Valid for Submission
T67.3XXS is a billable diagnosis code used to specify a medical diagnosis of heat exhaustion, anhydrotic, sequela. The code T67.3XXS is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code T67.3XXS might also be used to specify conditions or terms like anhidrosis, heat exhaustion, heat exhaustion co-occurrent and due to anhidrosis or heat-induced dermatosis. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
T67.3XXS is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like heat exhaustion anhydrotic. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.
The appropriate 7th character is to be added to each code from block Effects of heat and light (T67). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Heat exhaustion
- Heat exhaustion co-occurrent and due to anhidrosis
- Heat-induced dermatosis
Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|922||OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITH MCC||21||1.5876|
|923||OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITHOUT MCC||21||0.9304|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert T67.3XXS to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code T67.3XXS its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Your body normally cools itself by sweating. During hot weather, especially when it is very humid, sweating just isn't enough to cool you off. Your body temperature can rise to dangerous levels and you can develop a heat illness.
Most heat illnesses happen when you stay out in the heat too long. Exercising and working outside in high heat can also lead to heat illness. Older adults, young children, and those who are sick or overweight are most at risk. Taking certain medicines or drinking alcohol can also raise your risk.
Heat-related illnesses include
- Heat stroke - a life-threatening illness in which body temperature may rise above 106 °F (41 °C) in minutes. Symptoms include dry skin, a rapid, strong pulse, dizziness, nausea, and confusion. If you see any of these signs, get medical help right away.
- Heat exhaustion - an illness that can happen after several days of exposure to high temperatures and not enough fluids. Symptoms include heavy sweating, rapid breathing, and a fast, weak pulse. If it is not treated, it can turn into heat stroke.
- Heat cramps - muscle pains or spasms that happen during heavy exercise. You usually get them in your abdomen, arms, or legs.
- Heat rash - skin irritation from excessive sweating. It is more common in young children.
You can lower your risk of heat illness by drinking fluids to prevent dehydration, replacing lost salt and minerals, and limiting your time in the heat.
