About G24.5

G24.5 is the ICD-10-CM diagnosis code for Blepharospasm. It belongs to category G24 (dystonia), block G20-G26 (extrapyramidal and movement disorders) and chapter 6 (diseases of the nervous system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within G24 (dystonia), G24.5 is specifically for Blepharospasm. Related codes cover drug induced dystonia (G24.0), genetic torsion dystonia (G24.1), idiopathic nonfamilial dystonia (G24.2), Spasmodic torticollis (G24.3), idiopathic orofacial dystonia (G24.4), other dystonia (G24.8) and unspecified (G24.9).

Don't report G24.5 together with the conditions in its Excludes1 note: drug induced blepharospasm (G24.01).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 333.81 (Blepharospasm).
