Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code A35:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Tetanus NOS

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • obstetrical tetanus A34
  • tetanus neonatorum A33

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code A35 are found in the index:


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Cephalic tetanus
  • Generalized tetanus
  • Infection due to Clostridium tetani
  • Localized tetanus
  • Tetanic opisthotonus
  • Tetanus
  • Tetanus complicating ectopic AND/OR molar pregnancy
  • Tetanus with trismus

Clinical Information

  • 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.
  • TETANUS ANTITOXIN-. an antitoxin used for the treatment of tetanus.
  • TETANUS TOXIN-. protein synthesized by clostridium tetani as a single chain of ~150 kda with 35% sequence identity to botulinum toxin that is cleaved to a light and a heavy chain that are linked by a single disulfide bond. tetanolysin is the hemolytic and tetanospasmin is the neurotoxic principle. the toxin causes disruption of the inhibitory mechanisms of the cns thus permitting uncontrolled nervous activity leading to fatal convulsions.

Information for Patients


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 immunization. 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.
