Tetanus neonatorum (A33)
ICD-10 code A33tetanus neonatorum, a serious bacterial infection affecting newborns. This code is used to document cases of tetanus occurring in newborn infants, helping healthcare providers and coders classify and report this particular perinatal infection accurately.
Tetanus neonatorum, also known as tetanus omphalitis, localized tetanus, or simply tetanus with trismus, involves infection that typically begins around the umbilical stump and can cause muscle stiffness, spasms, and the characteristic inability to open the jaw (trismus). Other related terms found in medical records, such as autonomic disorder due to tetanus or tetanic opisthotonus, are encompassed under this code. Using the ICD-10 code for tetanus neonatorum (A33) ensures consistent classification of this dangerous neonatal bacterial condition, aiding in proper treatment documentation and epidemiological tracking.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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.
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.
