CPT code 95907 – Nerve conduction studies, 1-2 studies

Key takeaways

CPT code 95907 covers 1-2 nerve conduction studies, counted per study (each motor, sensory or mixed nerve test), not per electrode placement.

Codes 95908-95913 cover higher study counts, and billing the wrong tier is a frequent denial cause.

CPT 95886 is an add-on code reported with 95907-95913, so it needs no modifier 59 or XS when billed with 95907.

Medicare RVUs for 95907 are national, and payment varies by GPCI locality. Check the CMS Physician Fee Schedule Look-Up Tool for your rate.

CPT code 95907: official descriptor and code overview

CPT code 95907 is the nerve conduction study code for 1-2 studies per session, as defined in the American Medical Association’s CPT code set. Also, it sits under the Nerve Conduction Tests heading (95905-95913) in the Neurology and Neuromuscular Procedures subsection of the Medicine section.

First, a study for counting purposes is one motor, sensory or mixed nerve conduction test. For example, testing the median nerve for sensory conduction is one study, and adding ulnar motor conduction is a second. In other words, the count runs per nerve conduction study, not per electrode placement or waveform recorded.

CPT 95907 sibling code family (95908-95913)

Moreover, the AMA assigns a separate code for each study-count tier. Therefore, select the code that matches the number of nerve conduction studies performed and documented, not the number of extremities examined.

Additionally, payers flag study-count mismatches between the billed code and the documented report. For example, if the report lists two studies but the claim shows 95908 or a higher code, the payer will either downcode or deny. For this reason, document every study by nerve name and direction in the interpretation report before assigning the code.

CPT 95907 vs CPT 95886: key differences

CPT 95907 covers nerve conduction studies. CPT 95886 is needle electromyography of one extremity, with related paraspinal areas when performed, done with nerve conduction studies. Specifically, it describes a complete study of five or more muscles, innervated by three or more nerves or four or more spinal levels.

Because 95886 is an add-on code, it is only reported alongside a primary NCS code from 95907-95913. However, the two tests measure different things, and both are often ordered in the same encounter.

As a result, a same-session claim carries one NCS tier code plus an EMG add-on for each extremity tested. Finally, the diagram below shows how the codes combine.

Documentation requirements for billing CPT 95907

First, every 95907 claim requires a signed physician interpretation in the medical record. In addition, the study count documented in the report must exactly match the code billed. Moreover, these five elements must appear in the encounter documentation before submitting the claim, since missing any one will prevent submitting a clean claim:

1. Clinical indication: the symptom or diagnosis justifying the study (e.g., numbness and weakness in median nerve distribution, suspected carpal tunnel syndrome)
2. Nerves tested and directions: name each nerve and specify whether it was studied in the motor or sensory direction (e.g., “right median nerve, sensory antidromic”)
3. Waveform data per nerve: record latency (ms), amplitude (mV or uV), and conduction velocity (m/s) for each study
4. Signed physician interpretation: the performing or supervising physician must sign the written interpretation in the record before the claim is submitted
5. ICD-10 diagnosis linked to the study: the referring diagnosis must map directly to a covered condition under the applicable MAC’s local coverage determination

Ultimately, the study count in the report is the number that determines which NCS code to bill. For instance, if the documentation lists two nerve studies performed, bill 95907 and nothing higher, regardless of how many electrode placements were required.

ICD-10 diagnosis codes commonly paired with CPT 95907

Also, payers cross-reference the billed ICD-10 code against the MAC’s local coverage determination for electrodiagnostic studies. As a result, a diagnosis not covered under the applicable LCD results in a denial regardless of documentation quality. For example, these ICD-10 codes are commonly paired with CPT 95907:

Therefore, always confirm that the submitted diagnosis appears on the covered-diagnosis list in the MAC’s active LCD before billing. Moreover, MACs differ, so a code covered under Noridian’s LCD for electrodiagnostic studies may not be covered under CGS or WPS.

Medicare reimbursement for CPT code 95907

Specifically, Medicare pays for CPT code 95907 under the CMS Physician Fee Schedule. In addition, its RVUs are set nationally each year, and the dollar payment varies by Geographic Practice Cost Index (GPCI) locality. Next, the table below shows the 2026 national RVU components for the global service.

Consequently, facility and non-facility totals match because the global service covers both parts of the test. However, a physician who only interprets the study bills the professional component with modifier 26, and the equipment owner bills the technical component with modifier TC.

Instead, for dollar amounts, use the FastRVU 2026 RVU lookup or the CMS PFS Look-Up Tool with the GPCI for your locality. For this reason, dollar values are not published here because they change each January 1.

Payer requirements, LCDs, and prior authorization

Next, Medicare coverage for CPT code 95907 is governed by the applicable MAC’s local coverage determination. Additionally, several MACs have active LCDs for electrodiagnostic studies, so check the CMS LCD database for the current LCD number in your jurisdiction. Furthermore, medical billing requirements for electrodiagnostic services also differ from routine E/M billing. Therefore, key requirements across most MAC policies include:

• First, a documented clinical history, physical examination findings, and the specific neuromuscular symptoms that justify the study
• Second, evidence of prior conservative treatment or clinical evaluation that failed to establish a diagnosis without electrodiagnostic testing
• Third, an order from the referring physician naming the suspected diagnosis or clinical question
• Also, the study must be performed and interpreted by the billing physician or under appropriate supervision, consistent with CMS diagnostic test supervision requirements (42 CFR 410.32)
• Also, commercial payers may require prior authorization, especially for patients covered under Medicare Advantage plans

Furthermore, some MACs limit the number of NCS studies reimbursable per encounter or per year for certain diagnoses. As a result, exceeding that limit without documented medical necessity leads to partial denial, even when each study is clinically appropriate.

Modifiers for CPT code 95907

Finally, the applicable modifier depends on who performs and interprets the study and whether the procedure is repeated. For this reason, use the AAPC Codify CPT lookup to verify current modifier-indicator assignments for 95907 before submitting claims.

NCCI edits and bundling rules

Next, needle EMG codes fall into two groups for NCS billing. First, the add-on codes 95885-95887 describe needle EMG done with nerve conduction studies, so they are reported alongside 95907-95913. In contrast, the standalone codes 95860-95870 describe needle EMG performed without NCS.

Also, the NCCI edits for electrodiagnostic codes are updated quarterly, so check the CMS NCCI tool for current edit pairs. As a result, the rules apply to 95907 like this:

• NCS with needle EMG: report 95907 with the EMG add-on that fits the study (95885, 95886 or 95887), with no modifier 59 or XS
• Limited and complete EMG on one limb: an NCCI edit pairs 95885 against 95886 for the same extremity. Report the one that matches the muscles studied
• Autonomic testing codes (95923, 95925-95927) are not bundled with 95907 and are billed separately without a modifier
• Intraoperative monitoring codes (95940 and G0453) are distinct services and not subject to NCCI edits with 95907 in a standard outpatient encounter

Common denial reasons for CPT 95907 and how to avoid them

Overall, CPT code 95907 denials follow recognizable patterns, and each has a straightforward fix when caught before submission. In addition, denial management workflows for electrodiagnostic practices should track these six categories separately.

In addition, for guidance on reading the codes that accompany each rejected claim, see denial codes in medical billing. For example, CARC 97 (payment included in another service) appears when a payer bundles a line, such as 95885 and 95886 billed for the same extremity.

How claims management software supports CPT 95907 billing

For example, many electrodiagnostic practices code 95907 in one system, rekey the claim into a clearinghouse portal, then chase payer status by phone. As a result, each handoff is a chance for the study count or diagnosis to drift away from the signed report.

In contrast, Pabau, the practice management platform we build, keeps the interpretation report, the invoice and the claim on one patient record. In addition, its claims management software turns the invoice into an electronic claim and sends it to thousands of US payers through Claim.MD, our US clearinghouse partner.

Afterward, claim status updates and the electronic remittance advice (835 file) flow back into Pabau. As a result, your team sees which 95907 lines are paid, pending or denied. However, your coder still confirms the study count and diagnosis against the report before the claim goes out.

Conclusion

In conclusion, CPT code 95907 pays cleanly when the study count in the signed report matches the tier on the claim. Therefore, count the studies before you code, and treat any same-session needle EMG as an add-on to the NCS code.

Specifically, three failure points are worth guarding: study-count mismatches, billing 95886 without a qualifying primary NCS code, and ICD-10 codes outside the MAC’s active LCD. Overall, a short check before submission catches each one far more cheaply than an appeal.

Once those checks are routine, Pabau’s revenue cycle management tools keep the claim, its status and the remittance together. Book a demo to see how Pabau supports electrodiagnostic billing from report to remittance.
