Cryptosporidiosis

This code represents a parasitic infection of the gastrointestinal tract caused by Cryptosporidium species. It typically manifests as watery diarrhea, abdominal cramps, nausea, and low-grade fever, particularly in immunocompromised individuals. The infection can also affect other organ systems, such as the respiratory tract or biliary tree, in severe cases.

Assign this code for documented cases of cryptosporidiosis confirmed by laboratory identification of Cryptosporidium oocysts in stool or other bodily fluids. It is appropriate for both acute and chronic presentations of the infection. Documentation should clearly state the diagnosis of cryptosporidiosis.

• Differentiate from other parasitic enteritis codes; ensure specific documentation of Cryptosporidium.
• Consider an additional code for manifestations like dehydration (e.g., 276.51) or malabsorption (e.g., 579.9) if documented.
• For immunocompromised patients, ensure the underlying condition (e.g., HIV, malignancy) is coded first, followed by cryptosporidiosis as an opportunistic infection.
