ICD-10 code for intestinal helminthiasis

The ICD-10-CM code for intestinal helminthiasis is B82.0 (Intestinal helminthiasis, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B82.0.

Within B82, choose B82.0 (helminthiasis, unspecified) only when documentation doesn't support a more specific option: parasitism, unspecified (B82.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
