Slide 2
Proposal for Changes to ICD-9-CM
- Chapter 16: Symptoms, Signs, and Ill-Defined Conditions (780-799)
- (784) Symptoms involving head and neck

Slide 3
Current Listing in ICD-9-CM
- 784.4 Voice disturbances
- 704.40 Voice disturbance, unspecified
- 784.41 Aphonia, loss of voice
- 784.49 Other
- Change in voice
- Hypernasality
- Dysphonia
- Hyponasality
- Hoarseness

Slide 4
Voice Disturbance vs. Resonance Disorder
| Voice Disturbance |
Resonance Disorder |
| Disorder of phonation
|
Disorder of resonance and nasal air flow |
Symptom of laryngeal disorder
- Affects structure and/or function of larynx
|
Symptom of velopharyngeal dysfunction
- Affects structure and/or function of oral cavity, nasal airway, and/or the velopharyngeal port
|
| Examples: nodules, polyps, GERD, laryngeal cancer, vocal cord paralysis |
Examples: cleft palate, submucous cleft, hypertrophied adenoids |

Slide 5
Resonance Disorders
- Hyponasality - diminished nasality
- Hypernasality - excessive nasality

Slide 6
Why Revise the Code?
- Dysphonia is a disorder of phonation
- Dysphonia is distinct and separate from a disorder of resonance and nasal air flow
- Evaluation techniques and management strategies are different for disorders of phonation versus resonance

Slide 7
Benefits of the New Codes
- Clarifies and specifies the disorder
- Provides a more definitive diagnosis
- Improves communication between disciplines
- Facilitates efficient treatment planning

Slide 8
Proposed Changes to 784.4
- 784.4 Voice and resonance disorders
- 784.40 Voice disorder, unspecified
- 784.41 Aphonia
- 784.42 Dysphonia, Hoarseness
- 784.43 Hypernasality
- 784.44 Hyponasality
- 784.49 Other voice and resonance disorders

Slide 9
By the Way...
Current ICD-10-CM (July 2007)
- R49 Voice disturbances
Excludes1: psychogenic voice disturbance (F44.4)
- R49.0 Dysphonia, Hoarseness
- R49.1 Aphonia, Loss of voice
- R49.2 Hypernasality and Hyponasality
- R49.21 Hypernasality
- R49.22 Hyponasality
- R49.8 Other voice disturbances
- R49.9 Unspecified voice disturbances, Change in voice NOS
