Holter Monitor CPT Code (2022) – Descriptions, Guidelines, Reimbursement, Modifiers & Examples

Holter monitor CPT code(s) 93224-93227 are for services when the physician performs an external electrocardiographic. recording for up to 48 hours by continuous rhythm recording and storage, comprising recording and scanning analysis.

This study evaluates the full-day cycle of a patient’s ambient heart rhythm. The physician suggests the patient use an external electrocardiographic (ECG) recorder, also known as a Holter monitor. 

The technician places ECG leads on the patient’s chest, and the patient wears the recorder for up to 48 hours. During this time, there is continuous rhythm recording and storage.

The patient returns the device, and the recorded heart rhythm is played back into digital format by a technician.

The technician uses a scanning methodology to classify different ECG waveforms and generate a report. The generated report describes the overall rhythm and significant arrhythmias.

Code 93225 reports the recording only, including connection, data recording, and disconnection. Code 93226 bills only the scanning analysis with the report. Code 93227 claims only the provider review and interpretation.

CPT 93224-93227 includes cardiac monitoring using in-person and remote technology for electrocardiographic data assessment. Up to 48 hours of recording continuously

Echocardiography CPT codes (93303-93355, 93356) reports separately in combination with CPT code 93224-93227.

Implantable patient activated cardiac event recorders (93285, 93291, 93297-93298) appropriates to report separately in conjunction with CPT code 93224-93227.

If cardiac monitoring is beyond 48 hours, it is appropriate to report these CPT codes (93241, 93242, 93243, 93244, 93245, 93246, 93247, 93248) instead of CPT 93224-93227.

Holter Monitor CPT Code Examples

The following are the examples when Holter Monitor CPT code(s) 93224-93227 are billed:

Example 1

A 38-year-old male presents to ED with a chief complaint of dizziness. The patient reports vertigo began one day ago. Vertigo began while at home when he stood up.

The patient describes the course of vertigo as abrupt. The dizziness is currently 6/10. Vertigo worsened by standing, head movement, and movement. The vertigo is not worsened by breathing or lying supine. 

Anti-vertigo meds alleviate vertigo. Vertigo is associated with nausea, vomiting, and gait instability. Vertigo is not associated with a vision change.

The patient is morbidly obese ha a higher risk of heart disease. The PhysicianPhysician ordered multiple diagnostic tests ECG, CMP, CBC, CT, MRI, and X-ray of the head and spine.

Diagnostic studies show that patient had an irregular heartbeat and suggested a Holter monitor for two days. 

Example 2

A 30-year-old female with no PMH is coming in for intermittent episodes of chest pain exacerbated by left-arm movement but is non-exertional. 

Differential includes, but is not limited to MSK-related pain/costochondritis/ ACS Pt is very well appearing with routine physical exam and vitals. She is not having any pain right now. Given the positional nature of chest pain, I suspect a musculoskeletal cause. 

The patient was not getting better by medication. Physicians ordered a CT chest and EKG to confirm that the heart was functioning correctly. 

Diagnostic studies show that patient had an irregular heartbeat and suggested a Holter monitor for 24 hours. 

Example 3

Forty-six-year-old female with PMH of hypertension and a family history of heart disease heart murmur, LBBB dx 1 year ago, migraines, tested positive for COVID 1 month ago. 

Since yesterday afternoon, she was presented to ED c/o constant lip-tingling, lightheadedness, and left-sided chest discomfort. She woke morning with the same symptoms, and she also developed left upper extremity tingling and bilateral hand tingling. The patient is not vaccinated for COVID. 

The patient Denies headache, shortness of breath, back pain, abdominal pain, nausea, vomiting, diarrhea, changes in vision, urinary complaints, or any other symptoms. 

The patient has a family history of heart diseases—the physician plan to do labs, EKG, X-ray, CT, and MRI of the chest.

Diagnostic studies show that patient had an irregular heartbeat and suggested a Holter monitor for 24 hours.

Example 4

A 27-year-old male with PMH Systolic/Diastolic CHF (EF <15% 7/23/21, s/p AICD), COVID x2, s/p TAVR, CAD, CKD, PAD, hypothyroidism for shortness of breath. He has developed progressively worsening shortness of breath for four days. 

He noticed worsening SOB laying on his right side and with exertion. He takes his vitals daily and weighs himself daily; he typically weighs 171lbs but has seen a 3.5lb increase in his weight to 174.5lbs over this past week, which prompted him to take one dose of alprazolam 30mg.

He noticed a minimal improvement in his symptoms with the alprazolam. 

When he has episodes of coughing with phlegm, he notices a substernal discomfort. The discomfort is not alleviated with rest and not exacerbated with exertion. He has also noticed increasing yellow phlegm production, cough, nasal congestion, and rhinorrhea. 

The PhysicianPhysician has respiratory problems along with Heart issues. Diagnostic studies show that patient had an irregular heartbeat and suggested a Holter monitor for 24 hours.

The PhysicianPhysician ordered EKG, Labs, CT, and MRI to diagnose for further treatment.

Example 5

A 39-year-old female presented office for dizziness, weakness, and tingling in the upper extremity. The patient denies any abdominal pain, diarrhea, vomiting, or headache in the system review. 

Physical exam revealed that the patient had an irregular heartbeat, shortness of breath, and fluid accumulation in the upper extremity, more likely edema.

A physical exam strongly suggests ruling out heart-related diseases. The physician decides to do ECG/EKG, CTA, and MRA of the chest. 

EKG revealed that the patient is tachycardic. Diagnostic studies show that patient had an irregular heartbeat and suggested a Holter monitor for 24 hours. The physician has consulted with the cardiologist for further treatment of the patient.
