Effects of heat and light
This range includes codes for various heat-related conditions, including heatstroke and heat exhaustion.
Malignant hyperthermia due to anesthesia
Specific to hyperthermia triggered by anesthesia, requiring detailed documentation of anesthesia exposure.
Environmental hyperthermia of newborn

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| T67.0 | Heatstroke and sunstroke | Use when the patient presents with severe hyperthermia and CNS dysfunction due to heat exposure. |
|
| T88.3 | Malignant hyperthermia due to anesthesia | Use when hyperthermia is triggered by anesthesia during a surgical procedure. |
|
| P81.0 | Environmental hyperthermia of newborn | Use for newborns with hyperthermia due to environmental factors, not infection. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Hyperthermia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code T67.0.
Impact
Clinical: Misrepresentation of the patient's condition., Regulatory: Potential audit issues due to incorrect coding., Financial: Loss of reimbursement due to incorrect DRG assignment.
Mitigation Strategy
Ensure detailed documentation of symptoms and environmental factors., Use specific hyperthermia codes when applicable.
Impact
Reimbursement: Incorrect sequencing can lead to reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data representation of patient conditions.
Mitigation Strategy
Ensure etiology-first sequencing, such as X30 before T67.0.
Impact
Lack of specific environmental details can lead to audit findings.
Mitigation Strategy
Ensure all environmental factors are documented in detail.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
