What T71 covers · when clinicians use it
ICD-10 code T71 identifies Asphyxiation in the U.S. ICD-10-CM clinical and billing record set. It sits within the Injury, Poisoning & External Causes chapter (S00–T88), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply T71 when an encounter's findings match the Asphyxiation description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify T71 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for T71 and is a coding reference, not clinical, diagnostic, or billing advice.
Asphyxiation (T71) refers to various external environmental effects on human health, ranging from radiation sickness to thermal injuries, temperature-related conditions, pressure-related issues, asphyxiation, deprivation, abuse, and adverse reactions not classified elsewhere. Timely recognition and management of these effects are crucial for survival and recovery.
Symptoms
- Nausea, vomiting, and weakness (radiation sickness)
- Heat exhaustion, cramps, or heatstroke symptoms (heat effects)
- Shivering, numbness, and confusion (hypothermia)
- Dizziness or unconsciousness (air/water pressure effects)
- Breathing difficulties or cyanosis (asphyxiation)
- Physical signs of neglect or abuse
- Unexpected allergic or adverse reactions to external exposures
Diagnosis
Diagnosis depends on clinical history, physical examination, environmental exposure details, and diagnostic tests like imaging, blood work, or oxygen saturation levels. Abuse and neglect cases involve thorough evaluations, multidisciplinary assessments, and often legal interventions. Prompt diagnosis is critical to mitigate further harm and plan effective interventions.
ICD10 Code Usage
The ICD10 code T71 is used across emergency medicine, critical care, forensic medicine, and social services documentation. It supports accurate recording of health effects from environmental, chemical, and social exposures, ensuring appropriate treatment, follow-up care, legal action when necessary, and insurance claim processing.

FAQs
Q1: What does ICD10 code T71 refer to?
A: It covers a range of external causes leading to medical conditions like radiation sickness, hypothermia, abuse, or adverse environmental effects.
Q2: Is radiation sickness common?
A: It is rare but can occur in nuclear accidents, radiation therapy complications, or occupational exposures.
Q3: How is hypothermia treated?
A: Treatment involves gradual rewarming, supportive care, and monitoring for complications.
Q4: How are abuse cases coded?
A: Confirmed abuse is coded under T74, while suspected cases fall under T76.
Q5: Why is accurate coding important for external causes?
A: It ensures timely intervention, legal protection, appropriate care, and proper health surveillance reporting.
Conclusion
Documenting external cause-related conditions accurately with ICD10 code T71 supports immediate care, legal and social interventions, and better long-term health outcomes for affected individuals. Accurate records strengthen healthcare response systems and public health monitoring efforts.
