Coding in the COVID Era: How to Decipher COVID-19 Diagnosis Coding and Reporting

Tuesday, May 18, 2021 | Jammie Quimby

With 15+ years as a certified coder, I have seen firsthand how important it is to understand diagnosis coding and the complex guidelines that come with it. However, you may ask just how important can it be? It’s a pretty big deal because it drives the medical necessity for payment of services rendered. As coders, we want to accurately capture all services rendered for our providers. Getting them the maximum allowed reimbursement by applying the guidelines correctly is one of our main goals. So how is this defined? Medicare defines medical necessity as “Health care services or supplies needed to diagnose or treat an illness, injury, condition, disease, or its symptoms and meet accepted standards of medicine.”

COVID-19 Diagnosis Reporting

In early 2020, in response to the COVID-19 pandemic, new ICD-10-CM codes were released to identify this condition as well as new ICD-10-CM guidelines for coding and reporting. The new codes were made effective on April 1, 2020, followed by updates to the coding and guidance. Each fiscal year on Oct. 1, ICD-10-CM updates are released including new codes, deleted codes and revised codes, and official coding and reporting guidelines.

In mid-December of 2020, after the 2021 ICD-10-CM new fiscal year had already been in effect, the Centers for Medicare & Medicaid Services (CMS) implemented six new diagnosis codes for reporting additional conditions related to COVID-19 on medical claims effective Jan. 1, 2021. Because of this, there were new updates made to the 2021 ICD-10-CM official coding and reporting guidelines. Below are the current diagnosis codes and descriptions available for reporting specific to COVID-19 in the current 2021 ICD-10-CM fiscal year.

 

Applying the Guidelines

As coders know, there are some gray areas when applying guidelines to services rendered. My best advice: If you find an area in any guidelines that doesn’t clearly explain a situation, it’s always best to call your carriers directly to ask for guidance. If you can get this in writing from them, even better. That way you will have something you can refer back to and even use in an appeal if needed.

Below is a table that illustrates the differences in coding and reporting when applying the guidelines released.


Final Thoughts

It is increasingly important to stay on top of coding and guidance changes, keeping in mind that ICD-10-CM is updated every fiscal year, on Oct. 1. Typically, the Centers for Disease Control and Prevention and CMS will release new ICD-10-CM updates in June of each year. This gives you time to review and implement any training needed to prepare before the Oct. 1 start date.
