121.9
ICD-9-CMThis code signifies a parasitic infection caused by trematodes (flukes) when the specific type of trematode or the exact location of the infection is not documented. It represents a general diagnosis of fluke infestation without further specification.
Use this code when medical record documentation confirms a trematode infection, but the physician has not specified the genus or species of the fluke (e.g., Schistosoma, Fasciola, Clonorchis). This code is appropriate when the diagnostic workup is incomplete or the specific trematode cannot be identified.
