Single 300 mg injectable dose of cimetidine hydrochloride for reducing stomach acid

This code represents the administration of cimetidine hydrochloride, an H2-receptor antagonist, in a 300 mg injectable dose. Cimetidine is primarily used to reduce stomach acid production, treating conditions such as ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome.

This code is used when a patient receives an intravenous or intramuscular injection of cimetidine 300 mg for the treatment of acid-related gastrointestinal conditions. Documentation should clearly indicate the drug administered, the dosage (300 mg), the route of administration, and the medical necessity for its use.

• Ensure the dosage administered is precisely 300 mg; other dosages may require different codes or units.
• This code represents the drug itself, not the administration service, which should be coded separately (e.g., CPT for injection administration).
• Verify the route of administration (IV or IM) is documented, as this code is specific to injectable forms.
