Also known as
Anaphylactic shock due to exposure to cause
Covers anaphylactic shock from various external causes.
Angioneurotic edema
Swelling similar to anaphylaxis but without shock.
Other adverse effects, not elsewhere classified
Includes unspecified allergic reactions when a more precise code isn't available.
Toxic effects of venom
Relevant for anaphylaxis triggered by insect stings or bites.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the shock anaphylactic in nature?
Yes
Is the cause documented?
No
Do NOT code for anaphylactic shock. Code the underlying condition.
When to use each related code
| Description |
|---|
| Severe, potentially life-threatening allergic reaction. |
| Mild to moderate allergic reaction. |
| Allergic reaction to food. |
Missing documentation of allergen, manifestation, or severity can lead to less specific coding (e.g., allergic reaction NOS) impacting reimbursement.
Incorrectly coding the cause of anaphylaxis (food, medication, insect sting) can lead to inaccurate data for quality reporting and research.
Respiratory or cardiovascular complications during anaphylaxis must be coded separately to reflect the full severity for accurate risk adjustment.
Q: What are the most effective first-line management strategies for anaphylactic shock in a clinical setting?
A: The cornerstone of anaphylactic shock management is immediate intramuscular administration of epinephrine (1:1000 concentration, 0.3-0.5 mg for adults, 0.01 mg/kg for children) into the anterolateral thigh. This should be followed by securing the airway, supplemental oxygen, and aggressive fluid resuscitation with intravenous crystalloids (e.g., normal saline) at rapid rates. Place the patient in a recumbent position with elevated legs. Closely monitor vital signs, including blood pressure, heart rate, and oxygen saturation. Beyond the initial stabilization, consider administering adjunctive treatments such as antihistamines (H1 and H2 blockers) and corticosteroids. However, these should never delay epinephrine administration. Explore how integrated protocols can streamline anaphylaxis management in your clinical practice.
Q: How can I differentiate between anaphylaxis and other conditions that mimic its presentation, such as a panic attack or vasovagal syncope, to ensure accurate diagnosis and avoid misdiagnosis?
A: Differentiating anaphylaxis from other conditions requires a thorough clinical assessment, encompassing a detailed history of potential allergen exposure, symptom onset and progression, and physical examination findings. While both panic attacks and vasovagal syncope can share symptoms like hypotension, tachycardia, and altered mental status, they lack the characteristic features of anaphylaxis, such as urticaria, angioedema, and respiratory compromise (wheezing, stridor). Crucially, skin and mucosal changes are typically absent in panic attacks and vasovagal episodes. Consider implementing a structured diagnostic approach incorporating validated clinical criteria (e.g., the Brighton Collaboration criteria) to improve diagnostic accuracy and minimize the risk of misdiagnosis. Learn more about specific features that can help differentiate between these conditions.
Patient presented with acute onset of anaphylaxis, a severe and potentially life-threatening allergic reaction. Symptoms included urticaria, pruritus, angioedema of the face and lips, and respiratory distress manifested as dyspnea and wheezing. The patient reported exposure to a known allergen (specify allergen) approximately (timeframe) prior to symptom onset. Differential diagnosis included other causes of angioedema and respiratory compromise, such as hereditary angioedema and acute asthma exacerbation. Given the rapid onset of symptoms following allergen exposure and the presence of characteristic skin and respiratory findings, the diagnosis of anaphylactic shock was made. Immediate treatment was initiated with intramuscular epinephrine injection, followed by intravenous fluids and supplemental oxygen. Diphenhydramine and corticosteroids were administered for symptom management and to mitigate the risk of biphasic anaphylaxis. Patient response to treatment was positive with resolution of urticaria, angioedema, and respiratory distress. The patient's vital signs stabilized with return to baseline blood pressure, heart rate, and oxygen saturation. Patient education was provided regarding allergen avoidance, emergency preparedness, and the proper use of epinephrine auto-injectors. The patient was discharged in stable condition with a prescription for an epinephrine auto-injector and instructions for follow-up with an allergist for further evaluation and management of their allergy. ICD-10 code T78.00XA (initial encounter for other anaphylactic shock, unspecified cause) and relevant procedural codes for medication administration and other interventions were documented.
