Chills ICD-10-CM Codes

The ICD-10 diagnosis code for chills is R68.83 (Chills without fever), classified under other nonspecific symptoms and signs. This code is used when chills occur as a standalone symptom without an accompanying fever.

The appropriate ICD-10 diagnosis code for fever and chills depends on the clinical context. If both symptoms are present without a clear underlying cause, R50.9 (Fever, unspecified) is commonly used, and it also falls under other nonspecific symptoms.

In ICD-9, the diagnosis code for chills is typically 780.64 (Chills without fever), which is also grouped under other general symptoms.
