CPT 93923: 2026 Billing, Documentation, Medicare Coverage and Denial Prevention
CPT 93923 reports a complete, bilateral physiologic study of the upper or lower extremity arteries. The study must cover three or more levels, or include a qualifying provocative maneuver, to count as complete.

CPT Code 93925: 2026 Billing, Documentation and Reimbursement Guide
The 93925 CPT code reports a complete bilateral duplex scan of the lower-extremity arteries or arterial bypass grafts. The study combines structural imaging with blood-flow analysis and covers both legs in the same session.

CPT 93922: ABI Billing, Documentation and Reimbursement Guide
CPT 93922 reports a limited, bilateral, noninvasive physiologic study of the arteries in the arms or legs, usually performed at one or two testing levels. A lower-extremity study commonly pairs ankle-brachial index measurements with a second qualifying test, such as Doppler waveform recording, volume plethysmography, or transcutaneous oxygen measurement.

93971 CPT Code: 2026 Billing, Documentation, Modifiers and Denial Prevention
The 93971 CPT code looks like one of the simpler entries in a vascular ultrasound fee schedule. Payment problems start when study scope, documented laterality, medical necessity, and the diagnosis code on the claim tell different stories. Confusion with the neighboring bilateral code is the biggest source of code-selection risk on extremity venous duplex claims. […]
93970 CPT Code: Complete Billing and Documentation Guide
CPT 93970 reports a complete bilateral duplex examination of the extremity veins, covering paired upper or lower extremities. The study combines structural imaging with blood-flow analysis, and compression or other documented maneuvers confirm the findings. Code selection has to match the examination performed and documented, not the exam that was originally ordered. Practices often search […]
Account Receivable in Medical Billing: The 2026 Guide for Healthcare Providers
Your practice earned the money weeks ago. The visit happened. The claim went out. The cash still isn’t in your account, and that gap between earned and collected is where revenue slips away.

99495 CPT Code: 2026 TCM Billing Rules, Documentation, and Denial Prevention
Your team saw the patient after a hospital discharge, documented the visit, and sent the claim. The denial came back anyway.

The code pays for Transitional Care Management (TCM), a 30-day service that starts the day a patient leaves […]

What Is CPT Code 78452, and Which Modality Does It Cover CPT code 78452 reports myocardial perfusion imaging using SPECT technology, performed as multiple studies, both rest and stress, to evaluate blood flow to the heart muscle and identify areas of reduced perfusion.

CPT Code 99401 Billing Guide: Documentation, Medicare Rules, Modifiers, and Denials
Why CPT 99401 Is Harder to Bill Than It Looks A provider who orders preventive counseling usually knows the visit involved risk factor reduction, not treatment of an active illness. The 99401 cpt code itself is not the hard part. What is hard is whether the payer accepts it, whether the note proves a separate […]
Stress Test CPT Codes: The 2026 Billing Guide for Exercise, Echo, and Nuclear Cardiac Testing
What Is a Cardiac Stress Test, and Which CPT Code Applies to Each Type Stress test CPT codes fall into three distinct families, depending on how the heart is stressed and what the team measures: exercise or pharmacologic ECG monitoring under 93015 through 93018, stress echocardiography under 93350 through 93352, and nuclear myocardial perfusion imaging […]
