CPT 93244 covers the physician's review and interpretation of an extended heart rhythm recording that runs continuously for more than 48 hours but less than 7 days. This is the professional component where the cardiologist analyzes the data and writes a report.

Billing tips
Verify the exact duration of monitoring in the device report before code selection. 93244 requires >48 hours but <7 days; if monitoring was 48 hours or less, use 93227 instead, or if 7+ days, use different extended monitoring codes.
Impact: Incorrect duration coding results in 80%+ denial rate. Proper code selection ensures the $22 reimbursement versus potential denials or downcoding.
Document the total analyzable recording time, not just the patient wear time. If significant data loss occurred due to lead disconnection, note the analyzable hours and consider modifier 52 if below threshold.
Impact: Payers may deny if analyzable time falls below 48 hours. Clear documentation of 50+ hours of clean data supports full payment and reduces audit risk by 60%.
Do not unbundle 93244 with the same-day technical component codes (93241). Bill globally if your practice provided both equipment and interpretation, or use modifier 26 if interpreting for another provider's equipment.
Impact: Unbundling violations trigger automatic denials and potential recoupment. Correct modifier use prevents $22-$50 in overpayment recovery per claim.
Ensure the interpretation report includes mandatory elements: total recording time, rhythm analysis, arrhythmia quantification, symptom-rhythm correlation from patient diary, and clinical impression with recommendations.
Impact: Missing any required element increases audit vulnerability by 40% and can result in full recoupment of the $22 payment plus potential False Claims Act exposure for repeat violations.
Bill 93244 only once per continuous monitoring session, regardless of how many times you review the data. Multiple reviews of the same recording period do not support multiple claims.
Impact: Duplicate billing results in 100% denial of second claim plus potential fraud investigation. One monitoring session = one interpretation code, protecting the practice from compliance issues.
Coordinate billing with the device company if they bill the technical component. Obtain verification that they are billing 93241-TC to avoid duplicate global billing that triggers payer edits.
Impact: Uncoordinated billing creates 50%+ denial rate on professional component claims. Pre-billing coordination ensures clean $22 payment within 30 days.
Common denials
Medical necessity not established - payer states insufficient documentation of indication for extended monitoring versus standard 24-48 hour Holter.
How to appeal: Submit appeal with clinical notes documenting infrequent symptoms (occurring less than daily), failed shorter-duration monitoring, or specific clinical guidelines recommending extended monitoring for the patient's condition (e.g., cryptogenic stroke workup, paroxysmal AFib detection). Include patient symptom diary showing events beyond 48-hour window.
Incorrect code for duration - monitoring was 48 hours or less, requiring 93227 instead of 93244, or exceeded 7 days requiring different code set.
How to appeal: Review the device-generated report for exact start/stop times. If actual analyzable time was >48 hours to <7 days, submit corrected claim with device report highlighting timestamp data. If monitoring truly was ≤48 hours, void the original claim and resubmit with correct code 93227.
Bundling denial - payer states 93244 is included in a separate E/M service or bundled with technical component already paid.
How to appeal: For E/M bundling denials, document that interpretation occurred on separate date from E/M or that services were distinct and separately identifiable. For technical component bundling, verify whether practice billed global code versus 26 modifier for professional component only. Resubmit with correct modifier if needed.
Duplicate service denial - payer records show same monitoring period already paid, or multiple interpretation codes billed for single monitoring session.
How to appeal: Review claim history to confirm no previous payment for this specific date range. If patient had multiple separate monitoring periods (different date ranges), submit appeal with both device reports showing distinct start/stop dates. If truly duplicate, void the second claim and implement billing controls to prevent future occurrences.
Frequently asked questions
What is the difference between CPT 93244 and 93227?
CPT 93227 covers ECG monitoring for up to 48 hours with interpretation, while 93244 covers interpretation of monitoring that exceeds 48 hours but is less than 7 days. The key distinction is duration: use 93227 for 24-48 hour Holter monitors and 93244 for 3-7 day extended patch monitors or extended Holter studies. The 2025 Medicare payment for 93244 is $22.
How much does Medicare pay for CPT code 93244 in 2025?
The 2025 Medicare national average reimbursement for CPT 93244 is $22 for both facility and non-facility settings. This is based on 0.68 total RVUs (0.5 work RVU + 0.16 practice expense RVU + 0.02 malpractice RVU) multiplied by the 2025 conversion factor of 32.3465. Actual payment may vary by geographic locality.
Can I bill 93244 with modifier 26 for interpretation only?
Yes, if you are only interpreting the ECG data and did not provide the monitoring equipment or recording services, append modifier 26 to indicate you are billing the professional component only. The device company or facility would separately bill the technical component (93241-TC). Verify with the technical service provider to avoid duplicate billing of the global service.
What documentation is required to bill CPT 93244?
Your interpretation report must include: total monitoring duration with exact dates/times, total analyzable recording time, predominant rhythm, quantification of all arrhythmias (PVCs, PACs, runs, pauses), correlation of patient symptoms from diary with ECG at those times, clinical interpretation, and management recommendations. The physician must sign and date the report. Missing elements increase audit risk and denial probability.
How many times can I bill 93244 for the same patient?
You can bill 93244 once per continuous monitoring session. If the patient has multiple separate monitoring periods (different date ranges, separate orders), each session can be billed separately. However, you cannot bill multiple 93244 codes for reviewing the same data set multiple times or for one continuous monitoring period, even if it generates multiple reports.
What are the RVUs for CPT code 93244?
CPT 93244 has 0.5 work RVUs, 0.16 practice expense RVUs (both facility and non-facility), and 0.02 malpractice RVUs, totaling 0.68 RVUs. These are the 2025 CMS Medicare Physician Fee Schedule values released in December 2024. The relatively low RVU reflects that this is primarily a cognitive interpretive service without significant procedural work.
What is the most common denial reason for CPT 93244?
The most common denial is incorrect duration coding—billing 93244 when monitoring was actually 48 hours or less (should be 93227) or when exact monitoring hours are not documented in the interpretation report. To prevent this, always verify the device-generated report shows >48 hours but <7 days of recording time and document the exact duration in your interpretation. This single issue accounts for approximately 40% of 93244 denials.
