A33 is a billable ICD-10 code used to specify a medical diagnosis of tetanus neonatorum. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The code A33 is applicable to newborn patients only. It is clinically and virtually impossible to use this code on a non-newborn patient.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Localized tetanus
- Tetanic opisthotonus
- Tetanus neonatorum
- Tetanus omphalitis
- Tetanus with trismus
- Trismus present
- Trismus-. spasmodic contraction of the masseter muscle resulting in forceful jaw closure. this may be seen with a variety of diseases, including tetanus, as a complication of radiation therapy, trauma, or in association with neoplastic conditions.
- Tetanus-. a disease caused by tetanospasmin, a powerful protein toxin produced by clostridium tetani. tetanus usually occurs after an acute injury, such as a puncture wound or laceration. generalized tetanus, the most common form, is characterized by tetanic muscular contractions and hyperreflexia. localized tetanus presents itself as a mild condition with manifestations restricted to muscles near the wound. it may progress to the generalized form.
- Funisitis-. an acute inflammation of the umbilical cord. it is characterized by the presence of polymorphonuclear cells migrating from the fetal umbilical cord vessels through the umbilical cord towards the bacteria containing amniotic fluid.
- Necrotizing Funisitis|Sclerosing Funisitis|Sclerosing Funisitis-. a ring of karyorrhectic debris that may exhibit dystrophic mineralization and/or identifiable fetal neutrophil infiltrate in wharton's jelly that is oriented towards the amniotic surface. the cord has a denser ring externally and a fainter ring centrally.
- Grade 1 Trismus, CTCAE|CTCAE Grade 1 Trismus (difficulty, restriction or pain when opening mouth)|Grade 1 Trismus|Grade 1 Trismus (difficulty, restriction or pain when opening mouth)-. decreased rom (range of motion) without impaired eating
- Grade 2 Trismus, CTCAE|CTCAE Grade 2 Trismus (difficulty, restriction or pain when opening mouth)|Grade 2 Trismus|Grade 2 Trismus (difficulty, restriction or pain when opening mouth)-. decreased rom requiring small bites, soft foods or purees
- Grade 3 Trismus, CTCAE|CTCAE Grade 3 Trismus (difficulty, restriction or pain when opening mouth)|Grade 3 Trismus|Grade 3 Trismus (difficulty, restriction or pain when opening mouth)-. decreased rom with inability to adequately aliment or hydrate orally
- Trismus-. lack of ability to open the mouth fully due to decreased range of motion of the muscles of mastication. it may be a symptom of tetanus.
- Trismus, CTCAE|Trismus|Trismus|Trismus (difficulty, restriction or pain when opening mouth)-. a disorder characterized by lack of ability to open the mouth fully due to a decrease in the range of motion of the muscles of mastication.

Tetanus is a serious illness caused by Clostridium bacteria. The bacteria live in soil, saliva, dust, and manure. The bacteria can enter the body through a deep cut, like those you might get from stepping on a nail, or through a burn.
The infection causes painful tightening of the muscles, usually all over the body. It can lead to "locking" of the jaw. This makes it impossible to open your mouth or swallow. Tetanus is a medical emergency. You need to get treatment in a hospital.
A vaccine can prevent tetanus. It is given as a part of routine childhood vaccination. Adults should get a tetanus shot, or booster, every 10 years. If you get a bad cut or burn, see your doctor - you may need a booster. Immediate and proper wound care can prevent tetanus infection.
