Infections of bladder in pregnancy, second trimester

This code signifies a urinary tract infection specifically affecting the bladder (cystitis) that occurs during the second trimester of a pregnancy. It indicates an active infectious process within the lower urinary system of a pregnant patient.

Apply this code when documentation confirms a diagnosis of cystitis in a pregnant patient who is currently in her second trimester. Supporting documentation would include urinalysis results indicating infection, positive urine culture, and physician notes confirming the diagnosis and gestational stage.

• Always confirm the trimester of pregnancy documented by the provider.
• Do not use for asymptomatic bacteriuria; a confirmed infection of the bladder is required.
• Sequence this code as the principal diagnosis if the reason for the encounter is the bladder infection.
