Neurology practices face some of the most complex billing challenges in healthcare. From high-cost injectable drugs and neurostimulator devices to DME, infusion services, and Medicare-specific requirements, accurate HCPCS coding is critical for clean claims and timely reimbursement. Even a minor coding error can trigger denials, audits, or delayed payments.
This Neurology HCPCS Codes Cheat Sheet by Allzone is designed to help neurologists, billing teams, and revenue cycle professionals quickly understand commonly used HCPCS Level II codes in neurology, how they are applied, and best practices to improve billing accuracy.
What Are HCPCS Codes and Why They Matter in Neurology Billing
HCPCS (Healthcare Common Procedure Coding System) codes are standardized codes used to report supplies, durable medical equipment (DME), non-physician services, and injectable drugs. While CPT codes describe physician services and procedures, HCPCS Level II codes complement CPT codes, especially for Medicare, Medicaid, and commercial payers.
In neurology, HCPCS codes are essential for:
-
- Injectable and biologic drugs
- Neurostimulator devices and supplies
- Botox and chemodenervation agents
- Infusion and injection supplies
- DME used in neurological care
Accurate HCPCS coding ensures proper reimbursement, compliance, and reduced claim denials.
Common HCPCS Code Categories Used in Neurology
Neurology practices typically rely on the following HCPCS code ranges:
| HCPCS Code Range | Category |
| J0000–J9999 | Injectable drugs |
| L0000–L9999 | Orthotics, prosthetics & neurostimulators |
| E0000–E9999 | Durable medical equipment (DME) |
| A0000–A0999 | Medical and injection supplies |
| C0000–C9999 | Outpatient hospital devices |
| G0000–G9999 | Medicare-specific services |
Neurology HCPCS Codes Cheat Sheet
1. Injectable Drugs & Biologics (J Codes)
Injectable medications are among the highest-revenue and highest-risk services in neurology billing.
Frequently used J codes include:
-
- J0585 – Injection, onabotulinumtoxinA (Botox)
- J0586 – Injection, abobotulinumtoxinA (Dysport)
- J0587 – Injection, rimabotulinumtoxinB (Myobloc)
- J1459 – Immune globulin (IVIG)
- J1561–J1569 – IVIG products
- J2323 – Natalizumab (used in multiple sclerosis)
💡 Billing Tip from Allzone: Always document drug name, dosage, wastage, NDC number, and medical necessity to avoid drug-related denials.
2. Chemodenervation & Botox Supply Codes
Botox billing is one of the most scrutinized areas in neurology.
Common supporting HCPCS codes:
-
- J0585 – Botox (per unit)
- A4550 – Surgical trays
- A4215 – Needle, sterile
- A4245 – Alcohol wipes
Proper unit calculation and wastage reporting (JW modifier when applicable) are essential for reimbursement accuracy.
3. Neurostimulator Devices & Implants (L Codes)
Used for conditions like Parkinson’s disease, epilepsy, chronic pain, and movement disorders.
Common neurology L codes:
-
- L8679 – Neurostimulator pulse generator
- L8680 – Implantable neurostimulator electrode
- L8686 – Replacement neurostimulator battery
- L8689 – External neurostimulator pulse generator
📌 These codes often require prior authorization and payer-specific documentation, especially under Medicare.
4. Durable Medical Equipment (DME) Used in Neurology (E Codes)
Neurology practices may prescribe DME for mobility, respiratory support, or neurological impairment.
Common E codes include:
-
- E0100 – Cane
- E0114 – Crutches
- E0143 – Walker
- E0601 – CPAP device (sleep neurology)
- E0470 – Bi-level respiratory assist device
Allzone recommends verifying DME eligibility, rental vs purchase rules, and proof of medical necessity before claim submission.
5. Infusion & Injection Supplies (A Codes)
Supplies are often overlooked but are crucial for accurate billing.
Common A codes:
-
- A4215 – Sterile needle
- A4221 – Infusion pump supplies
- A4550 – Surgical tray
- A4649 – Miscellaneous medical supply
Missing supply codes can lead to underbilling and revenue leakage.
6. Medicare-Specific Neurology HCPCS Codes (G Codes)
G codes are temporary or Medicare-only codes commonly used in neurology.
Examples:
-
- G0453 – Prolonged infusion monitoring
- G0500 – Moderate sedation (facility settings)
- G2211 – Visit complexity add-on (when applicable)
G codes are highly payer-specific and must be reviewed annually.

Neurology CPT + HCPCS Mapping Table (Billing Cheat Sheet)
Below is a practical CPT–HCPCS mapping table neurologists and billing teams can use to ensure clean claims.
Common Neurology CPT to HCPCS Crosswalk
| Neurology Service | CPT Code | HCPCS Code | Description |
| Botox Injection (Migraine, Spasticity) | 64615 / 64642–64647 | J0585 | Botox (per unit) |
| Chemodenervation Supplies | — | A4215, A4550 | Needles, trays |
| IVIG Infusion | 96365–96368 | J1459 / J1561–J1569 | Immune globulin |
| MS Infusion Therapy | 96413 | J2323 | Natalizumab |
| Deep Brain Stimulator Implant | 61863–61867 | L8679, L8680 | Neurostimulator & leads |
| Neurostimulator Battery Replacement | 61885 | L8686 | Battery |
| EEG with Disposable Supplies | 95816–95819 | A4556 | EEG electrodes |
| Sleep Apnea Device | 95810 | E0601 | CPAP device |
| Mobility Assistance | — | E0100, E0114 | Cane, crutches |
| Prolonged Monitoring (Medicare) | 99215 | G2211 | Visit complexity add-on |
📌 Important:CPT codes describe physician work; HCPCS codes describe drugs, devices, and supplies. Both must align for reimbursement.
