ICD-10-PCS Code For Tongue Palate Pharynx Muscle: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0KT4 includes procedures performed to resect muscles in the tongue, palate, and pharynx. These ICD-10-PCS codes are used for inpatient documentation when a complete muscle resection of the tongue, palate, or pharynx is performed to treat pathology such as tumor, severe dysfunction, or traumatic injury. Accurate coding within the ICD-10-PCS 0KT4 group is essential for proper inpatient reimbursement, as it captures the specific resection performed and determines appropriate case mix and payment.

Tongue Palate Pharynx Muscle Resection Procedure Overview

This procedure group includes resections of muscles of the tongue, palate, and pharynx and targets the muscular body system of the upper aerodigestive tract. Procedures involve cutting out or off, without replacement, all of a specified muscle or muscular portion to treat disease or dysfunction. Accurate ICD-10-PCS coding of these resections ensures inpatient documentation reflects the invasive muscular procedure performed and supports correct case mix assignment and reimbursement.

When to Use

Use a code from this group when the operative intent and documentation indicate complete resection of a tongue, palate, or pharynx muscle without replacement. These codes apply when the procedure removes the entire muscle for indications such as neoplasm, irreparable damage, or severe functional impairment.

Typical Clinical Scenarios

Adult patient presents emergently after a penetrating or avulsive oropharyngeal injury with devitalized muscle tissue of the tongue and floor of mouth; airway compromise and uncontrolled bleeding necessitate inpatient operative management to remove all nonviable tongue muscle tissue to control hemorrhage and reduce infection risk. Typical codes: 0KT40ZZ
Middle‑aged patient with a biopsy‑proven primary malignant tumor originating in the palatal musculature with planned inpatient surgical management; complete resection of the involved palatal muscle is performed electively to achieve oncologic margins and prepare for staged reconstruction or adjuvant therapy. Typical codes: 0KT44ZZ, 0KT40ZZ
Patient with progressive obstructive sleep apnea refractory to conservative therapy due to hypertrophic pharyngeal musculature and prior unsuccessful soft‑tissue procedures, now undergoing definitive inpatient resection of the affected pharyngeal muscle to remove the entire diseased muscle segment and relieve airway obstruction. Typical codes: 0KT44ZZ
