ICD-10-PCS Code For Nasopharynx: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group D90D includes procedures performed to irradiate tissues in the nasopharynx using beam radiation. These ICD-10-PCS codes are used for inpatient documentation when external beam radiation therapy is delivered to the nasopharyngeal region for cancer treatment or other therapeutic indications. Accurate coding within the ICD-10-PCS D90D group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Nasopharynx Beam Radiation Procedure Overview

This procedure group includes beam radiation treatments directed at the nasopharynx within the ear, nose, mouth and throat body system. Procedures involve delivering targeted external beam radiation to nasopharyngeal tissues to treat malignant or other radiotherapy-indicated conditions. Accurate ICD-10-PCS coding ensures inpatient records reflect the radiation therapy delivered and supports correct facility reimbursement and clinical documentation.

When to Use

Use codes from this group when a patient receives external beam radiation directed at the nasopharynx during an inpatient encounter. These codes apply when beam radiation is the operative radiation therapy procedure documented for treatment of nasopharyngeal disease.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
D90D0ZZ	Beam Radiation of Nasopharynx using Photons <1 MeV
D90D1ZZ	Beam Radiation of Nasopharynx using Photons 1 - 10 MeV
D90D2ZZ	Beam Radiation of Nasopharynx using Photons >10 MeV
D90D3Z0	Beam Radiation of Nasopharynx using Electrons, Intraoperative
D90D3ZZ	Beam Radiation of Nasopharynx using Electrons
D90D4ZZ	Beam Radiation of Nasopharynx using Heavy Particles (Protons,Ions)
D90D5ZZ	Beam Radiation of Nasopharynx using Neutrons
D90D6ZZ	Beam Radiation of Nasopharynx using Neutron Capture

Typical Clinical Scenarios

An adult patient with newly diagnosed, locally advanced nasopharyngeal carcinoma is admitted for inpatient initiation of external beam radiotherapy as part of a combined-modality treatment plan. Simulation and setup determine photon therapy at energies between 1–10 MeV is appropriate to achieve target coverage while sparing adjacent critical structures. Beam radiation using mid-energy photons is delivered during the inpatient encounter to begin definitive treatment. Typical codes: D90D1ZZ
An elderly patient presents with acute airway compromise from hemorrhagic progression of a recurrent nasopharyngeal tumor and is admitted for urgent symptom control. After multidisciplinary review and hemostatic measures, palliative high-energy photon external beam radiation is delivered during the admission to reduce tumor bulk and control bleeding. Treatment requires deeper tissue penetration, so photons >10 MeV are used for the inpatient beam radiation session. Typical codes: D90D2ZZ
A younger adult with a recurrent nasopharyngeal malignancy previously treated with conventional photons is admitted for re-irradiation using proton therapy to limit cumulative dose to surrounding normal tissues. The inpatient procedure documents delivery of external beam heavy particle radiation (protons) targeted to the nasopharynx to achieve more conformal dose distribution during re-treatment. This approach is selected to reduce expected toxicity compared with further photon therapy. Typical codes: D90D4ZZ
