Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as N39.0. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
  • A bacterial infectious process affecting any part of the urinary tract, most commonly the bladder and the urethra. Symptoms include urinary urgency and frequency, burning sensation during urination, lower abdominal discomfort, and cloudy urine.
  • A disorder characterized by an infectious process involving the urinary tract, most commonly the bladder and the urethra.
  • Infections affecting stuctures participating in the secretion and elimination of urine: the kidneys, ureters, urinary bladder and urethra.
  • Inflammatory responses of the epithelium of the urinary tract to microbial invasions. They are often bacterial infections with associated bacteriuria and pyuria.
  • The urinary system consists of the kidneys, ureters, bladder and urethra. Infections of the urinary tract (utis) are the second most common type of infection in the body. You may have a uti if you notice
    • pain or burning when you use the bathroom
    • fever, tiredness or shakiness
    • an urge to use the bathroom often
    • pressure in your lower belly
    • urine that smells bad or looks cloudy or reddish
    • less frequently, nausea or back pain
    if you think you have a uti, it is important to see your doctor. Your doctor can tell if you have a uti by testing a sample of your urine. Treatment with medicines to kill the infection will make it better, often in one or two days.
