Questions About R44.0Overview

Is R44.0 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report auditory hallucinations on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can R44.0 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the auditory hallucinations is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R44.0?

Under the General Equivalence Mappings, auditory hallucinations converts to ICD-9-CM 780.1 (hallucinations). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
