Infection by Histoplasma Capsulatum Retinitis ICD-10 Code
Question: How do we cross walk ICD-9 code 115.02 Infection by histoplasma capsulatum retinitis to ICD-10? When I look up histoplasmosis in the ICD-10 book, it says B39.9. Looking into this further, I came across H32—Chorioretinal disorders in diseases classified elsewhere. Is there a more specific code we should use? This is unspecified.
Answer: You are correct. The two ICD-10 codes reported are B39.9 and H32. H32 is only three characters. It would be appropriate to use the unspecified histoplasmosis as the ophthalmologist may not know the specific type.
