B83.8Other specified helminthiases

B83.8 is the ICD-10-CM diagnosis code for other specified helminthiases. It belongs to category B83 (other helminthiases), block B65-B83 (helminthiases) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within B83, choose B83.8 (Other specified helminthiases) only when documentation doesn't support a more specific option: visceral larva migrans (B83.0), Gnathostomiasis (B83.1), angiostrongyliasis due to Parastrongylus cantonensis (B83.2), Syngamiasis (B83.3), internal hirudiniasis (B83.4) and helminthiasis, unspecified (B83.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235) and DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 128.8 (other specified helminthiasis).
