News: 395 new 2024 ICD-10-CM codes finalized by CMS, tables and descriptions updated
On June 16, CMS announced 395 new diagnosis codes, 25 deletions, and 13 revisions for the fiscal year (FY) 2024 ICD-10-CM code set, which is finalized to take effect on October 1, 2023. CMS also updated the 2024 addendum, code descriptions in tabular order, and code tables, tabular list, and index in the last week. Among the changes, several dozen new codes pertain to osteoporosis with fractures, retinopathy and muscle entrapment in the eye, and disease of the nervous system, DecisionHealth reported.
The final update will include five new codes for Parkinson’s disease:
- G20.A1, Parkinson’s disease without dyskinesia, without mention of fluctuations
- G20.A2, Parkinson’s disease without dyskinesia, with fluctuations
- G20.B1, Parkinson’s disease with dyskinesia, without mention of fluctuations
- G20.B2, Parkinson’s disease with dyskinesia, with fluctuations
- G20.C, Parkinsonism, unspecified
Also, 123 of the 295 new codes have been added to the external causes of morbidity (V00-Y99) chapter to capture accidents and injuries, such as:
- W44.A1XA, Button battery entering into or through a natural orifice, initial encounter
- W44.C0XA, Glass unspecified, entering into or through a natural orifice, initial encounter
- W44.H2XD, Knife, sword or dagger entering into or through a natural orifice, subsequent
One final code revision was not included in the proposed changes. Code Q85.81, PTEN tumor syndrome, has been changed to PTEN hamartoma tumor syndrome. “PTEN is a tumor suppressor gene that prevents uncontrolled cell growth,” DecisionHealth explained. “PTEN hamartoma tumor syndrome actually is a group of syndromes that involves a change to the PTEN gene that triggers the growth of tumors. A hamartoma is a benign growth composed of an abnormal mix of cells and tissues.”

- 24 new codes added to the diseases of the nervous system (G00-G99) chapter
