Ext ecg>7d<15d rec scan a/r
CPT 93245 covers the professional work of scanning and analyzing recordings from a heart monitor that a patient wore continuously for 7 to 15 days. This code is used when the physician reviews the recorded data and provides an interpretation report.

Billing tips
Verify and document the exact monitoring duration in days and hours. CPT 93245 requires >7 days but <15 days of recording. If monitoring is 7 days or less, use 93227-93229 instead; if 15+ days, use 93247-93248.
Impact: Incorrect code selection based on duration results in automatic denials or downcoding, potentially losing $100+ in reimbursement
Bill 93245 only once per monitoring period, regardless of how many times the data is accessed. This is a global interpretation code that encompasses the entire analysis and reporting for the full recording period.
Impact: Duplicate billing attempts result in denials and potential audit flags; ensure only one unit billed per complete monitoring episode
Do not bill 93245 with the hookup code (93241) or recording code (93243) on the same date if you're using the same monitoring system. These are bundled services when performed by the same provider.
Impact: Unbundling violations trigger NCCI edits resulting in automatic denial of the secondary code, plus potential recovery audits
Ensure the interpretation report explicitly states total monitoring duration, percentage of analyzable data, rhythm findings throughout the entire period, correlation with patient symptom diary, and clinical conclusions.
Impact: Incomplete documentation is the #1 audit vulnerability; comprehensive reports reduce appeal timeframes and support the full $270.42 payment
Verify patient symptom diary completion before finalizing interpretation. Medicare and most commercial payers expect correlation between recorded events and patient-reported symptoms in the documentation.
Impact: Missing symptom correlation can result in medical necessity denials; proper documentation supports the 8.36 total RVUs claimed
For Medicare patients, confirm the monitoring was ordered with appropriate diagnosis codes supporting medical necessity (syncope, palpitations, arrhythmia surveillance). Pre-authorization may be required by some Medicare Advantage plans.
Impact: Medical necessity denials can result in complete non-payment of $270.42; prior authorization violations may make the service non-billable to patient
Common denials
Monitoring duration not clearly documented or falls outside 7-15 day window required for 93245
How to appeal: Submit detailed records showing exact start date/time and end date/time of monitoring with device logs. If duration was actually 7-15 days, provide device data export showing continuous recording. If duration was different, submit corrected claim with appropriate code (93227 for ≤7 days or 93247 for ≥15 days).
Medical necessity not established - payer deems standard Holter monitoring should have been attempted first
How to appeal: Provide documentation of previous non-diagnostic shorter-duration monitoring or clinical justification for why extended monitoring was initially necessary. Include records of symptom frequency indicating events occur less than weekly, requiring extended surveillance period.
Duplicate billing or frequency limitation exceeded - monitoring repeated too soon without documented clinical reason
How to appeal: Submit clinical documentation explaining new symptoms, change in condition, post-intervention surveillance, or other medical necessity for repeat monitoring. Include comparative interpretation showing different clinical question or interval change in patient status.
NCCI edit denial when billed with hookup code 93241 or other monitoring codes from same family by same provider
How to appeal: Review claim for unbundling errors. If services were truly separate and distinct (different dates, different monitoring periods), provide documentation with clear timeline. More commonly, resubmit corrected claim removing the bundled code. If different providers performed different components, ensure each provider bills only their component with appropriate modifiers.
Frequently asked questions
What is the difference between CPT 93245 and 93227?
CPT 93245 is used for scanning and interpreting extended ECG recordings lasting more than 7 days but less than 15 days, while 93227 covers recordings up to 48 hours. The duration of continuous monitoring determines which code to use. Both have the same 2025 Medicare rate of $270.42, but 93245 has higher RVUs (8.36 vs 7.83) reflecting the greater volume of data to review.
How much does Medicare pay for CPT 93245 in 2025?
Medicare pays $270.42 for CPT 93245 in 2025 based on the national average non-facility rate. This rate is the same for both facility and non-facility settings. The payment is calculated from 8.36 total RVUs multiplied by the 2025 conversion factor of 32.3465.
Can CPT 93245 be billed with modifier 26?
CPT 93245 already represents professional component work (interpretation and report), so modifier 26 is typically not appropriate. The code describes only the scanning, analysis, and reporting - not the technical hookup or recording. If you need to indicate split billing, verify your practice's arrangement and whether you're using the global code or should be using separate technical/professional codes.
How often can CPT 93245 be billed for the same patient?
CPT 93245 should be billed once per completed monitoring period. Frequency for repeat monitoring periods varies by payer but typically requires documentation of new symptoms, change in clinical status, or specific medical necessity. Most payers allow repeat monitoring after several months if clinically indicated, but repeating within 30 days often triggers review.
What diagnosis codes support medical necessity for CPT 93245?
Common supporting diagnoses include R55 (syncope), R00.2 (palpitations), I48.0-I48.2 (atrial fibrillation), I49.01-I49.9 (other arrhythmias), I47.0-I47.9 (paroxysmal tachycardia), and Z95.0 (post-cardiac device placement). The key is documenting why extended 7-15 day monitoring is necessary rather than standard shorter-duration monitoring.
What are the RVUs for CPT code 93245?
CPT 93245 has 8.36 total RVUs in 2025, consisting of 0.55 work RVUs, 7.77 practice expense RVUs (both facility and non-facility), and 0.04 malpractice RVUs. The practice expense component represents the majority of the RVU value, reflecting the equipment and technical resources required for extended monitoring data management.
Can CPT 93245 be billed with other cardiac monitoring codes?
CPT 93245 should not be billed with other codes from the same monitoring episode (93241, 93243 from same provider/period). It can be billed separately from different monitoring modalities (like event monitors or implantable loop recorders) performed during different time periods. Review NCCI edits carefully as many cardiac diagnostic codes have bundling restrictions.
