ICD-9-CM Voice and Resonance Codes Revised Starting in October 2009

(07/09/2009)

There will be new and revised diagnostic codes for voice and resonance disorders beginning on October 1, 2009. The National Center for Health Statistics (NCHS) of the U.S. Department of Health and Human Services Centers for Disease Control and Prevention coordinates and maintains the disease and disorder codes for the International Classification of Diseases, 9th Revision, Clinical Modification. NCHS recently posted the ICD-9-CM Tabular Addenda that goes into effect for fiscal year 2010 (October 1, 2009).

ASHA presented a proposal for the revision and expansion of codes to the ICD-9-CM Coordination and Maintenance Committee on March 12, 2009. As the result of the work of Dee Adams Nikjeh of the ASHA Health Care Economics Committee and Special Interest Division 3, the 784.4 series is modified from "voice disturbance" to "voice and resonance disorders" and will be as follows:

784.4 Voice and resonance disorders
784.40 Voice and resonance disorder, unspecified (revised)
784.41 Aphonia, Loss of voice
784.42 Dysphonia (new code), Hoarseness
784.43 Hypernasality (new code)
784.44 Hyponasality (new code)
784.49 Other voice and resonance disorders (revised)

NCHS expanded the 784.5 series to read as:
784.5 Other speech disturbance
Excludes: speech disorder due to late effect of cerebrovascular accident (438-10–438.19)
(added) 784.51 Dysarthria (new code)
Excludes: dysarthria due to late effect of cerebrovascular accident (438.13)
784.59 Other speech disturbance (new code)
Dysphasia
Slurred speech
Speech disturbance NOS (not otherwise specified)
