CPT code 11901: Intralesional injection billing guide 2026

CPT code 11901 is the procedure code for intralesional injection of a substance into more than 7 distinct lesions in a single patient encounter.

CPT Code 00812: Screening Colonoscopy Anesthesia Guide

CPT Code 00812 is the anesthesia code for screening colonoscopy, reported when the endoscope is introduced distal to the duodenum.

CPT Code 00548: Intrathoracic Anesthesia Billing Guide

CPT code 00548 is billed for anesthesia during thoracotomy or thoracoscopy procedures performed specifically on the trachea and bronchi — not for lobectomy, pneumonectomy, or any other lung resection, and not because one-lung ventilation (OLV) was used. Mixing up 00548 with the family’s dedicated OLV code, 00541, is the most common coding error in this […]
CPT Code 00625: Anesthesia for thoracic spine procedures

CPT code 00625 is one of the more commonly confused codes in thoracic spine anesthesia billing — not because the descriptor is vague, but because it sits between two close siblings, 00620 and 00626. In brief, this guide breaks down exactly what 00625 covers, how its base units and reimbursement are calculated, and how to […]
CPT Code 00211: Anesthesia for craniotomy for hematoma

CPT code 00211 is the anesthesia billing code for craniotomy or craniectomy performed to evacuate a hematoma.

This guide covers the base […]
CPT code 00920: Anesthesia for male genitalia procedures

Anesthesia billing denials rarely stem from the wrong procedure code. More often, a claim for CPT Code 00920 fails because of a missing modifier, a miscounted time unit, or a diagnosis code that doesn’t support medical necessity. The AMA’s CPT code set assigns this code to anesthesia services for male genitalia procedures, including open urethral […]
CPT Code 11313: Shaving of epidermal or dermal lesions billing guide

Dermatology billing staff submit thousands of shave removal claims each year, yet CPT Code 11313 remains one of the more misapplied codes in the 11300 series. Most denials come from one of two places: the wrong anatomic site group, or a lesion diameter that was measured inconsistently or not documented at all. CPT Code 11313 […]
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 […]
