What is Hand Foot Mouth Disease?
Definition and Overview
Hand foot mouth disease (HFMD) is a contagious viral illness characterized by sores in the mouth and rashes on the hands and feet. It is primarily caused by enteroviruses, most notably coxsackievirus A16 and enterovirus 71. While it is generally mild, HFMD can sometimes lead to complications, especially in immunocompromised individuals or when caused by certain virus strains.
Who is at Risk?
- Children under 10 years old.
- Individuals in close-contact settings such as daycares and schools.
- Immunocompromised persons.
- Occasionally, adults can contract HFMD, usually with milder symptoms.

ICD-10 Coding for Hand Foot Mouth Disease
Understanding ICD-10 Classification
The ICD-10 system, developed by the World Health Organization (WHO), provides standardized codes for diseases and health conditions. Proper coding is crucial for medical documentation, billing, and epidemiological tracking.
ICD-10 Code for Hand Foot Mouth Disease
The primary ICD-10 code for hand foot mouth disease is:
- B08.4 — Enteroviral vesicular stomatitis with rash
This code encompasses infections caused by enteroviruses that manifest with vesicular lesions in the mouth and characteristic skin rashes on the hands and feet.
Note: Sometimes, clinicians may also use more specific codes depending on the presentation or complications, such as:
- A84.9 — Viral encephalitis, unspecified (if neurological complications occur).
- B34.81 — Enterovirus infection, unspecified, when the specific virus strain is unidentified.

Details About the ICD-10 Code B08.4
Definition and Scope
B08.4 specifically refers to enteroviral vesicular stomatitis with rash, which includes HFMD caused by various enteroviruses. It covers the clinical presentation of vesicles and rash associated with enteroviral infections in children and adults.
Criteria for Coding
When assigning ICD-10 codes, clinicians should document:
- Confirmed diagnosis of HFMD.
- Presence of vesicular lesions in the mouth.
- Rashes on the palms, soles, or other parts of the body.
- Laboratory confirmation, if available.

Symptoms and Clinical Features of Hand Foot Mouth Disease
Common Symptoms
- Fever
- Reduced appetite
- Sore throat
- Malaise
- Painful sores in the mouth
- Rash or blisters on the palms, soles, knees, or buttocks
Signs to Watch For
- Ulcers in the mouth
- Red spots and blisters on hands and feet
- Irritability in children
- Fever lasting 2-3 days
---
Diagnosis and Testing
Clinical Diagnosis
Most cases are diagnosed based on the characteristic appearance of sores and rashes. Medical history and physical examination are primary.
Laboratory Tests
- Throat swabs
- Stool samples
- Polymerase chain reaction (PCR) testing for enteroviruses
- Viral culture
These tests can confirm the specific causative virus and assist in epidemiological tracking.

Management and Treatment
Supportive Care
Since HFMD is viral, antibiotics are ineffective. Treatment focuses on relieving symptoms:
- Maintaining hydration
- Using over-the-counter pain relievers (acetaminophen or ibuprofen)
- Applying topical oral anesthetics for mouth sores
- Ensuring good hygiene to prevent spread
When to Seek Medical Attention
- Severe mouth pain impairing eating or drinking
- Signs of dehydration
- High fever lasting more than a few days
- Symptoms of neurological complications (e.g., neck stiffness, severe headache)
---
Prevention Strategies
- Frequent handwashing with soap and water
- Avoiding close contact with infected persons
- Cleaning and disinfecting surfaces and toys
- Educating caregivers and children about hygiene
---
Complications and Prognosis
Most children recover fully within a week or two. However, some may experience complications such as:
- Viral meningitis
- Encephalitis
- Dehydration due to painful mouth sores
Prompt medical care usually results in a good prognosis.

Importance of Accurate Coding in Healthcare
Why Proper ICD-10 Coding Matters
Accurate coding ensures:
- Proper reimbursement for healthcare providers.
- Reliable epidemiological data for public health surveillance.
- Correct tracking of disease outbreaks.
- Clear communication among healthcare professionals.
Common Coding Challenges
- Differentiating between enteroviral infections.
- Coding for complications separately.
- Updating codes based on new virus strains or guidelines.

Summary
Understanding the ICD-10 classification for hand foot mouth disease is vital for healthcare providers, researchers, and public health officials. Using the correct ICD-10 code, primarily B08.4, facilitates accurate diagnosis, treatment, and epidemiological tracking of this common childhood illness. Although HFMD is usually mild and self-limited, awareness of its clinical features, prevention methods, and appropriate coding enhances overall healthcare quality and disease management.
