ICD-10 Code B45.8 – Other forms of cryptococcosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B45.8 – Other forms of cryptococcosis
What it is
B45.8 identifies cryptococcal infection in forms not captured by the other cryptococcosis codes. Use it when documentation clearly states another cryptococcal site or presentation, but not meningitis or pulmonary disease.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect cryptococcal infection outside the central nervous system or lungs, with site-specific symptoms noted in the record.
When to use this code
Use B45.8 when the clinician documents cryptococcosis in an other, specified form and the record does not support a more specific cryptococcosis code. It may apply when the infection site is described clearly but does not match the common categories. If the note is vague, check documentation before assigning the code.
Do not use for
Do not use this code for cryptococcal meningitis or pulmonary cryptococcosis, which have separate codes. Also avoid it when the documentation only says “cryptococcosis” without a specified form.
Coding tip
Match the code to the documented site or form of cryptococcosis, and query for clarification if the record is nonspecific.
