Ampersand symbol

Symbol: &
meaning: and

As an abbreviation, this symbol is typically used to join together some single-letter abbreviations joined by the word and.

• Do not insert a space before or after the ampersand.
• As it is typically used in an abbreviated in medical documentation, it is not used in operative titles or in diagnoses.

dilatation and currettage: D&C
tonsillectomy and adenoidectomy: T&A

CAUTION: When abbreviated forms using letters and the word "and" (for which the ampersand may be used as a substitute) are dictated, the "and" sounds like an "n." It is a common error for transcriptionists to insert an "n" instead of the ampersand. For example, TNA instead of T&A. Be careful about making this type of error.
