CCSD code 22023 – EMG and nerve conduction studies

Key takeaways

CCSD code 22023 sits in Chapter 3 of the CCSD schedule and covers a combined EMG and nerve conduction study session.

The code applies to mononeuropathy (such as ulnar neuropathy), cervical or lumbar radiculopathy, and myopathy. The documented indication has to match one of those three.

Peripheral neuropathy and carpal tunnel syndrome belong to code 22022. Codes 22024 and 22025 bill the same combined study for a different set of indications.

Most UK private medical insurers require a signed consultant report before they reimburse, and a missing signature is a common cause of rejection.

Pabau, the practice management platform we build, lets neurophysiology teams log CCSD codes, attach clinical reports, and track insurer claim status in one workspace.

CCSD code 22023: Definition and clinical context

CCSD code 22023 is the procedure code for a combined electromyography and nerve conduction study.

It is used in UK private practice to investigate mononeuropathy, cervical or lumbar radiculopathy, or myopathy. It appears in Chapter 3 of the CCSD schedule, the chapter covering spine, spinal cord, and peripheral nerves. The Clinical Coding and Schedule Development (CCSD) group maintains the schedule and updates it annually. Insurers adopt the current edition as the basis for reimbursement decisions.

US CPT codes for EMG run from 95860 to 95872 and are maintained by the American Medical Association. CCSD codes are UK-specific and cannot be swapped for them.

A claim submitted with a CPT code to a UK private medical insurer will be rejected. A CCSD code carries no weight in a US billing context. Both systems cover electrodiagnostic studies through separate coding frameworks.

Where code 22023 sits in the CCSD schedule

Chapter 3 of the CCSD schedule covers interventions for the spine, spinal cord, and peripheral nerves. Within that chapter, the neurophysiological procedures subsection holds the EMG and nerve conduction study family: 22022, 22023, 22024, and 22025. Code 22023 carries the MINOR 5 fee banding, which is the tier insurers price the combined study against.

Clinical indications for CCSD code 22023

CCSD code 22023 covers three distinct clinical indications. Each produces different electrodiagnostic findings, and each has to be named in the formal report for the claim to stand. Coders and billers need to know what the three conditions mean clinically, because the documentation has to reflect the condition under investigation.

Mononeuropathy

Mononeuropathy is damage or dysfunction affecting a single peripheral nerve. The CCSD descriptor gives ulnar neuropathy as the example, and the code also applies to median and peroneal neuropathy.

The nerve conduction study measures conduction velocity and amplitude across the affected segment to localize the site of compression or injury. Needle EMG of the muscles that nerve supplies then confirms the clinical picture.

Cervical and lumbar radiculopathy

Radiculopathy is nerve root dysfunction caused by compression or irritation at the spinal level. Cervical radiculopathy (Cx radiculopathy in the CCSD descriptor) affects the arm and hand, while lumbar radiculopathy affects the leg and foot.

Nerve conduction studies are often normal here, because the lesion sits proximal to the dorsal root ganglion. Needle EMG of the paraspinal and limb muscles in the affected myotome carries more diagnostic weight.

Myopathy

Myopathy is disease of the muscle itself rather than the nerve supplying it. Inflammatory myopathies such as polymyositis and dermatomyositis, along with hereditary myopathies, produce characteristic needle EMG changes.

The report describes short-duration, low-amplitude, polyphasic motor unit potentials with early recruitment. Nerve conduction studies in myopathy are typically normal, so the myopathic pattern in the EMG is what holds the code up under insurer scrutiny.

How the EMG and nerve conduction study is performed

A combined study under CCSD code 22023 runs in two phases. Both are performed by a consultant neurophysiologist or appropriately credentialed specialist, or under their direct supervision.

That expectation follows General Medical Council (GMC) guidance on consultant-led care and British Society for Clinical Neurophysiology (BSCN) practice standards. A study delegated to an unsupervised junior is unlikely to meet insurer requirements for the code.

• Patient preparation: The patient is positioned with the limb at rest and skin temperature above 32°C. Cold limbs slow conduction and produce falsely abnormal results. The consultant explains both components of the test and gains consent.
• Nerve conduction study (NCS): Surface electrodes are placed over the nerve and the recording muscle. A controlled electrical stimulus is applied, and the equipment records conduction velocity, distal latency, and response amplitude. How many nerves are studied depends on the clinical question.
• Needle EMG: A fine concentric needle electrode is inserted into selected muscles. The consultant records spontaneous activity at rest, then motor unit potentials during gentle voluntary contraction, then the recruitment pattern at maximum effort.
• Reporting: Findings from both components are integrated into a single formal report. The report carries a clinical interpretation and a consultant signature. Without both, the claim cannot proceed.

Documentation and reporting requirements

Documentation is where most CCSD code 22023 claims either succeed or fail. Insurers treat the formal written report as the primary evidence of medical necessity.

Insurers also audit claims after payment, and an inconsistent report can trigger a recovery demand long after the episode of care has closed. Structured clinical forms completed at the point of care reduce the risk of an omission reaching the claim.

The elements below make up a complete and valid CCSD code 22023 claim. Requirements vary by insurer, so check the relevant portal before submitting.

• Patient name, date of birth, and insurer membership number
• Referring clinician name and GMC number
• Date the study was performed
• Clinical indication, matching one of the three in the code descriptor
• List of nerves and muscles studied
• Quantitative NCS results (latencies, velocities, amplitudes) with normal ranges
• EMG findings with characterization of motor unit potentials
• Clinical interpretation linking the findings to the diagnosis
• Responsible consultant name, GMC number, and signature (wet or electronic)

Across a busy neurophysiology list, compliance depends on the system prompting the report. The consultant completes and signs it before the invoice is raised, not after.

Which private insurers accept CCSD code 22023?

All major UK private medical insurers use the CCSD schedule for procedure reimbursement, so code 22023 is recognized across the market. Each claim still has to clear that insurer’s own rules, though.

Pre-authorization rules, referral conditions, and documentation standards vary by insurer and by individual policy. Verify the requirements on the insurer portal before the study is booked. For Bupa-specific guidance, see our guide to Bupa CCSD procedure codes.

Fee amounts are not published here, because CCSD fees change annually and differ by insurer. Check the current schedule and your insurer portal for the rate that applies to the MINOR 5 banding.

Related CCSD codes in the neurophysiology family

CCSD code 22023 sits in a group of four closely related neurophysiology codes in Chapter 3. Picking the wrong one is among the more common billing errors in this specialty.

All four share one descriptor, recording and reporting on electromyography and nerve conduction studies (EMG), and differ only by indication. The table below sets out each code. Verify them against the current CCSD technical guide, since descriptors are revised annually.

One question separates these four codes: which indication is under investigation? Each bills the same combined EMG and nerve conduction study, so the condition in the report decides the code. Mononeuritis multiplex, MND-AHC, multiple muscle monitoring and myasthenia gravis without single-fiber EMG go to 22024. Myasthenia gravis with single-fiber EMG goes to 22025.

The pairing to watch is 22022 against 22023, because a neuropathy referral can land under either. Carpal tunnel syndrome and peripheral neuropathy sit with 22022. A single damaged nerve, a compressed cervical or lumbar root, or muscle disease sits with 22023.

Mononeuropathy vs radiculopathy vs myopathy: coding decision guide

All three indications fall under CCSD code 22023, and the documentation still has to show which one was investigated. An insurer auditing the claim checks that the recorded indication matches the electrodiagnostic findings in the report.

The guide below pairs each referral picture with the findings that support it, so the coder can confirm the choice at the point of documentation.

If the referral asks about peripheral neuropathy and the consultant finds an incidental mononeuropathy, document both findings. Code by the primary conclusion the report reaches: 22023 where the focal lesion is the diagnosis, 22022 where the diffuse neuropathy is. Before submitting both codes for one session, confirm with the insurer that unbundling is permitted.

Common billing errors with CCSD code 22023

Rejections of CCSD code 22023 claims follow a small number of recurring patterns. Several of them start in the clinical documentation rather than the billing submission. That is why the whole team needs to recognize them, not only the biller. Insurers return these claims with the same handful of denial codes, so a rejection usually tells you which step failed.

• Missing or unsigned clinical report: A frequent cause of rejection. The report has to be complete and signed by the responsible consultant before the claim is submitted. Electronic signatures are fine where the insurer portal accepts them.
• Wrong indication documented: Submitting 22023 with a report describing peripheral neuropathy will be rejected. The indication on the claim has to match the indication in the report.
• Billing 22023 for another code’s indication: Codes 22024 and 22025 bill the same combined EMG and nerve conduction study. Their indications are mononeuritis multiplex, MND-AHC, multiple muscle monitoring and myasthenia gravis. Claiming 22023 for one of those indications will be returned. So will claiming it when only needle EMG was performed, since the code covers both components.
• Missing pre-authorization: Some insurers require a pre-authorization number before the study takes place. A claim submitted without one is rejected automatically, however good the report is.
• Billing two codes for one session: CCSD code 22023 already covers both the EMG and the nerve conduction components. Submitting 22022 alongside 22023 for the same session reads as unbundling, and it is returned as a duplicate unless the insurer permits it.
• Study performed without consultant involvement: Most insurers decline a claim where no qualified consultant signed the report. Technician-performed studies without consultant supervision and sign-off miss the billing criteria.

How to bill CCSD code 22023 in Pabau

A neurophysiology practice usually keeps the study report in one system, the patient record in another, and the insurer invoice in a spreadsheet. The code then gets copied by hand at each step, which is where indications drift and signatures go missing.

Pabau holds the treatment record, the signed report, and the insurer invoice against the same patient. Our claims software for consultants carries the CCSD code from the treatment record onto the invoice.

The code the consultant recorded is the code the insurer receives. Claim status stays visible in the same place, which shortens the time between the study and the payment.

1. Create the treatment record: When the EMG/NCS session is booked, open a new treatment record for the patient. Add CCSD code 22023 to the procedure field alongside the clinical indication.
2. Attach the clinical report: Once the consultant completes and signs the report, upload it to the patient record. Attaching it before the invoice is raised stops the claim going out without its supporting documentation.
3. Verify insurer details: Confirm the membership number, the policy type, and any pre-authorization number held. These populate the insurer invoice from the patient’s profile.
4. Generate the insurer invoice: Raise the invoice from inside the treatment record. It pulls through the procedure code, the date of service, and the consultant’s details. Review the totals against the insurer fee schedule before sending.
5. Track claim status: The claim tracking dashboard lists outstanding invoices by insurer. Chase each invoice still unpaid after 30 days, quoting the claim reference generated at submission.

Conclusion

CCSD code 22023 is narrower than it looks. It covers a combined EMG and nerve conduction study for three named indications, and the neighboring codes pick up the rest of the neurophysiology list. Get the indication and the signature right and the claim is straightforward. Get either wrong and the claim comes back, however well the study itself was performed.

The practical step is to make the report gate the invoice, so nothing is billed before a consultant has signed off the findings.

Holding the clinical record, the code, and the insurer invoice in one audit-ready system is what makes that routine rather than a monthly chase. Book a demo to see how Pabau handles CCSD coding and insurer claims for a neurophysiology practice.
