Q/A: How Many Diagnosis Codes do I use?
April 15th, 2019 - Wyn Staheli, Director of Research
Question: My patient has a lot of chronic conditions. Do I need to include all these on the claim? I know that I can have up to 12 diagnoses codes on a single claim. What if I need more than that?
Answer: More is not always better. You only need to include the code(s) which most appropriately describe the condition being treated. For example, if the patient has hypertension, but your assessment does not address their hypertension or the management of that condition, then do not include it on your claim. Likewise, if the condition will not alter your treatment/services provided, then do not include it on the claim. This is based on the ICD-10-CM Official Guidelines for Coding and Reporting which states that “all documented conditions that coexist at the time of the encounter/visit, and require or affect patient care, treatment, or management” should also be coded.
One more important thing to remember: if they were previously treated for a condition, but that condition no longer exists or affects the management of their CURRENT condition, do not include it. This can be problematic in some patient EHR systems which carry forward previous diagnoses to a new date of service. Be sure that you review the patient list and only include those conditions affecting the current treatment.
As for the question about having more than 12 diagnoses, in a chiropractic office, generally there really would not be a need to document that many diagnoses. However, if they have resolved conditions that were previously treated but that have not been billed, you could split the claim so that those are on a separate claim which would allow you to have space for more diagnosis codes to be reported.

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.
