Psorospermiasis

Psorospermiasis refers to a parasitic infection caused by organisms of the genus Psorospermium, which are typically found in crustaceans. In humans, this condition is extremely rare and usually manifests as cutaneous lesions or subcutaneous nodules. The infection is generally acquired through the ingestion of contaminated seafood.

This code is used when documentation explicitly identifies a diagnosis of psorospermiasis, indicating an infection by Psorospermium species. Supporting documentation would include laboratory confirmation of the parasite or a definitive clinical diagnosis based on characteristic lesions and exposure history.

• Ensure documentation specifies Psorospermium infection; do not use for other parasitic skin conditions.
• Consider additional codes for specific manifestations, such as skin lesions (e.g., abscess, cellulitis), if documented.
• This is a very rare diagnosis; confirm with the provider if encountered.
