B33.0

What This Code Means

Epidemic myalgia is a viral infection that causes sudden onset of severe muscle pain and inflammation, typically affecting the chest, abdomen, or limbs. It spreads through communities and is often caused by enteroviruses like coxsackievirus B.

Coding Tips

• •Verify the specific causative virus if documented, as some enterovirus codes may provide more specificity than B33.0
• •Ensure the condition is documented as epidemic or occurring in an outbreak context to distinguish from other myalgia diagnoses
