- — This clinical order protocol is designed for referring primary care physicians, orthopedists, endocrinologists, neurologists, and general practitioners in Northern Luzon.
- — An EMG-NCV is a highly dynamic, physician-conducted procedure, not a static automated test; clinical history from the referring physician is critical to target the study.
- — Standard clinical indications include suspected radiculopathy, distal nerve entrapments, diabetic peripheral neuropathy, plexopathy, and unexplained focal muscle weakness.
- — We provide comprehensive diagnostic reports immediately following the study, enabling referring clinics to implement therapeutic interventions without delays.
- — We coordinate closely with regional clinics to streamline HMO pre-authorizations and document PhilHealth clinical eligibility criteria.
In the modern, collaborative healthcare landscape of Northern Luzon, delivering rapid and highly precise diagnostic answers is the cornerstone of successful clinical outcomes. When a patient presents to your clinic with complex neuromuscular symptoms—such as radiating limb pain, persistent distal numbness, progressive muscle weakness, or a sudden loss of fine motor coordination—pinpointing the exact anatomical source of the pathology is the first and most critical step in establishing a definitive treatment plan.
An electrodiagnostic study is not a simple, automated laboratory test that can be run on a generic template. It is a highly operator-dependent, dynamic, and interactive medical procedure. The accuracy and diagnostic yield of an EMG NCV test rely entirely on the clinical coordination between the referring physician and the board-certified specialist performing the study.
This B2B clinical guide is designed to assist our regional medical partners—including family physicians, internists, orthopedists, neurosurgeons, endocrinologists, rheumatologists, and physical therapists—in writing precise, highly targeted diagnostic orders, understanding medical clearance protocols, and streamlining HMO and PhilHealth documentation.
Core Clinical Indications: Standard Diagnostic Ordering Guidelines
To ensure the highest clinical efficacy, an EMG-NCV study should be ordered to evaluate specific, objective neuromuscular pathologies.
We recommend ordering an electrodiagnostic study under the following clinical scenarios:
| Clinical Presentation | Suspected Pathology | Common ICD-10 Code | Electrodiagnostic Value |
|---|---|---|---|
| Radiating neck pain, arm weakness, dermatomal numbness. | Cervical Radiculopathy (Herniated disc or osteophyte). | M54.16 | Needle EMG confirms active root compression and isolates the exact spinal level (C5-C8). |
| Radiating lower back pain, sciatica, shooting leg pain. | Lumbar Radiculopathy (L4, L5, S1 root compression). | M54.16 | Differentiates spinal root compression from peripheral peroneal or tibial nerve lesions. |
| Nocturnal hand numbness, clumsy fingers, dropping objects. | Carpal Tunnel Syndrome (Median nerve compression at the wrist). | G56.00 | NCV calculates the exact terminal latency and conduction drop across the wrist. |
| Pinky finger numbness, funny bone pain, weak grip. | Cubital Tunnel Syndrome (Ulnar neuropathy at the elbow). | G56.20 | Isolates elbow-conduction velocity drop using the segmental inching stimulation method. |
| Symmetrical stocking-glove tingling, burning feet in diabetics. | Systemic Polyneuropathy (Metabolic, toxic, or inflammatory). | E11.40 / G60.9 | NCV quantifies sensory and motor axon loss and differentiates axonal vs. demyelinating pathology. |
The Standard Referral Order: A Clinical Template
When writing a diagnostic referral for an EMG-NCV study, providing clear clinical details allows Dr. Rabara to tailor the electrodiagnostic examination dynamically. Unlike standard lab tests, Dr. Rabara customizes the nerves stimulated and muscles needled in real-time based on the clinical question.
We recommend using the following standard template for your referral orders:
Recommended Referral Order Format
Patient Name: [Patient's Full Name]
Date of Birth: [DOB] | Age / Sex: [Age/Sex]
HMO / Insurance Provider: [HMO Name] (for pre-auth coordination)
Diagnostic Order Request:
[ ] EMG-NCV Upper Extremities (Left / Right / Bilateral)
[ ] EMG-NCV Lower Extremities (Left / Right / Bilateral)
[ ] Focused Single-Limb Nerve Conduction Velocity (NCV) Only
Clinical Indications & Symptoms:
- Primary Complaint: [e.g., Radiating arm pain to middle finger, foot drop, hand numbness]
- Duration: [e.g., 6 weeks, chronic metabolic]
- Key Physical Signs: [e.g., Diminished triceps reflex, grip weakness, positive Tinel's at wrist]
Differential Diagnosis / Clinical Question:
- Rule out: [e.g., Cervical radiculopathy vs. Median Neuropathy at the wrist]
Critical Safety Disclosures:
- Cardiac Pacemaker or Defibrillator: [Yes / No]
- Anticoagulant Therapy (e.g., Warfarin, Eliquis, Plavix): [Yes / No]
Pre-Test Patient Instructions: Handout for Referring Clinics
To ensure patient comfort and prevent diagnostic interference, please advise your patients of the following simple preparation steps on the day of their appointment:
- Skin Hygiene (Critical): Advise the patient to wash their arms and legs thoroughly with soap and water to remove natural skin oils. They must NOT apply any body lotions, moisturizers, creams, or oils on the day of the test, as these substances create an electrical barrier that blocks our sensitive recording electrodes.
- Dress Comfortably: Patients should wear loose-fitting, comfortable clothing. For upper limb studies, a sleeveless shirt or loose t-shirt is ideal. For lower limb studies, loose shorts or pants that can be easily rolled up above the knee are recommended.
- Medication Compliance: Patients should take all of their usual daily medications (including blood pressure, thyroid, and diabetic medications) normally. Note: If the patient is taking Mestinon (pyridostigmine) for Myasthenia Gravis, they should consult their neurologist, as this medication must often be held for 12 to 24 hours before a repetitive nerve stimulation study.
- No Prior Fasting: There are absolutely no dietary restrictions. Patients can eat, drink, and go about their normal activities before and immediately after the test.
HMO Pre-Authorization and PhilHealth Compliance
At TeraCare Vigan, we recognize that navigating medical insurance can be stressful for patients. We coordinate closely with your billing staff to streamline the administrative process:
- Comprehensive HMO Coverage: TeraCare Clinic is an accredited diagnostic provider for major national Health Maintenance Organizations (HMOs) in the Philippines. We accept pre-authorized referrals, helping patients minimize out-of-pocket expenses.
- PhilHealth Accreditation: Dr. Ben Paolo C. Rabara is a fully accredited PhilHealth provider. For inpatient or qualified outpatient diagnostic protocols, we document and compile all necessary clinical eligibility criteria (including PhilHealth CF1 and CF2 forms) to ensure seamless benefit claims.
- Direct Patient Coordination: Once your clinic issues the referral order, our dedicated administrative team contacts the patient directly to schedule their appointment, verify their insurance benefits, and handle all pre-authorization paperwork, saving your staff valuable time.
The Collaborative Promise: Same-Day Diagnostic Partnership
As Physical Medicine & Rehabilitation (PM&R) specialists, our ultimate clinical goal is functional restoration and seamless continuity of care.
When you refer a patient to Dr. Ben Paolo Rabara for an EMG-NCV study, we make the following commitments to your clinic:
- Immediate Report Turnaround: You will never have to wait days or weeks for lab results. The final, comprehensive electrodiagnostic report—complete with numerical conduction velocity tables, muscle needle analysis, and clinical interpretations—is handed directly to the patient to bring back to your office immediately.
- Open Communication Pathways: If Dr. Rabara identifies an acute, severe neurological emergency (such as a severe spinal compression threatening immediate bowel/bladder dysfunction or acute, progressive motor axon loss), he will contact you directly via phone or secure messaging to coordinate immediate intervention.
- Collaborative Non-Surgical Treatment Plans: We respect your role as the primary coordinating physician. Our reports do not just state a diagnosis; they outline targeted physical therapy, non-surgical mechanical traction, or local injection recommendations that you can implement immediately within your own practice.
