HCPCS code J0588: IncobotulinumtoxinA, per 1 unit2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for J0588 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What J0588 covers

IncobotulinumtoxinA, marketed as Xeomin, is a botulinum toxin used to reduce excessive muscle activity or salivary secretion. Neurologists, physiatrists, ophthalmologists, and other clinicians may administer it by injection for conditions such as cervical dystonia, spasticity, blepharospasm, or chronic sialorrhea. The treatment site and injection approach depend on the condition being treated.

J0588 identifies the drug, not the injection service. One HCPCS unit represents one unit of incobotulinumtoxinA; report the quantity administered in those units, not in milliliters or vials. Its physician fee schedule status is E, so CMS excludes it from the physician fee schedule. When Medicare covers the drug, payment is under another method; HCPCS classifies it as a Part B drug, generally priced using CMS quarterly Average Sales Price drug pricing files. The Medicare contractor determines coverage.
