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 […]
CPT Code 92250: Fundus Photography Billing Guide
Fundus photography is one of the most frequently performed procedures in ophthalmology and optometry offices across the country. Yet CPT code 92250 remains a persistent source of claim denials, modifier errors, and documentation gaps. Bilateral billing rules, NCCI edit conflicts with OCT codes, and payer-specific medical necessity criteria create enough complexity to trip up even […]
CPT Code 99460: Initial Hospital Newborn Care Billing Guide
Newborn billing errors cost pediatric practices thousands of dollars annually in denied or underpaid claims. The first 24 hours of a normal newborn’s life generate more coding decisions than most providers anticipate: which setting applies, which date of service rules govern the claim, and which diagnosis code pairs correctly. CPT code 99460 sits at the […]
CPT Code 95004: Allergy Skin Test Billing Guide (2026)
Allergy practices lose revenue every week on CPT code 95004, and the pattern is almost always the same: billing per session instead of per allergen, misapplying modifiers, or submitting claims without the ICD-10 codes payers require. The American College of Allergy, Asthma & Immunology (ACAAI) flags per-unit billing errors as one of the most consistent […]
CPT Code 11200: Skin Tag Removal Billing Guide (2026)
Skin tag removal is one of the most frequently miscoded minor procedures in outpatient dermatology and primary care. Claims get denied not because the procedure was wrong, but because the ICD-10 pairing was missing, the modifier was omitted, or the cosmetic vs. medically necessary distinction wasn’t documented before submission. According to CMS Medicare Coverage Article […]
CPT Code 83036: Hemoglobin; Glycosylated (A1c) Billing Guide
Diabetes affects over 38 million Americans, and the hemoglobin A1c test is the cornerstone of managing every one of those patients. Yet CPT code 83036 generates a disproportionate share of claim denials, precisely because billers conflate it with 83037, apply the wrong ICD-10 pairings, or misread the QW modifier rules. A single documentation gap on […]
CPT Code 91010: Esophageal Motility Study Billing Guide
GI motility studies are among the most documentation-sensitive procedures in gastroenterology billing. A missing interpretation report, wrong place-of-service code, or misapplied modifier can turn a covered esophageal manometry claim into a denial. CPT Code 91010 – the code for esophageal motility studies with interpretation and report – requires precise documentation, correct ICD-10 pairing, and an […]
