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. It sits in the 00800-00882 lower-abdomen range alongside several urology codes, though it isn’t a urology code itself, and no surgeon bills it directly. 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 00160: Anesthesia for nose and sinus procedures
CPT Code 00160 is the anesthesia code for procedures on the nose and accessory sinuses, not otherwise specified (NOS), billed at 5 base units.

CPT code 01966: Anesthesia for induced abortion procedures
Official AMA descriptor: Anesthesia for induced abortion procedures. CPT code 01966 sits within the Anesthesia for Obstetric Procedures subsection (codes 01958-01969) of the AMA CPT code set.

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 […]
CPT code 00864: Cystectomy anesthesia billing guide
CPT code 00864 is the anesthesia code for extraperitoneal procedures in the lower abdomen, including the urinary tract and total cystectomy (bladder removal). It carries 8 base units under the ASA Relative Value Guide, one of the higher values in the 00800–00882 family. That is why the base unit count is often the first thing […]
CPT code 10004: Add-on code for each additional FNA lesion
CPT 10004 is the add-on code for each additional FNA lesion without imaging – always billed with primary code 10021, never alone.

Per the AMA’s CPT code set, this code falls within the Anesthesia for Obstetric Procedures section (range 01958 through 01969).
