About the B82 Code Range
The ICD-10 code B82 covers diagnoses related to unspecified intestinal parasitism, used when an intestinal parasite infection is identified but not clearly specified. This section includes more detailed codes for particular types and manifestations of intestinal parasitic infections.
ICD-10 code B82.0 is specifically assigned for unspecified intestinal helminthiasis, which refers to infections caused by worm-like parasites such as Cestoda, Trematoda, or Nematoda. Common synonyms include intestinal nematode infection and infections caused by various nematodes, helping coders link these terms to the correct code. Meanwhile, B82.9 is used for intestinal parasitism when the exact parasite is not known but symptoms include inflammation like parasitic duodenal ulcer or parasitic colitis. These distinctions guide healthcare professionals and coders in accurately classifying intestinal parasite infections for proper treatment and record-keeping. Using the appropriate ICD-10 code for intestinal parasitism ensures clear communication about these infections, whether caused by worms or other parasites affecting the intestines.
