CPT 42104 Reimbursement & Policy Benchmarks

CPT code 42104 denotes excision of a lesion from the palate or uvula without closure. The code captures a focused, limited soft-tissue surgical procedure in the oropharynx and is used across ambulatory surgical centers, hospital outpatient departments, and some office-based surgical settings. It matters nationally because accurate coding supports appropriate clinical documentation, procedure tracking, and payment for targeted oropharyngeal lesion removal.

Key payers in typical coverage analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. These payers commonly assess medical necessity, place-of-service, and documentation of lesion characteristics to determine coverage and claim adjudication. Common modifiers are listed in the provided input but are not discussed here in detail.

Readers will learn the clinical scope captured by the code, the typical settings where the procedure is performed, and how this code fits into surgical service lines for head and neck procedures. The publication provides benchmarks and policy-relevant context where available, explains documentation elements that affect coding and coverage, and outlines limitations when input data is missing. Data not available in the input includes specific associated taxonomies, ICD-10 diagnosis pairings, related codes, and payer-specific billing rules.

Billing Code Overview

CPT code 42104 describes a procedure in which a provider removes a lesion from the palate or uvula without performing any closure at the site. This represents an excisional procedure limited to superficial soft tissue of the oropharyngeal region.

Service type: Surgical excision of lesion, oropharynx (palate/uvula)
Typical site of service: Ambulatory surgical center or hospital outpatient department, and may also be performed in-office when clinical setting and patient factors permit

Clinical Context

A 52-year-old patient presents to an otolaryngology clinic with a symptomatic, well-circumscribed mucosal lesion on the soft palate causing discomfort and intermittent bleeding. After clinical evaluation and topical or local anesthetic administration, the surgeon removes the lesion using cold steel excision without flap creation or layered closure; no closure is performed and hemostasis is achieved with cautery. The procedure is performed in an outpatient ambulatory surgical center under local anesthesia with monitored anesthesia care; the specimen is sent for pathology. Typical workflow includes preoperative assessment, informed consent, lesion excision, hemostasis, specimen handling, brief observation, and discharge with wound-care instructions and pathology follow-up.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the physician’s professional services separate from a facility component (rare for minor outpatient excisions billed globally).
`50`	Bilateral procedure	Use when identical lesions on both sides of the palate/uvula are excised and insurance requires bilateral reporting.

Taxonomy Code	Specialty	Notes
`207Y00000X`	Otolaryngology (ENT)	Primary specialty performing oral and palatal lesion excisions.
`207L00000X`	Oral and Maxillofacial Surgery	Performs excisions for lesions involving deeper palatal tissues or when dental/occlusal issues intersect.
`2080P0003X`	Plastic Surgery	Involved when excision may affect esthetic or reconstructive considerations of the palate/uvula.
`207K00000X`	General Surgery	Occasionally performs or assists with intraoral lesion excisions in hospital settings.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`K13.2`	Benign neoplasm of other and unspecified oral mucosa	Common indication for excision of localized benign palatal lesions such as fibromas or papillomas.
`K13.9`	Disease of lip and oral mucosa, unspecified	General label for nonspecific oral mucosal disease that may prompt diagnostic excision.
`D23.9`	Benign neoplasm of skin, unspecified	Applied for mucocutaneous benign lesions of the soft palate when appropriate by payer guidance.
`C00.9`	Malignant neoplasm of lip, unspecified	Relevant when preoperative concern for malignancy exists; excision may be diagnostic and therapeutic.
`R22.9`	Localized swelling, mass and lump, unspecified	Used when presenting complaint is a palatal mass of uncertain etiology requiring excision for diagnosis.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`42105`	Excision of lesion of palate or uvula, with primary closure	Performed when the excised palatal lesion is closed primarily; use when closure is performed instead of open excision.
`40490`	Biopsy of oral mucosa (punch or incisional)	May be performed if only a limited diagnostic sample is taken rather than complete lesion excision.
`11102`	Tangential biopsy of skin (e.g., shave), single lesion	Used for superficial mucosal lesions in limited settings when a tangential technique is appropriate.
`88305`	Level IV surgical pathology, gross and microscopic examination	Typical pathology CPT for a tissue specimen submitted after excision of a palatal lesion.
`99024`	Postoperative follow-up visit, routine, during global period	Used by the surgeon for routine postoperative evaluation during the global period when separate billing is allowed.
