About coding Chill
The ICD-10-CM code for Chill is R68.83 (Chills (without fever)). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R68.83.
Within R68.8, choose R68.83 (Chills (without fever)) only when documentation doesn't support a more specific option: early satiety (R68.81), decreased libido (R68.82), jaw pain (R68.84) and other general symptoms and signs (R68.89).
Don't report R68.83 together with the conditions in its Excludes1 note: chills with fever (R50.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
