R49.8 is a billable diagnosis code used to specify a medical diagnosis of other voice and resonance disorders. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Clinical Information

Hypophonia
the inability to produce speech sounds at normal volume.
High Pitched Cry
an abnormally shrill or screeching vocalization made by infants that could possibly indicate the presence of one of an array of medical conditions or congenital syndromes.
Screaming
a loud, vociferous cry or yell; it can be the result of many emotions, including pain, excitement, or fear.

R49.8 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
154	OTHER EAR, NOSE, MOUTH AND THROAT DIAGNOSES WITH MCC	03	1.5382
155	OTHER EAR, NOSE, MOUTH AND THROAT DIAGNOSES WITH CC	03	0.9466
156	OTHER EAR, NOSE, MOUTH AND THROAT DIAGNOSES WITHOUT CC/MCC	03	0.6555

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

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.

Many things we do can injure our vocal cords. Talking too much, screaming, constantly clearing your throat, or smoking can make you hoarse. They can also lead to problems such as nodules, polyps, and sores on the vocal cords. Other causes of voice disorders include infections, upward movement of stomach acids into the throat, growths due to a virus, cancer, and diseases that paralyze the vocal cords.

Signs that your voice isn't healthy include:

Your voice has become hoarse or raspy
You've lost the ability to hit some high notes when singing
Your voice suddenly sounds deeper
Your throat often feels raw, achy, or strained
It's become an effort to talk

Treatment for voice disorders varies depending on the cause. Most voice problems can be successfully treated when diagnosed early.

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.
