Infections of prt urinary tract in pregnancy, unsp trimester

This code signifies a urinary tract infection (UTI) affecting areas other than the bladder or kidney, such as the urethra or ureters, occurring during any trimester of pregnancy. It represents an infection of the urinary system in a pregnant patient where the specific location within the urinary tract is not further specified beyond "other parts."

Use this code when the medical record documents a pregnant patient with symptoms and/or laboratory confirmation of a UTI, and the provider specifies the infection is in a part of the urinary tract other than the bladder (cystitis) or kidney (pyelonephritis), but does not provide further anatomical specificity. Documentation should clearly indicate the patient's pregnant status and the presence of a UTI in an unspecified "other" location.

• Do not use this code if the documentation specifies cystitis (O23.4-) or pyelonephritis (O23.0-) in pregnancy.
• Always sequence this code as a secondary diagnosis following the code for the obstetric condition (e.g., Z3A.- for weeks of gestation).
• Ensure the medical record supports the "unspecified trimester" aspect; if the trimester is known, a more specific code from the O23.3- category should be used.
