CPT 93005 Billing: ECG Tracing Only

Mukesh MakwanaFounder & CEO · Hands-on medical billing & RCM across 11 specialties · Reviewed September 28, 2026

CPT 93005 covers the ECG tracing alone, without the interpretation and report. It exists for the situation where one entity runs the machine and a different one reads the result, and almost every 93005 denial comes from billing it when that split did not actually happen.

What CPT 93005 covers

93005 is the routine electrocardiogram with at least 12 leads, tracing only, without interpretation and report. It is the technical half of the service: the equipment, the supplies, the staff time to acquire the tracing.

The ECG family splits through separate codes, not through modifiers:

93000: global, tracing and interpretation by the same practice.
93005: tracing only.
93010: interpretation and report only.

A screening ECG performed as part of the Medicare Initial Preventive Physical Examination is reported with G0404 (tracing only) rather than 93005. G0403 is the global version and G0405 the interpretation-only version.

Reimbursement context

93005 carries the technical value of the service only, so it pays materially less than the global 93000.

2026 Medicare RVUs for CPT 93005

CPT 93005: 2026 Medicare RVUs (national, before GPCI)
Line	Work	PE, non-facility	PE, facility	Malpractice	Total, non-facility	Total, facility
Global (no modifier)	0.00	0.20	NA	0.01	0.21	NA

Source: CMS CY 2026 PFS Relative Value File, RVU26D (October release, published 08/26/2026). RVUs are national and unadjusted; commercial payers set their own rates.

In the 2026 CMS relative value file, CPT 93005 carries 0.00 work RVUs and 0.21 total RVUs. The facility column is NA: CMS values this code only for a non-facility setting such as an office. Its PC/TC indicator is 3: 93005 is itself a technical-component-only code, so modifier TC is never added to it. Its global indicator is XXX: the surgical global period concept does not apply.

To turn RVUs into payment, each component is multiplied by your locality's geographic practice cost index, the three are added, and the sum is multiplied by the 2026 conversion factor: $33.4009, or $33.5675 for qualifying APM participants (CMS-1832-F; CMS fact sheet). The CMS Physician Fee Schedule Look-Up Tool runs that calculation for your locality.

Documentation requirements

A retained 12-lead tracing with date and time.
The clinical indication that prompted the ECG, coded specifically.
The order for the tracing, and who placed it.
Evidence that your entity owned or leased the equipment and supplied the staff.
Identification of where the tracing was sent for interpretation, if applicable.

Medicare contractor billing articles. Each Medicare Administrative Contractor publishes its own billing and coding article for this service, and the covered diagnoses differ by jurisdiction. Active example in the CMS Medicare Coverage Database, checked September 28, 2026: A57326 (Electrocardiograms, Noridian). Use the article from the contractor that processes your claims.

Common denials and the exact fix

Duplicate: 93005 billed alongside 93000

93000 already includes the technical component. Reporting 93005 next to it bills the tracing twice.

Fix: bill one line. If your practice performed and interpreted the tracing, that line is 93000.

Modifier TC appended to 93005

93005 is already technical-only. Adding TC is redundant and some payers reject the line outright.

Fix: submit 93005 with no component modifier.

Under-reporting: 93005 billed when you also interpreted

This one does not deny, which is why it persists. It silently leaves the professional component unbilled on every affected claim.

Fix: audit whether the interpreting physician is in your group. If so, the correct code is 93000, and the gap is worth quantifying across a full quarter.

CO-50: diagnosis does not support the tracing

The technical component is held to the same medical-necessity standard as the global code. A screening diagnosis denies here too.

Fix: carry the ordering physician's cardiac indication onto the claim rather than a generic encounter code.

Second entity already billed the technical component

When a tracing is acquired in one place and repeated or re-billed by another, the second 93005 denies as a duplicate for the date of service.

Fix: confirm no prior technical claim exists for that tracing before resubmitting. A genuine second tracing needs modifier 76 and documentation of why it was repeated.

Modifier rules

TC: not used. 93005 is the technical code by definition.
26: never appropriate on 93005. The professional work is 93010.
76: repeat tracing on the same day, with documentation of the clinical trigger.
59 / XE / XP / XS / XU: rarely applicable; a genuinely separate session is the usual justification, not a bundling workaround.

NCCI bundling edits

93005 with 93000: duplicate technical component, same tracing.
93005 with 93015 or 93017: the resting and stress tracings acquired as part of a stress test are not separately reportable as a routine ECG.
93005 with a same-day E/M: many payers bundle the tracing into the visit. Modifier 25 belongs on the E/M and must be earned.
Facility settings normally bill the technical component through the facility claim rather than through 93005 on a professional claim.

Frequently asked questions

When should I bill CPT 93005 instead of 93000?

Bill 93005 when your practice performed the tracing but did not provide the interpretation and report. If your practice did both, 93000 is the correct global code. Billing 93005 when you also interpreted the tracing under-reports the service and leaves the professional component unbilled.

Do I append modifier TC to CPT 93005?

No. 93005 is already the technical-only code, so appending TC is redundant and can cause a rejection. The ECG family splits through separate codes rather than through 26 and TC modifiers: 93005 for the tracing, 93010 for the interpretation, and 93000 for the global service.

Can 93005 and 93010 be billed for the same tracing?

Yes, but only by different billing entities. 93005 is reported by whoever performed the tracing and 93010 by whoever interpreted it. If a single practice performed and interpreted the tracing, the correct report is one line of 93000 rather than both component codes.

Why did my 93005 claim deny as a duplicate?

The most common cause is 93000 being billed for the same tracing by the same practice, because 93000 already contains the technical component. The other frequent cause is a second entity having already billed 93005 for the same tracing on the same date.
