Webill: Neurology Coding Strategies for Medical Billing Professionals

Medical billing professionals working in neurology know that this specialty presents a unique set of challenges. From highly technical procedures like EMGs and EEGs to time-based evaluation and management (E/M) services and payer-specific policies, neurology coding requires both precision and a deep understanding of clinical workflows.

Webill provides neurology-focused billing solutions that not only reduce denials and improve accuracy but also help billing professionals stay ahead of changing guidelines. In this guide, we share proven coding strategies to help medical billing professionals improve claim performance, avoid compliance issues, and enhance revenue cycle outcomes for neurology practices.

1. Understand Neurology Procedure Coding Thoroughly

Neurology includes a wide array of oncology billing diagnostic and therapeutic services—many of which require correct sequencing and modifier use. Some of the most frequently billed CPT codes in neurology include:

• 95816 – Routine EEG

• 95910–95913 – Nerve conduction studies

• 95860–95870 – Electromyography (EMG)

• 95930–95941 – Evoked potentials

Strategy:

Use the appropriate CPT code combinations and be familiar with the Correct Coding Initiative (CCI) edits to avoid unbundling errors. When performing EMG and NCS together, ensure the correct number of studies is documented and billed accordingly. Use modifier 59 only when a distinct procedural service is justified by the clinical note.

2. Master Time-Based E/M and Prolonged Services Coding

Neurologists often spend extended time evaluating patients with complex neurological conditions. Since the 2021 E/M updates, coding based on total time has become more prevalent.

Strategy:

• Always capture total time spent on the date of the encounter, including chart review and care coordination.

• Use 99417 (commercial payers) or G2212 (Medicare) for prolonged services when the time threshold is exceeded.

• Ensure documentation supports the time claimed and aligns with the payer’s interpretation of the guidelines.

Accurate time tracking is essential for maximizing reimbursement on high-level visits.

3. ICD-10 Specificity Is Critical in Neurology

Neurology-related ICD-10 codes are extensive and highly specific. Using “unspecified” codes can result in denials or downcoded claims.

Strategy:

• Avoid general codes like G40.909 (unspecified epilepsy) when a more specific code such as G40.311 (generalized idiopathic epilepsy, intractable, with status epilepticus) is appropriate.

• Always ensure that the diagnosis code supports medical necessity for the service being billed, particularly for tests like EEGs, MRIs, and evoked potentials.

• Use coding tools or payer policy databases to confirm that selected diagnoses align with LCD (Local Coverage Determination) criteria.

4. Apply Modifiers with Documentation Support

Modifiers are often required in neurology billing, especially for distinguishing between E/M visits and procedures performed on the same day.

Strategy:

• Modifier 25: Use when an E/M visit is separate and significantly distinct from a procedure performed on the same day. The documentation must clearly describe two separate services.

• Modifier 59: Use to denote distinct procedural services when billing multiple procedures that might otherwise be bundled.

• Ensure every modifier used is justified in the medical record. Inaccurate use can lead to claim rejection or audit triggers.

5. Stay Aligned with Payer Rules and LCDs

Medicare and commercial payers often have specific billing and coding requirements, especially for neurological testing.

Strategy:

• Regularly review LCDs/NCDs and commercial payer policies for services such as EEGs, EMGs, and sleep studies.

• Track policy changes and educate providers about documentation requirements to maintain compliance.

• Use billing software or partners like Webill to integrate these rules directly into the claim review process, flagging potential errors before submission.
