Speech-Language Pathology ICD-10-CM Code Changes for 2024

The following new and revised ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) codes are effective October 1, 2023, for fiscal year (FY) 2024. ICD-10-CM codes are updated annually. For past updates, see speech-language pathology ICD-10-CM code changes for 2023 and 2022.

There are no major changes to ICD-10-CM codes directly related to speech, language, cognitive, swallowing, or voice disorders for FY 2024. However, SLPs should be aware that the 2024 ICD-10-CM expands the family of diagnosis codes describing Parkinson’s disease for greater specificity. For a full list of changes to the code set, see the NCHS 2024 release of ICD-10-CM.

Note: Always check with payers regarding coverage of new or revised ICD-10-CM codes. Coding changes may not always alter payer coverage decisions for specific conditions.

ASHA Notes

  • SLPs may use these new ICD-10-CM codes to provide additional detail regarding Parkinson’s as an underlying or coexisting condition to the speech, language cognitive, swallowing, or voice disorder.
  • Consult the medical record or referring physician before reporting Parkinson’s disease in addition to the treating diagnosis on the claim.
