Is it Chiropractic CPT Code 97014 or 97032 or HCPCS G0283? Understanding This Coding Confusion

[This post was originally published on 10th Oct 2022. It has been updated on 31st March 2026.]

Electrical Muscle Stimulation (EMS) is a widely used therapeutic modality in chiropractic care. Yet billing for it continues to generate claim denials, compliance risks, and revenue losses all because of one core confusion: which code applies to which payer, and when.

This blog cuts through the confusion. It draws directly on the Centers for Medicare & Medicaid Services (CMS) Physician Fee Schedule rules, the National Correct Coding Initiative (NCCI) Policy Manual for Medicare Services and major payer policies to give chiropractors a definitive, up-to-date billing reference.

Part 1: The Three CPT Codes You Need to Know

a) 97014 CPT Code Unattended Electrical Stimulation (Non-Medicare)

Official AMA 97014 CPT code description:  

“Application of a modality to one or more areas; electrical stimulation (unattended).”

CPT 97014 covers unattended electrical stimulation. The provider sets up the equipment and positions the electrodes but does not need to be in the room for the entire session. The provider must remain in the office and be available, but continuous one-on-one patient contact is not necessary. Thus, 97014 code is a supervised modality rather than an attended one.

Key facts about CPT 97014:

• Not a timed service; bill once per session regardless of duration.  
• Bill once per patient encounter, regardless of the number of areas treated.  
• Valid for commercial (non-Medicare) payers; verify each payer’s policy.  
• Invalid for Medicare; CMS Status ‘I’ since March 1, 2003.  
• Optum/UnitedHealthcare require G0283 instead; do not use 97014 for these payers.  
• Incorrect usage can trigger a payer audit. 

b) HCPCS G0283 The Medicare-Required Code for Unattended EMS 

For starters, 97014 is not a valid code when you’re billing Medicare. Chiropractors must use the G0283 procedure code for Medicare patients.

Similarly, if you check the 97014 CPT code reimbursement guideline by Optum, you will find that Optum will not provide reimbursement for 97014. However, unattended electrical stimulation will continue to be a reimbursable service. Providers who use this modality will not receive reimbursement for CPT code 97014. To comply with CMS National Coding Policy, providers should submit the appropriate HCPCS G-code that accurately represents the service provided.

If you check G0283 CPT code reimbursement guidelines by Blue Cross and Blue Shield of Louisiana, the insurance company will apply multiple procedure reductions to codes 95851-95852, 97010-97150, 97169-97596, 97611-97799, 98940-98943 and G0283 when billed on the same day.

Use G0823 for Medicare and not 97014

Official CMS G0283 CPT Code Description:

“Electrical stimulation (unattended), to one or more areas for indication(s) other than wound care, as part of a therapy plan of care.”  

G0283 is the HCPCS Level II code designated by CMS to replace CPT 97014 for Medicare billing. CMS established this code in 2003 to distinguish non-wound-care electrical stimulation from wound-care applications (which use G0281 and G0282).

The Federal Register CY 2025 Physician Fee Schedule Final Rule, published on December 9, 2024, continues to list G0283 alongside 97014 and 97032 under the Physical Medicine and Rehabilitation code set. This confirms it is still the operative Medicare code.  

Key facts about HCPCS G0283:  

• Required for ALL Medicare patients receiving unattended EMS.  
• Also required by UnitedHealthcare and Optum; confirmed by payer policy.  
• Must be billed as part of a documented therapy plan of care.  
• Reimbursement varies by state/locality and facility type per the CMS Physician Fee Schedule.  
• Electrode costs are bundled into G0283; do not bill separately for electrodes under Medicare.  
• CMS applies a 50% Multiple Procedure Payment Reduction (MPPR) on ‘always therapy’ modalities when multiple are billed on the same date.  
• The GP modifier is required when EMS is part of a physical therapy plan of care under outpatient therapy rules. 

c) CPT 97032 Attended Electrical Stimulation 

Official AMA 97032 CPT Code Definition: 

“Application of a modality to one or more areas; electrical stimulation (manual), each 15 minutes.” 

CPT 97032 is fundamentally different from 97014 and G0283. It covers attended electrical stimulation. The qualified provider must maintain direct, one-on-one contact with the patient throughout the session. This is a timed code, billed in 15-minute units. 

It’s appropriate when the provider is actively monitoring and adjusting the stimulation, directing therapeutic exercises, or when the patient needs continuous oversight due to muscle weakness or neurological impairment.

NCCI Edits: What Gets Bundled and Denied

The National Correct Coding Initiative (NCCI) is a CMS program that stops incorrect payments for services that shouldn’t be reported together. The NCCI Policy Manual for Medicare Services updates every year. The current version is effective January 1, 2026, and was posted on December 24, 2025. You can access it at cms.gov.

NCCI edits work through Procedure-to-Procedure (PTP) edits and Medically Unlikely Edits (MUEs). For electrical stimulation billing:

a. PTP Edits

PTP edits create Column 1 and Column 2 code pairs. If both codes from a pair are submitted for the same patient on the same date of service, the Column 1 code gets paid, but the Column 2 code is denied unless a correct NCCI-associated modifier is applied and is clinically supported.  

G0283 is denied when billed with G0151 according to CMS NCCI edits.  

• Some regional payers, like Horizon BCBSNJ, have similar edits denying 97014 when billed with G0151.  
• Blue Cross Blue Shield applies multiple procedure payment cuts to G0283 and codes within the ranges of 95851–95852, 97010–97150, 97169–97596, 97611–97799, and 98940–98943 when billed on the same day.  
• When an NCCI modifier is necessary, the most common ones are 59 (distinct procedural service) and the X-modifiers (XE, XS, XP, XU). Documentation must show that each service is distinct and separate. 

b. Medically Unlikely Edits (MUEs) 

MUEs limit the maximum number of service units that one provider can report for the same patient on the same date. Bill G0283 or 97014 only once per encounter, no matter how many body areas you treated. Exceeding the MUE without proper clinical justification leads to a coding denial, not a medical necessity denial.

Important Note on MUE Denials

A denial tied to an MUE or PTP edit is a coding denial. Under Medicare rules, you cannot use an Advance Beneficiary Notice (ABN) to shift the cost to the patient for services denied due to MUEs or coding mistakes. Correct coding is the only solution.

Part 4: Required Modifiers

Choosing the right modifier is crucial for processing G0283 claims, especially for Medicare patients.

Documentation Requirements

Proper documentation is the key to compliant EMS billing. Incomplete or unclear documentation commonly leads to audits and denied claims. Your SOAP note and plan of care must include:  

• A certified plan of care outlining treatment goals and medical necessity for electrical stimulation.  
• The date of each treatment.  
• The specific method used (e.g., TENS, NMES, EMS) and if it was attended or unattended.  
• The anatomical area(s) treated.  
• Objective proof of medical necessity, such as pain scale ratings, range-of-motion measurements, and muscle strength assessments.  
• Session duration (start and end times), frequency, and intensity parameters.  
• The patient’s response to treatment, including any adverse reactions or changes in tolerance.  
• The effects of electrical stimulation on the patient’s condition.  
• Progress reports, required every 30 treatment days from the start of treatment under Medicare.  
• The identity, signature, and credentials of the qualified provider who delivered or supervised the therapy.

Types of Electrical Stimulation

Understanding which type of electrical stimulation is being applied helps determine the correct code and document the clinical rationale:
