R68.0

Hypothermia, not associated with low environmental temperature

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R68.0 is a billable code used to indicate a diagnosis of hypothermia, not associated with low environmental temperature.

Key Diagnostic Point:

Hypothermia is defined as a body temperature below 95°F (35°C) that can occur due to various medical conditions rather than exposure to cold environments. This condition can arise from metabolic disorders, endocrine dysfunctions, or as a side effect of certain medications. Symptoms may include confusion, shivering, slurred speech, slow breathing, and fatigue. In clinical settings, hypothermia can be identified through physical examination and laboratory tests that reveal low body temperature and altered mental status. It is crucial to differentiate this type of hypothermia from environmental causes, as the management and underlying conditions may differ significantly. The diagnosis requires careful assessment of the patient's history, including any recent illnesses, medications, or metabolic conditions that could contribute to the hypothermic state. Laboratory findings may include electrolyte imbalances, altered glucose levels, and abnormal thyroid function tests, which can help identify the underlying cause.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between environmental and non-environmental causes
  • Need for comprehensive patient history and clinical assessment
  • Potential overlap with other codes related to temperature regulation
  • Variability in clinical presentation based on underlying conditions

Audit Risk Factors

  • Inadequate documentation of the patient's history and symptoms
  • Failure to specify the underlying cause of hypothermia
  • Misclassification of hypothermia as environmental when it is not
  • Lack of supporting lab findings in the medical record
