AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2020 Issue 4; New/Revised ICD-10-CM Codes
Cytokine Release Syndrome
Codes have been created for cytokine release syndrome (CRS) that distinguish grades of severity. CRS and cytokine storm syndrome (CSS) are used synonymously in literature. CRS is a systemic inflammatory response to infections and certain immunotherapies, such as monoclonal antibodies and chimeric antigen receptor (CAR) T-cell therapy that cause activation of the immune system. Lymphocytes and/or myeloid cells cause a massive and rapid release of cytokines into the blood. Cytokines are small proteins that act as cell messengers to help direct the body’s immune response. The reaction to the cytokine release ranges from mild symptoms to life-threatening organ...

Article Overview
This article provides a coding-oriented overview of cytokine release syndrome (CRS), including its relationship to cytokine storm syndrome, common clinical contexts in which it occurs, and the general severity-grading framework referenced by the source. It is intended for coding and reimbursement professionals who need to understand how CRS is discussed in clinical literature and how documented grade information relates to ICD-10-CM reporting.
Why This Topic Matters
CRS may be documented in a variety of settings, including immunotherapy and transplant-related care, and the article helps readers understand the terminology and grading concepts that influence diagnostic coding and record review.
