About coding amebiasis
The ICD-10-CM code for amebiasis is A06.9 (Amebiasis, unspecified). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on A06.9.
Within A06, choose A06.9 (unspecified) only when documentation doesn't support a more specific option: acute amebic dysentery (A06.0), chronic intestinal amebiasis (A06.1), amebic nondysenteric colitis (A06.2), Ameboma of intestine (A06.3), amebic liver abscess (A06.4), amebic lung abscess (A06.5), amebic brain abscess (A06.6), cutaneous amebiasis (A06.7) and 1 more.
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.
