CPT® Code 95861

Quick Reference

• Code definition: CPT 95861 covers needle electromyography of two extremities, including any related paraspinal area EMG performed in the same session, when no nerve conduction studies (NCS) are performed that day.
• Key billing rule: MUE = 1; report 95861 once per date of service regardless of how many muscles are tested across the two extremities. The code cannot be stacked.
• Modifier essentials: Modifier 26 applies when a physician interprets a study performed in a facility EMG lab; modifier TC applies for the technical component only. Modifiers 50, LT, and RT do not apply; the code's bilateral scope is defined by extremity count, not laterality.
• Documentation must-have: The EMG report must name each muscle tested, the side, and per-muscle findings (insertional activity, spontaneous activity, MUAP characteristics, recruitment pattern) with a signed physician interpretation. A global or summary-only report will not support the claim.
• Top confusion point: When NCS is performed on the same date, 95861 does not apply. The correct pathway is NCS primary code (95907-95913) plus add-on per-extremity EMG codes (95885 or 95886). Reporting 95861 alongside 95885/95886 for the same session is incorrect.
• Payer alert: In hospital outpatient settings, 95861 carries an APC status of STV-Packaged; it does not receive separate OPPS payment and is bundled into the encounter.

When to Use This Code

CPT 95861 applies when a physician performs needle EMG on exactly two limbs during a single session, with no NCS performed that day. Two extremities means any combination of two limbs: both upper extremities, both lower extremities, or one upper and one lower. Right arm plus left arm equals two extremities. Right arm plus right leg equals two extremities. The count is based on distinct limbs, not the number of muscles, insertions, or sides of the body.

The code is appropriate for evaluating radiculopathy, peripheral neuropathy, plexopathy, mononeuropathy, myopathy, neuromuscular junction disorders (myasthenia gravis), and motor neuron disease (ALS) when the clinical question requires sampling two limbs. Paraspinal muscles related to the extremity under study (cervical paraspinals with upper extremity EMG, lumbar paraspinals with lower extremity EMG) are included in 95861 and are not separately billable.

For a complete study, CPT guidelines specify that five or more muscles must be tested per extremity. If fewer than five muscles are tested in an extremity, report 95870 for that limited assessment rather than 95861. When both NCS and EMG are performed in the same encounter, do not report 95861; use the NCS primary code (95907-95913) with add-on codes 95885 or 95886 per extremity.

Needle EMG must be personally performed by the physician, who also provides the interpretation. Technician-only performance without direct physician involvement does not support billing for the professional component.

Code Differentiation Table

The most critical differentiator is the presence or absence of concurrent NCS. When NCS (95907-95913) is performed in the same session, the entire EMG must be reported via 95885 or 95886 per extremity; 95861 is not appropriate regardless of how many extremities were studied. The second differentiator is the completeness rule: 95861 applies when five or more muscles are tested per extremity; 95870 applies for the limited scenario of four or fewer.

Billing & Modifier Rules

Modifier 26 and TC: PC/TC Indicator = 1 applies to 95861. When a physician performs and interprets the study in their own non-facility office using their own equipment, bill globally (no modifier). When a facility provides the equipment and technical staff and the physician provides interpretation only, the physician bills 95861-26 and the facility bills 95861-TC. Split billing requires both components to be reported separately; submitting both 26 and TC from the same entity is incorrect.

Modifier 51: No multiple procedure payment reduction applies (database-confirmed Multiple Procedures indicator = 0). Do not append modifier 51 to 95861.

Modifiers 50, LT, RT: These do not apply. Bilateral scope is inherent in the code descriptor through extremity count, not laterality designation. Bilateral indicator = 0 confirms the 150% bilateral payment adjustment does not apply.

Modifier 59: May be appropriate when 95861 is billed with another distinct procedure on the same date that would otherwise be bundled, but 95861 itself does not require modifier 59 as a matter of routine.

Add-on codes: 95940 (continuous intraoperative neurophysiology monitoring, 15-minute increments) and 95941 (remote intraoperative monitoring, per hour) may be listed in addition to 95861 when intraoperative monitoring is performed as part of or alongside the study. These are add-on codes and require a primary procedure.

MUE and frequency: MUE = 1. CPT 95861 may be billed only once per date of service. Since the code already captures 2 extremities, there is no mechanism to report it twice to cover additional extremities; select 95863 or 95864 if three or four extremities were actually studied.

Bundling: 95861 is mutually exclusive with 95860, 95863, and 95864. Only one extremity-count EMG code may appear per session. It is also bundled with 95885 and 95886 for the same date via CPT guidelines; NCCI edits enforce this. Do not report 95861 in conjunction with 96002 (dynamic surface EMG), per published CPT guidelines.

Documentation Essentials

The EMG report is the primary audit target for 95861 claims. Documentation must include:

• Pre-study clinical context: Chief complaint, symptom duration and character, relevant exam findings (motor strength grade by muscle, deep tendon reflex findings, sensory deficits), and the clinical question that prompted the study.
• Muscles tested: Each muscle listed by name and laterality (e.g., "right biceps brachii," "left tibialis anterior"). The record must identify which two extremities were studied. Omitting specific muscle names and sides is the most common reason claims are denied or downcoded on audit.
• Per-muscle findings: Insertional activity (normal, increased, decreased), spontaneous activity (fibrillations, positive sharp waves, fasciculations, complex repetitive discharges), MUAP amplitude, duration, morphology, stability, and recruitment pattern. A table format is acceptable; a narrative summary without per-muscle data is not.
• Physician interpretation: Clinical correlation of EMG findings to the differential diagnosis, with a specific conclusion (e.g., "Electrodiagnostic findings are consistent with an active L5-S1 radiculopathy, right lower extremity"). The report must be signed by the interpreting physician.
• Paraspinal documentation: If paraspinal muscles were studied, document them by segment and side. Their findings support the extremity code but do not create a separate billable service.

Auditors specifically flag studies where the report documents only one extremity's muscles but the claim was submitted as 95861 (2 extremities). Billing must reflect what is documented.

Medicare, Commercial & Medicaid Payer Rules

Medicare:

Multiple MACs maintain active LCDs covering electrodiagnostic medicine that govern 95861. Coverage requires documented medical necessity: the EMG must be ordered to diagnose or manage a specific neuromuscular condition. Screening EMG without documented clinical indication does not meet medical necessity and will be denied. Covered indications typically include peripheral neuropathy, radiculopathy, plexopathy, mononeuropathy, myopathy, motor neuron disease, and neuromuscular junction disorders, though specific covered ICD-10-CM codes vary by MAC jurisdiction. Verify the applicable LCD at cms.gov/medicare-coverage-database using the local contractor for the service area.

MUE = 1 is enforced at the claim level. Medicare does not pay separately for 95861 in the hospital outpatient setting; the APC status is STV-Packaged (database-confirmed), meaning payment is included in the facility encounter rate. Physicians billing the professional component (95861-26) in a facility setting receive the facility non-facility RVU rate. CMS classifies 95861 as TOS 5 (Diagnostic Laboratory) under the Medicare fee schedule.

Most MACs require the interpreting physician to hold credentials in electrodiagnostic medicine (neurology, physical medicine and rehabilitation, or equivalent specialty with documented training). The physician must personally perform the needle insertion and be present throughout the study.

Frequency limitations are not codified as a fixed annual cap in most LCD policies, but repeat testing requires documentation of a new clinical question or change in clinical status. Routine interval EMG without documented clinical change will be denied as not medically necessary.

Commercial payers:

Commercial payer policies generally follow CPT guidelines for code selection but may impose prior authorization requirements for electrodiagnostic studies. Some payers apply diagnosis-based restrictions, limiting coverage to specific ICD-10-CM codes. Automated bundling edits at commercial payers may incorrectly bundle 95861 with NCS codes even when the CPT pathway would support separate reporting; when EMG is performed without NCS, modifier 59 or documentation of the standalone encounter may be needed to override the edit.

Common Denials & Prevention

Denial: Insufficient documentation The submitted EMG report does not name specific muscles or does not include per-muscle findings. Auditors and automated claim review systems flag reports that provide only a narrative summary or a diagnosis without supporting muscle-level data. Prevention: Require a structured EMG report template that captures each muscle by name and side with discrete fields for insertional activity, spontaneous activity, MUAP characteristics, and recruitment before the claim is submitted.

Denial: Code not supported by documentation (extremity count mismatch) The report documents muscles in only one extremity, but 95861 (2 extremities) was billed. This is a direct overcoding finding and a high-risk audit target. Prevention: Implement a pre-billing audit step that cross-references the number of distinct limbs listed in the report against the CPT code billed. Correct to 95860 before claim submission.

Denial: Bundled with NCS codes 95861 appears on the same claim as 95907-95913 or 95885/95886. Payer edits or NCCI bundling logic deny 95861 when NCS is present. Prevention: When NCS and EMG are performed in the same session, route the claim through the correct pathway: NCS primary code plus 95885/95886 per extremity. Remove 95861 from any claim that also contains NCS codes for the same date.

Denial: Medical necessity not established The claim lacks a supporting diagnosis or the billed diagnosis does not appear on the MAC's covered diagnosis list for the applicable LCD. Prevention: Confirm the ordering diagnosis maps to an LCD-covered ICD-10-CM code before scheduling. Document the clinical indication explicitly in the pre-study assessment section of the EMG report.

Denial: MUE exceeded Two units of 95861 appear on the same claim date. Some billing systems allow multiple units to be entered for codes that ordinarily have an MUE of 1. Prevention: Configure the billing system to enforce MUE = 1 for 95861. If three or four extremities were studied, bill 95863 or 95864, not 95861 × 2.

Coding Scenarios

Scenario 1: Bilateral upper extremity EMG, no NCS

A neurologist performs needle EMG of the right and left upper extremities in a patient with bilateral hand numbness and grip weakness. Six muscles are tested in each arm. No NCS is performed at this visit. The report documents each muscle by name and side with complete per-muscle findings and a signed interpretation consistent with bilateral carpal tunnel syndrome.

Correct coding: 95861 with diagnosis G56.00 (carpal tunnel syndrome, unspecified upper limb) or G56.01/G56.02 for laterality

Why: Two extremities studied, no concurrent NCS, complete study (6 muscles per extremity exceeds the 5-muscle threshold). Paraspinal findings, if any, are included in 95861 and not separately billed.

Scenario 2: Same-day EMG and NCS, 2 extremities

A neurologist performs both NCS (eight studies) and needle EMG on bilateral lower extremities in the same session for a patient with suspected polyneuropathy. Seven muscles are tested per extremity across at least four spinal levels.

Correct coding: 95910 (7-8 NCS studies) + 95886 × 2 (complete add-on EMG, each lower extremity) with diagnosis G62.9

Why: NCS performed same day triggers the add-on pathway; 95861 is not reported. Each extremity meets the complete study threshold (5+ muscles, appropriate nerve/level representation), so 95886 rather than 95885 applies per limb.

Scenario 3: Split billing in hospital outpatient EMG lab

A physiatrist performs and interprets a needle EMG of both lower extremities in a hospital outpatient EMG lab. The hospital provides the equipment, recording technician, and supplies.

Correct coding: Hospital bills 95861-TC; physiatrist bills 95861-26

Why: PC/TC Indicator = 1 permits split component billing. The hospital owns the equipment (TC); the physician provides the interpretation and signed report (26). Neither party bills the global code. Note: the hospital outpatient APC payment for 95861-TC is packaged into the encounter rate.

Scenario 4: Overcoding correction during pre-bill audit

A coder reviewing a claim finds 95861 billed for a session where the EMG report documents only left lower extremity muscles: tibialis anterior, peroneus longus, gastrocnemius medial head, and vastus lateralis (four muscles total, one extremity).

Correct coding: 95870 (limited study, 1 extremity, 4 or fewer muscles)

Why: Only one extremity is documented, and fewer than five muscles were studied, making this a limited rather than complete study. Billing 95861 misrepresents both the extremity count and the study scope.
