL outpatient and inpatient E/M visits will be leveled using the same methodology.
  6. Coding is based on medical decision making or time code (whichever has higher complexity). When selecting a level of service for Medical Decision Making, there is still the concept of having three components/tables and the requirement that two of the three components are met.  Tables 1, 2, and 3 outline the requirements.
  7. CPT 99251 (Straightforward Inpatient Consult) and CPT 99241 (Straightforward Outpatient Consult) are going away because the history and exam requirements for consults no longer apply and history/exam was the only difference between level 1 and level 2 consultation codes.
  8. For consultations, you still need a requesting provider, a reason for the consult and a report back to the provider.  CMS was explicit this year that assuming care of the problem is not considered a consult.
  9. Consultations cannot be shared between two providers (e.g. physicians and APPs).  If a consultation is shared between an APP and a MD, our advisor recommends the use admission codes for those.  This is true for inpatient consultations as well as office-based consultations.

Get Ready for 2021 Coding Changes

MDEdge GI Hep News: Prepare for major changes to E/M coding starting in 2021

New Evaluation and Management (E/M) codes are coming in 2021 –this could simplify documentation.

Here’s an excerpt:

1.Elimination of history and physical as elements for code selection

2. Choice of using medical decision making (MDM) or total time as the basis of E/M level documentation

  • MDM. While there will still be three MDM subcomponents (number/complexity of problems, data, and risk), extensive edits were made to the ways in which these elements are defined and tallied.
  • Time. The definition of time is now minimum time, not typical time or “face-to-face” time. Minimum time represents total physician/qualified health care professional time on the date of service

3. Modification of the criteria for MDM:

  • Terms. Removed ambiguous terms (e.g., “mild”) and defined previously ambiguous concepts (e.g., “acute or chronic illness with systemic symptoms”).
  • Definitions. Defined important terms, such as “independent historian.”
  • Data elements. Re-defined the data elements to move away from simply adding up tasks to focusing on how those tasks affect the management of the patient (e.g., independent interpretation of a test performed by another provider and/or discussion of test interpretation with another physician).

4. Modifier/add-on code): GPC1X can be reported with all levels of E/M office/outpatient codes in which care of a patient’s single, serious, or complex chronic condition is the focus. CMS plans to reimburse GPC1X at 0.33 RVUs (about $12).


“Contact your Electronic Health Records (EHR) vendor to confirm the system your practice uses will be ready to implement the new E/M coding and guidelines changes on Jan. 1, 2021.”

My take: The intent of these changes is logical.  The goal of coding is to align the reimbursement with the degree of effort and not simply allow pre-formatted templates justify upcoding.  They could lead to simplification of documentation and allow more documentation time for medical decision-making part of the visit.

Rising ER Costs & Changes in Billling Codes

USAToday: ‘Really astonishing’: Average cost of hospital ER visit surges 176% in a decade, report says

An excerpt:

The average emergency room visit cost $1,389 in 2017, up 176% over the decade. That is the cost of entry for emergency care; it does not include extra charges such as blood tests, IVs, drugs or other treatments…

In 2008, 17% of hospital visits were charged the most expensive code. That surged to 27% of visits in 2017, the report said. The average price for the most expensive code more than doubled from $754 in 2008 to $1,895 in 2017.

Hospitals also increased billings for the second most expensive code, but they billed the three least expensive codes less often compared to a decade ago.
