2026 ICD-10-CM Diagnosis Code T36.1X2APoisoning by cephalosporins and other beta-lactam antibiotics, intentional self-harm, initial encounter

AHRQ’s CCSR groups this code into broader clinical categories.

• Aztreonam

  a monocyclic beta-lactam antibiotic originally isolated from chromobacterium violaceum. it is resistant to beta-lactamases and is used in gram-negative infections, especially of the meninges, bladder, and kidneys. it may cause a superinfection with gram-positive organisms.

• Cefaclor

  semisynthetic, broad-spectrum antibiotic derivative of cephalexin.

• Cefadroxil

  long-acting, broad-spectrum, water-soluble, cephalexin derivative.

• Cefamandole

  semisynthetic wide-spectrum cephalosporin with prolonged action, probably due to beta-lactamase resistance. it is used also as the nafate.

• Cefatrizine

  orally active semisynthetic cephalosporin antibiotic with broad-spectrum activity.

• Cefazolin

  a semisynthetic cephalosporin analog with broad-spectrum antibiotic action due to inhibition of bacterial cell wall synthesis. it attains high serum levels and is excreted quickly via the urine.

• Cefixime

  a third-generation cephalosporin antibiotic that is stable to hydrolysis by beta-lactamases.

• Cefmenoxime

  a cephalosporin antibiotic that is administered intravenously or intramuscularly. it is active against most common gram-positive and gram-negative microorganisms, is a potent inhibitor of enterobacteriaceae, and is highly resistant to hydrolysis by beta-lactamases. the drug has a high rate of efficacy in many types of infection and to date no severe side effects have been noted.

• Cefmetazole

  a semisynthetic cephamycin antibiotic with a broad spectrum of activity against both gram-positive and gram-negative microorganisms. it has a high rate of efficacy in many types of infection and to date no severe side effects have been noted.

• Cefonicid

  a second-generation cephalosporin administered intravenously or intramuscularly. its bactericidal action results from inhibition of cell wall synthesis. it is used for urinary tract infections, lower respiratory tract infections, and soft tissue and bone infections.

• Cefoperazone

  semisynthetic broad-spectrum cephalosporin with a tetrazolyl moiety that is resistant to beta-lactamase. it may be used to treat pseudomonas infections.

• Cefotaxime

  semisynthetic broad-spectrum cephalosporin.

• Cefotetan

  a semisynthetic cephamycin antibiotic that is administered intravenously or intramuscularly. the drug is highly resistant to a broad spectrum of beta-lactamases and is active against a wide range of both aerobic and anaerobic gram-positive and gram-negative microorganisms.

• Cefotiam

  one of the cephalosporins that has a broad spectrum of activity against both gram-positive and gram-negative microorganisms.

• Cefoxitin

  a semisynthetic cephamycin antibiotic resistant to beta-lactamase.

• Cefsulodin

  a pyridinium-substituted semisynthetic, broad-spectrum antibacterial used especially for pseudomonas infections in debilitated patients.

• Ceftazidime

  semisynthetic, broad-spectrum antibacterial derived from cephaloridine and used especially for pseudomonas and other gram-negative infections in debilitated patients.

• Ceftizoxime

  a semisynthetic cephalosporin antibiotic which can be administered intravenously or by suppository. the drug is highly resistant to a broad spectrum of beta-lactamases and is active against a wide range of both aerobic and anaerobic gram-positive and gram-negative organisms. it has few side effects and is reported to be safe and effective in aged patients and in patients with hematologic disorders.

• Ceftriaxone

  a broad-spectrum cephalosporin antibiotic and cefotaxime derivative with a very long half-life and high penetrability to meninges, eyes and inner ears.

• Cefuroxime

  broad-spectrum cephalosporin antibiotic resistant to beta-lactamase. it has been proposed for infections with gram-negative and gram-positive organisms, gonorrhea, and haemophilus.

• Cephalexin

  a semisynthetic cephalosporin antibiotic with antimicrobial activity similar to that of cephaloridine or cephalothin, but somewhat less potent. it is effective against both gram-positive and gram-negative organisms.

• Cephalosporinase

  a cephalosporin antibiotic.

• Cephaloglycin

  a cephalorsporin antibiotic.

• Cephaloridine

  a cephalosporin antibiotic.

• Cephalosporins

  a group of broad-spectrum antibiotics first isolated from the mediterranean fungus acremonium. they contain the beta-lactam moiety thia-azabicyclo-octenecarboxylic acid also called 7-aminocephalosporanic acid.

• First Generation Cephalosporins

  cephalosporin agents with excellent coverage against gram-positive cocci, such as staphylococcus and streptococcus. they have some activity against the gram-negative bacteria, but in general, gram-negative activity is decreased compared to 2nd, 3rd, and 4th generation cephalosporins.

• Second Generation Cephalosporins

  agents with less activity against gram-positive cocci than first generation cephalosporins but have increased activity against gram-negative bacilli.

• Third Generation Cephalosporins

  agents that are structurally similar to other cephalosporins but have a broader spectrum of activity against bacteria than the first and second generation cephalosporins. these agents cover more resistant streptococcus, staphylococcus, gram-positive anaerobes, and more resistant strains of haemophilus, neisseria, proteus, escherichia coli, and klebsiella (hnpek).

• Cephalothin

  a cephalosporin antibiotic.

• Cephradine

  a semi-synthetic cephalosporin antibiotic.

• Clavulanic Acid

  a beta-lactam antibiotic produced by the actinobacterium streptomyces clavuligerus. it is a suicide inhibitor of bacterial beta-lactamase enzymes. administered alone, it has only weak antibacterial activity against most organisms, but given in combination with other beta-lactam antibiotics it prevents antibiotic inactivation by microbial lactamase.

• Clavulanic Acids

  acids, salts, and derivatives of clavulanic acid (c8h9o5n). they consist of those beta-lactam compounds that differ from penicillin in having the sulfur of the thiazolidine ring replaced by an oxygen. they have limited antibacterial action, but block bacterial beta-lactamase irreversibly, so that similar antibiotics are not broken down by the bacterial enzymes and therefore can exert their antibacterial effects.

Antibiotics

Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.
