Patient EducationClinical

Voice Disorders

Voice is the sound made by air passing from your lungs through your larynx, or voice box. In your larynx are your vocal cords, two bands of muscle that vibrate to make sound. For most of us, our voices play a big part in who we are, what we do, and how we communicate. Like fingerprints, each person's voice is unique.

Questions About R49.8Overview

Is R49.8 (Voice and resonance disorders) a billable code?

What MS-DRG does R49.8 group to?

When other voice and resonance disorders is the principal diagnosis on an inpatient stay, it groups to MS-DRG 154, 155, 156, with relative weights from 0.6911 to 1.5635 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R49.8 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the other voice and resonance disorders is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R49.8?

Under the General Equivalence Mappings, other voice and resonance disorders converts to ICD-9-CM 784.49 (voice/resonance dis NEC). 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.
