Other protozoal diseases, not elsewhere classified (B60)

The B60 ICD-10 codes classify various protozoal infections not elsewhere classified, primarily including babesiosis, acanthamebiasis, and naegleriasis. These codes help identify specific parasitic diseases caused by different protozoa, assisting in accurate diagnosis and treatment.

The code B60.0 covers babesiosis, an infection caused by Babesia species such as Babesia microti, Babesia duncani, and Babesia divergens. For example, B60.01 is used for babesiosis due to Babesia microti, often linked to symptoms like hemolytic anemia. The acanthamebiasis group (B60.1) denotes infections by Acanthamoeba species, ranging from corneal ulcers (B60.12 conjunctivitis, B60.13 keratoconjunctivitis) to dangerous meningoencephalitis (B60.11). B60.2 codes primary amebic meningoencephalitis caused by Naegleria fowleri. Other specified protozoal diseases (B60.8) include a broad range of rare parasitic infections. Knowing these ICD-10 codes for protozoal diseases ensures correct coding of infections caused by distinct protozoan agents, improving clinical clarity and management.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • cryptosporidiosis A07.2
  • intestinal microsporidiosis A07.8
  • isosporiasis A07.3

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Acanthamoeba Keratitis

Infection of the cornea by an ameboid protozoan which may cause corneal ulceration leading to blindness.

Babesiosis

A group of tick-borne diseases of mammals including ZOONOSES in humans. They are caused by protozoa of the genus BABESIA, which parasitize erythrocytes, producing hemolysis. In the U.S., the organism's natural host is mice and transmission is by the deer tick IXODES SCAPULARIS.
