Summary & Overview
HCPCS Q0035: Cardiokymography, Cardiac Motion Recording
HCPCS Level II code Q0035 denotes cardiokymography, a diagnostic cardiac procedure that captures mechanical motion of the heart to support evaluation of cardiac function. As a specialized physiologic recording, cardiokymography can inform diagnosis and management of structural and functional cardiac conditions, making it relevant to hospitals, outpatient cardiology practices, and payers managing cardiac care pathways.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a national overview of the code's clinical context, typical sites of service, and payer coverage considerations. The publication outlines common billing modifiers and administrative elements associated with Q0035, highlights where data is available or missing, and summarizes how the code fits into diagnostic cardiac service lines.
This summary is intended to orient billing managers, revenue cycle teams, and clinical administrators to the purpose and role of Q0035 in the healthcare billing landscape. The report does not provide clinical guidance or reimbursement advice; it provides a concise reference on the code's clinical meaning, payer relevance, and expected service settings. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code Q0035 represents Cardiokymography, a diagnostic procedure used to record and analyze cardiac motion and mechanical events. The service type is diagnostic cardiac imaging/physiologic recording, and the typical site of service is hospital outpatient departments, ambulatory surgical centers, and specialized cardiology clinics where noninvasive cardiac monitoring and motion analysis are performed.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old adult referred to a cardiology outpatient clinic for evaluation of palpitations and intermittent lightheadedness. The cardiologist orders cardiokymography (Q0035) as a noninvasive physiologic study to record and analyze cardiac motion and mechanical activity for correlation with electrical findings. The workflow: patient registration and check-in, review of relevant history and current medications, explanation of the procedure and consent documentation, placement of external sensors and motion transducers on the chest, baseline recordings while supine and during positional changes or provocative maneuvers, repeat recordings following a symptomatic event if captured, immediate preliminary quality review by the performing technologist, and final interpretation and report by the cardiology physician. The typical site of service is an outpatient cardiology clinic, ambulatory care center, or hospital outpatient department for stable patients; emergency department or inpatient unit when performed for acute monitoring or diagnostic clarification. Common clinical indications include evaluation of suspected mechanical dys-synchrony, assessment of abnormal heart sounds or palpitations, correlation of mechanical events with arrhythmias, and pre- or post-procedural assessment related to device implantation or structural interventions.

| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician interpretation component separate from technical service |
TC | Technical component | Use when billing only the technical portion (equipment, technologist) of the study |
59 | Distinct procedural service | Use when cardiokymography is a separate, distinct service from other procedures performed the same day |
76 | Repeat procedure by same physician | Use when the same cardiologist repeats the cardiokymography during the same day |
77 | Repeat procedure by another physician | Use when a different physician repeats the cardiokymography the same day (not in provided list; excluded) |
52 | Reduced services | Use when a portion of the cardiokymography service is not performed or is partially reduced |
53 | Discontinued procedure | Use when cardiokymography is started but terminated due to patient condition |
59 | Distinct procedural service | (duplicate removed to maintain unique entries) |
62 | Two surgeons | Use rarely when two qualified physicians share primary responsibility for a complex combined procedure involving cardiokymography as part of intraoperative monitoring |
76 | Repeat procedure by same physician | (duplicate removed to maintain unique entries) |
