Code Description

ICD-10 R68.83 is a billable code used to indicate a diagnosis of chills (without fever).

Key Diagnostic Point:

Chills without fever, classified under R68.83, refer to the sensation of coldness accompanied by shivering or shaking, occurring in the absence of an elevated body temperature. This symptom can arise from various underlying conditions, including infections, metabolic disorders, or psychological factors. Chills may be a response to environmental factors, such as exposure to cold temperatures, or may indicate a physiological reaction to stress or anxiety. In clinical practice, it is essential to differentiate chills from fever, as the presence of fever often suggests an infectious process. The absence of fever in patients experiencing chills necessitates a thorough evaluation to identify potential causes, which may include endocrine disorders, such as hypothyroidism, or acute stress responses. Accurate documentation of the patient's history, associated symptoms, and any relevant laboratory findings is crucial for appropriate coding and management.

Complexity Factors

  • Differentiating chills from fever and other similar symptoms.
  • Identifying underlying causes that may not be immediately apparent.
  • Need for comprehensive patient history and physical examination.
  • Potential overlap with other ICD-10 codes for similar symptoms.

Audit Risk Factors

  • Inadequate documentation of the absence of fever.
  • Failure to document associated symptoms or clinical findings.
  • Misclassification of chills as a symptom of a fever-related condition.
  • Lack of clarity regarding the underlying cause of chills.
