Billing tips
Bill 93264 only once per 30-day period per patient, regardless of how many transmissions are reviewed
Impact: Prevents automatic denials for duplicate billing; ensures maximum allowable $50.14 monthly reimbursement per patient
Document review of multiple transmissions within the 30-day period, noting specific dates reviewed and clinical decision-making based on trends
Impact: Reduces audit risk and supports medical necessity; insufficient documentation is the leading cause of post-payment recoupment
Ensure the implantable device meets FDA approval for pulmonary artery pressure monitoring and document the device type and serial number
Impact: Required for coverage determination; missing device documentation can result in 100% claim denial
Do not bill 93264 in the same 30-day period as general remote patient monitoring codes (99453, 99454, 99457, 99458)
Impact: Prevents bundling denials; these codes are mutually exclusive and attempting to bill both results in denial of both services
Bill under the NPI of the physician or qualified healthcare professional who personally reviewed the data and made clinical decisions
Impact: Non-physician practitioners can bill under their own NPI at 85% of physician rate ($42.62); billing under wrong NPI creates compliance risk
Verify patient has had device implanted for at least 30 days before billing first monitoring service
Impact: Initial post-implant period is considered part of device implantation global period; premature billing results in denial and potential fraud investigation
Common denials
Frequency limitation - billed more than once per 30-day period
How to appeal: Submit appeal with documentation showing different 30-day periods or correction to billing dates. If legitimately billed for overlapping dates in error, withdraw claim and resubmit with corrected dates. Medicare allows only one unit per 30 days per patient.
Insufficient documentation of clinical decision-making or therapeutic intervention based on monitoring data
How to appeal: Provide complete monitoring report showing dates of transmissions reviewed, hemodynamic trends identified, clinical interpretation, and specific therapeutic changes made (medication adjustments, patient contact). Include evidence that monitoring influenced clinical management, not just passive data collection.
Medical necessity not established - lack of appropriate heart failure diagnosis or device implantation documentation
How to appeal: Submit operative report or implantation record confirming FDA-approved wireless PAP sensor placement, plus documentation of NYHA Class III heart failure diagnosis (ICD-10 I50.x codes). Include clinical notes establishing ongoing need for hemodynamic monitoring.
Bundling denial when billed with other remote monitoring or E/M services on same date
How to appeal: If billed with E/M service, add modifier 25 to E/M code and document separately identifiable service. If denied due to other remote monitoring codes (99453-99458), demonstrate these are mutually exclusive; submit corrected claim removing inappropriate code. Include policy citations showing 93264 is separately reportable.
Frequently asked questions
What is CPT code 93264 used for?
CPT 93264 is used to bill for remote monitoring of an implantable wireless pulmonary artery pressure sensor in heart failure patients. The code covers the physician's monthly review and interpretation of pressure data transmitted wirelessly from the patient's home, including clinical decision-making and therapeutic adjustments based on hemodynamic trends.
How much does Medicare pay for CPT 93264 in 2025?
Medicare pays $50.14 for CPT 93264 in non-facility settings and $33.96 in facility settings under the 2025 Physician Fee Schedule. The code has a work RVU of 0.7 and total RVU of 1.55, based on the conversion factor of 32.3465.
How often can CPT 93264 be billed?
CPT 93264 can be billed only once per 30-day period per patient. Multiple transmissions are reviewed during this period, but the code is reported only once monthly regardless of the number of data reviews performed within that timeframe.
Can CPT 93264 be billed with remote patient monitoring codes?
No, CPT 93264 cannot be billed in the same 30-day period as general remote patient monitoring codes (99453, 99454, 99457, 99458). These codes are mutually exclusive because they represent overlapping services. Bill only the code that most accurately describes the specific monitoring service provided.
What device is associated with CPT 93264?
CPT 93264 is most commonly associated with the CardioMEMS HF System, an FDA-approved wireless implantable hemodynamic monitoring sensor placed in the pulmonary artery. The device measures pulmonary artery pressure and transmits data wirelessly to allow remote monitoring of heart failure patients.
What documentation is required to bill CPT 93264?
Required documentation includes confirmation of implanted FDA-approved wireless PAP sensor, review of multiple transmissions with specific dates, analysis of hemodynamic trends, clinical interpretation, therapeutic interventions or medication adjustments made, and confirmation that 30 days have elapsed since last billing. Documentation must demonstrate active physician engagement in clinical decision-making, not passive data collection.
Can nurse practitioners bill CPT 93264?
Yes, qualified healthcare professionals including nurse practitioners, physician assistants, and clinical nurse specialists can bill CPT 93264 if they have appropriate training in hemodynamic monitoring and heart failure management. Non-physician practitioners typically receive 85% of the physician fee schedule amount ($42.62 for 2025) depending on state scope of practice laws and payer policies.
