Template:ICD10 Guideline Fistulas

Additional Info

• A fistula is an abnormal connection between one hollow structure (which may be an organ such as bladder, stomach, or a blood vessel OR a "space" such as the peritoneal space or the thoracic cavity), or the external surface (i.e. skin).
• We have specific codes for some, but not all fistulas:
  • Tracheostomy complication, tracheo-esophageal fistula
  • Fistula involving stomach or duodenum
  • Anus or rectum, fistula
  • Intestinal fistula
  • Bladder, fistula, to anywhere
  • Female genital tract, fistula (to anywhere)
• For a fistula involving a hollow structure for which we do not have a specific fistula code, then use the appropriate NOS code -- e.g. for a fistula involving the gallbladder, use Gallbladder or bile duct disorder, NOS
• RULE FOR CODING FISTULA:
  • In general, combine the codes for both structures involved -- e.g. for a fistula between the bladder and intestine ("enterovesicular fistula"), combine Intestinal fistula and Bladder, fistula, to anywhere
  • When the fistula goes from a hollow structure to the skin (external) then only code the hollow structure itself --- e.g. an anal fistula to the skin just code: Anus or rectum, fistula

Coding Fistulas in ICD10

This is a placeholder so Allan can write the instructions that should show up in all fistula pages. I have already placed calls to it to all pages in.
