CPT 42955: Pharyngostomy for Long-Term Enteral Feeding

CPT code 42955 represents a surgical pharyngostomy procedure to create an artificial opening in the pharynx for long-term enteral feeding. This procedure is clinically important for patients who cannot maintain adequate oral nutrition due to obstructive, neurologic, or structural disorders. Nationally, it is relevant to acute-care surgical services, nutrition support programs, and discharge planning for patients requiring prolonged enteral access.

Key payers in the scope of this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides an overview of clinical context, typical sites of service, and payer coverage considerations. Readers will find benchmarks for utilization and reimbursement patterns, policy updates affecting coverage and prior authorization practices, and clinical considerations that influence coding and care pathways.

The report also outlines common billing modifiers and how they interact with procedure reporting, operational considerations for hospitals and ambulatory surgical centers, and areas where policymakers and payers frequently set limits or criteria for coverage. Data not available in the input is noted explicitly where applicable.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with chronic dysphagia and risk of aspiration due to neurologic disease (for example advanced stroke, amyotrophic lateral sclerosis, or Parkinson disease) who requires long‑term enteral nutrition. The patient is evaluated by a multidisciplinary team (otolaryngology or general surgery, speech‑language pathology, nutrition, and nursing). After goals of care discussion and assessment that percutaneous or endoscopic gastrostomy is contraindicated or not feasible, the physician schedules a surgical pharyngostomy to create a durable opening in the pharynx for long‑term feeding access. The procedure is performed in an operating room under general anesthesia or monitored anesthesia care. Intraoperative steps include exposure of the pharyngeal wall, creation of a stoma, maturation of the opening to the skin, and placement of a feeding tube or stoma appliance. Postoperative workflow includes recovery room monitoring, confirmation of tube position and function, initiation of appropriate tube feeding protocols, wound care instructions, and outpatient follow‑up with the surgical team and nutrition services.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when work or complexity substantially exceeds typical for the procedure (document increased work).
`52`	Reduced services	Use when the procedure is partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when the procedure is started but terminated due to extenuating circumstances.
`62`	Two surgeons	Use when two surgeons from different specialties perform distinct portions of the procedure.
`63`	Procedure performed on infants less than 4 kg	Use when patient is an infant meeting weight criteria and special reporting is required.
`66`	Surgical team approach	Use when a surgical team performs portions of the care and billing reflects team participation.
`73`	Discontinued outpatient procedure prior to anesthesia or incision	Use when outpatient procedure is stopped after anesthesia is given but before incision.
`78`	Unplanned return to operating room by same physician following initial procedure	Use for related return to the OR for a postoperative complication on the same day or during global period.
`79`	(Not in provided list)	Data not available in the input.
`50`	Bilateral procedure	Use if a bilateral procedure code pairing is relevant (rare for pharyngostomy).

Taxonomy Code	Specialty	Notes
2080S00000X	General Surgery	General surgeons commonly perform open pharyngostomy procedures.
207ZP0006X	Otolaryngology (ENT)	ENT surgeons perform pharyngeal access procedures and stoma creation.
2086S0002X	Thoracic Surgery	Thoracic surgeons may be involved when airway or high pharyngeal access overlaps with thoracic procedures.
