Modifier 52 vs. 53
December 29th, 2015 - Seth Canterbury, CPC, ACS-EM
So you’ve read the descriptions for both Modifiers 52 and 53, but you’re still on the fence as to which one is appropriate for a certain surgical case. This brief article will try to better differentiate between these two often-confused modifiers.
Modifier 53 is appropriate when a procedure is discontinued due to “an extenuating circumstance or one that threatens the well-being of the patient,” and this physician decision always happens after the procedure has begun in cases where Modifier 53 is appropriate. Often times the decision is made so early in the procedure that only an initial incision has been made but no specific work (as stated in the description of the code that was to have been used) has been accomplished. A re-scheduling of the entire procedure will often be necessary once the reason for the termination is evaluated and resolved, as the original reason for the surgery still exists and still needs surgical treatment.
Modifier 52 is used when a physician elects to partially reduce or eliminate a procedure, often (but not always) making this decision before the procedure has even begun. However, something (usually the majority of the work included in the description of the code) is still accomplished in situations where Modifier 52 is appropriate. In some cases, performance of the “reduced” or “eliminated” portion may be done at a later surgery. In other cases, this omitted portion of the service will not be performed at a subsequent operation. Performance of the omitted portion may not be possible because the structure is no longer present (was previously excised) or it is not simply not medically necessary to do this portion of the service.
Here’s where it can get a bit confusing: It is possible that a decision could be made by the physician mid-procedure, after doing the majority of the work described by a code, to “eliminate” what was to have been the final part or a procedure, essentially “discontinuing” a surgery before accomplishing all of the work listed in the code description, and this is where some question whether Modifier 53 should appropriately be reported instead of 52. However, a physician electing to eliminate the last portion of a procedure for a reason other than an extenuating circumstance/one that threatens the well-being of a patient should still be coded with Modifier 52, notwithstanding the fact that this decision to “eliminate” a portion of the service could constitute a “discontinuation” in a certain sense of the word.

Medicare Guidance Changes for E/M ServicesOctober 11th, 2023 - Wyn Staheli
2023 brought quite a few changes to Evaluation and management (E/M) services. The significant revisions as noted in the CPT codebook were welcome changes to bring other E/M services more in line with the changes that took place with Office or Other Outpatient Services a few years ago. As part of CMS’ Medicare Learning Network, the “Evaluation and Management Services Guide” publication was finally updated as of August 2023 to include the changes that took place in 2023. If you take a look at the new publication (see references below),....
Can We Score Interpretation of an EKG Towards E/M Medical Decision Making?October 10th, 2023 - Aimee Wilcox
When EKGs are performed in the facility setting or even in the physician's office, what are the requirements for reporting the service and who gets credit for scoring data points for Evaluation and Management (E/M) medical decision making (MDM)? Let's take a look at a few coding scenarios related to EKG services to get a better understanding of why this can be problematic.
Accurately Reporting Signs and Symptoms with ICD-10-CM CodesOctober 5th, 2023 - Aimee Wilcox
Coders often find themselves unsure of when to report a sign or symptom code documented in the medical record. Some coders find their organization has an EHR that requires a working diagnosis, which is usually a sign or symptom, be entered to order a test or diagnostic study or image. Understanding the guidelines surrounding when signs and symptoms should be reported is the first step in correct coding so let's take a look at some scenarios.
The 2024 ICD-10-CM Updates Include New Codes for Reporting Metabolic Disorders and Insulin ResistanceSeptember 19th, 2023 - Aimee Wilcox
Diabetes is a chronic disease that just seems to consistently be increasing instead of improving resulting in a constant endeavor by medical researchers to identify causal effects and possible treatments. One underlying or precipitating condition that scientists have identified as a precipitating factor in the development of diabetes is insulin resistance, which is a known metabolic disorder. As data becomes available through claims reporting, additional code options become possible with ICD-10-CM.
Documenting and Reporting Postoperative VisitsSeptember 12th, 2023 - Aimee Wilcox
Sometimes we receive questions regarding documentation requirements for specific codes or coding requirements and we respond with information and resources to support our answers. The following question was recently submitted: Are providers required to report postoperative services on claims using 99024, especially if there is no payment for that service? What documentation is required if you are reporting an unrelated Evaluation and Management (E/M) service by the same physician during the postoperative period?
Understanding Gastroesophageal Reflux Disease and ICD-10-CM CodingAugust 22nd, 2023 - Aimee Wilcox
Gastroesophageal reflux disease or GERD for short, is a disease that impacts millions of Americans on a weekly basis. Symptoms are uncomfortable, as are some of the tests used to diagnose it, but understanding the disease, tests, and treatments helps us better understand how to code the disease using ICD-10-CM codes.
