CPT Code 11441: Benign lesion excision on face and ears
Claim denials for benign skin lesion excisions often trace back to one avoidable error: the biller used the visible lesion size rather than the excised specimen diameter. For CPT Code 11441, that distinction determines whether the claim is paid at all. The code covers facial-site excisions in the 0.6 to 1.0 cm excised diameter range, […]
CPT Code 11301: Shaving of epidermal or dermal lesion
CPT Code 11301: definition and clinical description Dermatology billers submit claims for lesion removal every day, yet the 11300 code family generates a disproportionate share of denials. Size thresholds, anatomical site restrictions, and the shaving-versus-excision distinction catch coders off guard more often than almost any other procedure group. CPT Code 11301 is the code for […]
CPT Code 11104: Punch biopsy of skin, single lesion
CPT Code 11104: Definition and procedure overview CPT Code 11104 is a billable code for a punch biopsy of the skin, first lesion, including simple closure when performed.

CPT Code 10120: Incision and removal of foreign body, subcutaneous tissues
Foreign body removal sounds straightforward. In practice, it is one of the most frequently miscoded minor procedures in outpatient and urgent care settings. CPT Code 10120 covers the simple version of this procedure, but the line between “simple” and “complicated” is where most billing errors occur. Getting that distinction wrong exposes practices to upcoding audits […]
CPT code 00866: Adrenalectomy anesthesia billing guide
CPT code 00866 is the anesthesia code for an adrenalectomy, open or laparoscopic removal of one or both adrenal glands.

Its base unit value is 10, among the highest in that […]
CPT Code 00144: Eye Procedure Anesthesia Billing Guide
Anesthesia claims for corneal transplant surgery are billed under a single, specific CPT code: 00144. Despite sitting inside the eye anesthesia family (00140-00148), CPT 00144 is not a catch-all or fallback code — it has its own official descriptor, its own ASA base unit value, and its own set of supporting ICD-10 diagnoses tied to […]

CPT Code 10009: Fine needle aspiration biopsy with CT guidance
CPT Code 10009 describes fine needle aspiration (FNA) biopsy with CT guidance for the first lesion in a session. Most FNA billing denials trace back to one of two errors: separately billing the imaging guidance that’s already bundled into the code, or reaching for the wrong code in the 10004-10012 series when the imaging modality […]
