What are urinary tract infection-related ICD-10 codes can I use?
- N39.0 - Urinary tract infection, site not specified
This ICD-10 code is meant to be used on a patient confirmed to have a urinary tract infection (UTI). UTIs are caused by the entry of bacteria into a person's urethra, leading to various undesirable complications. Some examples of these complications include experiencing a burning or painful sensation during urination, the presence of bloody urine, and the occurrence of groin cramps. UTIs commonly affect either the bladder, which is the most frequent site, or the kidney, which is less common but more severe. However, in the context of this specific ICD-10 code, the location of the UTI is unspecified.
- A02.25 - Salmonella pyelonephritis
This ICD-10 code is meant to be used on a patient confirmed to have Salmonella Pyelonephritis, which is a type of urinary tract infection in the kidneys. It is serious problem that needs to be addressed as soon as possible because it can damage the kidneys, leading to life-threatening complications. This type of condition is caused by salmonella. If a patient has a coliform urinary tract infection (UTI caused by E. coli bacteria) and the kidneys are affected, this ICD-10 code can be used.
- A41.9 - Sepsis, unspecified organism
This ICD-10 code is meant to be used on a patient confirmed to being going through sepsis, but it isn’t known yet as to what particular organism is causing the sepsis. If you have a patient that is undergoing sepsis because of a urinary tract infection, this ICD-10 can be used.
- N13.6 - Pyonephrosis
This ICD-10 code is meant to be used on a patient confirmed to have Pynoephrosis, which is a kidney-related problem. If a person has this, that means their kidneys are infected, and there is pus in the renal pelvis. This is often caused by blockages/obstructions in the urinary tract that stem from Pyelonephritis.
- O04.88 - Urinary tract infection following (induced) termination of pregnancy
This ICD-10 code is meant to be used on a female patient confirmed to have a urinary tract infection that resulted from the induced termination of their pregnancy. It’s possible for females to be afflicted with a urinary tract infection during pregnancy, after giving birth, or after their pregnancy is terminated.
- P39.3 - Neonatal urinary tract infection
This ICD-10 code is meant to be used on infant patients confirmed to have urinary tract infection. Another word for newborns is neonates, so this means that this ICD-10 code is only meant for diagnosing newborn babies.
These are some of the urinary tract infection ICD codes you can use.
