Reader Question:

Use 87086 and 87088 for Urine Culture

Question: The internist obtained a Medicare patient's urine culture for suspected urinary infection. Which CPT and ICD-9 codes will Medicare accept?

Answer: You should report either 87086 (Culture, bacterial; quantitative colony count, urine) or 87088 (... with isolation and presumptive identification of isolates, urine), depending on how your internist performed the test.
 
Usually, a physician performs a urine culture with colony count (87086) to determine the approximate number of bacteria present per milliliter of urine. When you bill 87088, the doctor has generally used a commercial kit to identify additional, significant bacteria.

Also, to medically justify reporting the codes, you should meet the following Medicare criteria:
 
 

  •  A patient has abnormal urinalysis results that suggest a urinary tract infection, such as hematuria, pyuria or proteinuria.
     
  •  The patient has clinical symptoms, such as urinary  frequency (788.41) and burning (788.1, Dysuria), that indicate a possible urinary tract infection
     
  •  The internist performs the urine culture to follow up on a previously treated urinary tract infection to confirm the therapy's effectiveness.
     
  •  A physician evaluates the patient for a fever of unknown origin (780.6) or suspect septicemia (038.x).

    As for appropriate ICD-9 codes for urine cultures, you should first check the internist's documentation for the physician's diagnosis. Generally, however, Medicare accepts the following diagnosis codes:
     

  •  038.0-038.9 - Septicemia
     
  •  580.0-589.9 - Nephritis, nephrotic syndrome, and  nephrosis
     
  •  590.0-599.9 - Other diseases of urinary system
     
  •  600-608.9 - Diseases of male genital organs
     
  •  780.6 - Pyrexia of unknown origin
     
  •  788.0-788.9 - Symptoms involving urinary system
     
  •  790.7 - Bacteremia
     
  •  791.0 - Proteinuria
     
  •  791.7 - Other cells and casts in urine.
