CPT Code 78815: PET/CT Billing, Modifiers & Reimbursement

Cpt Code 78815

PET/CT denials are among the costliest in nuclear medicine billing. CPT Code 78815 is one of the most frequently submitted codes for oncologic imaging, yet practices routinely lose reimbursement due to missing documentation, incorrect modifier usage, or misidentified anatomic coverage. Understanding exactly how to bill CPT Code 78815 – from radiopharmaceutical pairing to payer-specific prior […]

CPT Code 25000: Incision of Extensor Tendon Sheath, Wrist

Cpt Code 25000

CPT Code 25000: Definition, Clinical Description, and Code Placement Claim denials for CPT Code 25000 often trace back to a single source: documentation that fails to distinguish between an extensor tendon sheath incision and the single-compartment synovectomy coded under CPT 25118. Hand surgery billing teams that treat these codes as interchangeable can expect payer pushback, […]

CPT Code 13101: Complex Repair Trunk, 2.6-7.5 cm

Cpt Code 13101

Complex wound repair billing is one of the most contested areas in integumentary system coding. A 3 cm trunk laceration requiring undermining and layered closure will qualify for CPT Code 13101, but the documentation in the operative note is what actually determines whether the claim pays. Payers audit this code regularly because the distinction between […]

CPT Code 80053: Comprehensive Metabolic Panel Billing Guide

Cpt Code 80053

CMP claims get denied more often than most lab codes – not because the test isn’t medically necessary, but because documentation doesn’t survive payer scrutiny. A screening ordered at an annual wellness visit without a documented diagnostic indication. A claim bundled with CPT 80048 that triggers an automatic NCCI edit rejection. An ICD-10 code pulled […]

CPT Code 37799: Unlisted Procedure, Vascular Surgery

Cpt Code 37799

Unlisted procedure codes get denied more often than any other code category in vascular surgery billing. The reason is rarely clinical. It comes down to documentation. When a vascular surgeon performs a procedure that has no matching CPT descriptor, the claim for CPT Code 37799 lands on a human reviewer’s desk rather than an automated […]

CPT Code 99601: Home Infusion/Specialty Drug Administration

Cpt Code 99601

Home infusion claims are among the most frequently denied in outpatient billing. Coders misread the 2-hour threshold, forget to append the add-on code for extended visits, or fail to document all time components the NHIA standard includes. One misapplied code can trigger a denial cascade that takes weeks to resolve. CPT Code 99601 covers home […]

CPT Code 50200: Renal Biopsy Percutaneous Billing Guide

Cpt Code 50200

Renal biopsy claims are among the most consistently denied urology procedures in Medicare billing. The reason is rarely clinical: it is almost always a documentation gap, a missing laterality modifier, or an ICD-10 code that does not meet specificity requirements. Practices that understand CPT code 50200 at the billing level, not just the clinical level, […]

CPT Code 58700: Salpingectomy Billing Guide 2026

Cpt Code 58700

Salpingectomy claims generate a disproportionate share of OB/GYN billing denials. The reason is almost always the same: coders use CPT Code 58700 when a different code applies, append modifier 50 when the descriptor already covers bilateral procedures, or pair the wrong ICD-10 diagnosis code with the claim. Each error delays payment and creates audit exposure. […]

CPT Code 20900: Bone Graft, Any Donor Area (Minor or Small)

Cpt Code 20900

Bone graft harvesting denials are more common than most orthopedic coders expect. The separate incision requirement trips up even experienced billers, and payer-specific bundling rules add another layer of complexity. CPT Code 20900 covers a minor bone graft procedure, but billing it correctly depends on documentation that many operative notes simply do not include. This […]

CPT Code 64999

CPT Code 64999 Unlisted Procedure Nervous System

Pain management coders lose reimbursement on CPT Code 64999 not because the claim is wrong, but because the documentation is incomplete. Payers treat unlisted procedure codes differently from standard CPT codes: they require manual review, and without a compelling operative report and a well-constructed cover letter, adjudicators default to denial. According to the American Medical […]
