A48.52 is a billable and specific ICD-10-CM code. Accurate documentation of A48.52 facilitates proper diagnosis, effective management, and correct reimbursement.
This guideline will provide the use, official coding guidelines, and historical background of A48.52.
What is the ICD-10-CM Diagnosis Code for Wound Botulism?
The ICD-10-CM diagnosis code for Wound Botulism is A48.52.
Botulism is a rare but potentially life-threatening illness caused by toxins produced by the bacterium Clostridium botulinum.
Clostridium botulinum is a spore-forming, anaerobic bacterium that produces one of the most potent neurotoxins known to science: botulinum toxin.
This toxin is one of the most potent neurotoxins known and can lead to severe paralysis if untreated. Botulism occurs in various forms, including:
- Foodborne Botulism
- Infant Botulism
- Wound Botulism
- Inhalation Botulism(there isn’t a specific ICD-10-CM code for inhalation botulism)
Wound botulism is a rare but serious condition caused by Clostridium botulinum bacteria infecting an open wound.
The bacteria produce a toxin that affects the nervous system, leading to muscle weakness, breathing difficulties, and other life-threatening symptoms.
Proper documentation using A48.52 ensures patients receive appropriate care and enables accurate healthcare reimbursement.
Synonyms used for Infant Botulism
- Cutaneous infectious botulism
- Cutaneous toxin-mediated botulism
- Inoculation botulism
- Skin infectious botulism
- Skin toxin-mediated botulism
History Background of ICD-10-CM Diagnosis Code A48.52
The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.
The ICD-9-CM diagnosis code for Wound Botulism is 040.42.This coding remained consistent from 1979 to 2015.
While the ICD-9-CM system offered a basic approach to disease classification, modern healthcare needs more detail and specificity.
To address this, the ICD-10-CM system was launched in 2015, introducing a more comprehensive and accurate coding structure.
The transition from ICD-9-CM to ICD-10-CM significantly improved the ability to document and analyze conditions such as Wound Botulism.
The 2025 edition of ICD-10-CM A48.52 became effective on October 1, 2024.

Symptoms of Infant Botulism
- Weakness or paralysis that starts near the site of the wound and spreads.
- Blurred or double vision, drooping eyelids, difficulty moving the eyes
- difficulty speaking and swallowing
- A dry mouth
- Shortness of breath, dyspnea, or respiratory distress
Other symptoms: Fatigue, vertigo, nausea, diarrhea, vomiting, constipation, or unreactive pupils. Symptoms of wound botulism can appear within days to two weeks. They can start mild but quickly worsen
How Infant Botulism is Caused
When Clostridium botulinum bacteria infect a wound, they can grow and release a harmful toxin. Even small cuts or unnoticed wounds can become infected.
Traumatic injuries or surgical wounds are also at risk. The harmful toxin spreads through the bloodstream and causes nerve damage.
Wound botulism has become more common in recent years. It is especially seen in people who inject heroin. Black tar heroin often contains the bacteria’s spores, making it a major risk factor
Key Causes Include:
- Contaminated needles or equipment used for injecting drugs (e.g., black tar heroin).
- Traumatic injuries that expose deep tissues to soil or debris containing botulinum spores.
Final Thought
Proper coding of A48.52 is essential for diagnosing and managing Wound Botulism. A clear understanding of its symptoms, causes, and coding guidelines ensures accurate documentation and effective treatment. Precise use of this code enhances patient care, supports healthcare planning, and guarantees proper reimbursement for medical services.
