Unsp infct of urinary tract in pregnancy, second trimester

This code signifies an unconfirmed or unspecified bacterial infection affecting any part of the urinary system (kidneys, ureters, bladder, urethra) occurring during the second trimester of a pregnancy. It indicates that while an infection is suspected or identified, the specific pathogen or precise location within the urinary tract has not been definitively documented.

Apply this code when a pregnant patient in her second trimester presents with symptoms suggestive of a urinary tract infection (UTI), but diagnostic testing (e.g., urine culture) is pending or has not identified a specific organism. It is appropriate when the provider's documentation indicates "unspecified UTI in pregnancy, second trimester" or similar language without further specificity.

• Avoid using this code if the specific pathogen (e.g., E. coli) or a more precise location (e.g., pyelonephritis) is documented; instead, use a more specific O23.- code.
• Always confirm the trimester of pregnancy from the medical record to ensure accurate trimester-specific coding.
• If the infection is confirmed as asymptomatic bacteriuria, use O23.9- instead.
