CPT Code 99255: Inpatient Consultation, Level 5 Billing Guide
Most consultation denials are not caused by incorrect code selection. They happen because the supporting documentation fails to justify the level billed. For CPT Code 99255, the highest-level inpatient or observation consultation in the active range, the gap between what a consulting physician actually did and what the medical record proves can cost thousands in […]
CPT Code 99395: Preventive Visit Billing Guide for Ages 18-39
Preventive visits are among the most audited and most denied claim types in outpatient primary care. CPT Code 99395 is the correct code for a comprehensive preventive medicine reevaluation of an established patient between 18 and 39 years old, but incorrect modifier usage, missing ICD-10 pairing, and age-range errors cause a disproportionate share of rejections. […]
CPT Code 33285: Insertion, Subcutaneous Cardiac Rhythm Monitor
CPT Code 33285: Definition and Clinical Description Cardiology billing specialists see CPT Code 33285 denied more often than almost any other device implantation code, and the root cause is nearly always the same: missing or incomplete documentation of medical necessity. The code was added to the American Medical Association’s CPT code set in 2019 as […]
CPT Code 76604: Chest Ultrasound Billing Guide
CPT Code 76604: Definition and Clinical Description Chest ultrasound denials are rarely about the procedure itself. They are almost always about what the documentation says – or fails to say. CPT code 76604 is the designated billing code for an ultrasound examination of the chest including the mediastinum, performed in real time with image documentation. […]
CPT Code 92015: Determination of Refractive State
Refraction claims are among the most commonly denied in eye care billing. Practices bill CPT Code 92015, assume standard coverage applies, and then receive zero reimbursement from Medicare and a flat bundling rejection from Humana. This happens not because the service was undocumented, but because the coverage rules for refraction differ dramatically from payer to […]
CPT Code 27599: Unlisted Procedure, Femur or Knee
Unlisted procedure codes trip up orthopedic billing teams more often than any other code category. When a surgeon performs a novel or rarely codified knee procedure, there is no default CPT code to reach for, and submitting without the right documentation almost guarantees a denial. CPT Code 27599 exists precisely for this gap, but using […]
CPT Code 77001: Fluoroscopic Guidance for Central Venous Access
Claim denials for fluoroscopy guidance codes rank among the most preventable errors in interventional radiology and vascular surgery billing. CPT Code 77001 is an add-on code with specific qualifying procedures, bundling restrictions, and documentation mandates that, when misapplied, result in rejected claims or compliance exposure. This reference covers the official descriptor, add-on code requirements, NCCI […]
CPT Code 55250: Vasectomy Billing, Modifiers & Reimbursement
Vasectomy claims are among the most frequently miscoded procedures in urology billing. The most common error is not the code itself – most billers know CPT Code 55250 – it’s the diagnosis code, the modifier, and whether post-procedure semen analysis is bundled or separately billable. Each of these mistakes triggers a denial or a payer […]
CPT Code 20680: Removal of Implant; Deep
Claims for surgical hardware removal get denied more often than coders expect. The most common reason is a mismatch between the operative report and the code selected: the physician documents a deep procedure, but the claim goes out under the superficial code, or vice versa. CPT Code 20680 is the correct code when a surgeon […]
CPT Code 56605: Biopsy of Vulva or Perineum, One Lesion
Vulvar biopsy claims are among the most frequently denied gynecology procedures, often due to missing modifiers, mislinked diagnosis codes, or inadequate procedural documentation. CPT Code 56605 covers biopsy of the vulva or perineum for a single lesion, and getting the billing right requires more than just knowing the code number. This guide covers the official […]
