Medical Coding “Clarified” For Airway Compromise & Foreign Body – ER Visit 

By By Janine Mothershed

Airway Compromise & Foreign Body – ER Visit

Medical Specialty:  Emergency Room Reports

Description: The patient is a 17-year-old female who presents to the emergency room with foreign body and airway compromise and was taken to the operating room. She was intubated and fishbone.

HISTORY OF PRESENT ILLNESS: The patient is a 17-year-old female who presents to the emergency room with foreign body and airway compromise and was taken to the operating room. She was intubated and fishbone.

PAST MEDICAL HISTORY: Significant for diabetes, hypertension, asthma, cholecystectomy, and total hysterectomy and cataract.

ALLERGIES: No known drug allergies.

CURRENT MEDICATIONS: Prevacid, Humulin, Diprivan, Proventil, Unasyn, and Solu-Medrol.

FAMILY HISTORY: Noncontributory. 

SOCIAL HISTORY: Negative for illicit drugs, alcohol, and tobacco.

PHYSICAL EXAMINATION: Please see the hospital chart.

LABORATORY DATA: Please see the hospital chart.

HOSPITAL COURSE: The patient was taken to the operating room by Dr. X, who is covering for ENT, and noted that she had airway compromise and a rather large fishbone was noted and that was removed. The patient was intubated, and it was felt that she should be observed to see if the airway would improve, upon which she could be extubated. If not, she would require tracheostomy. The patient was treated with IV antibiotics and ventilatory support, and at the time of this dictation, she had recently been taken to the operating room, where it was felt that the airway was sufficient, and she was extubated. She was doing well with good p.o.s, good airway, good voice, and desiring to be discharged home. So, the patient is being prepared for discharge at this point. We will have Dr. X evaluate her before she leaves to make sure I do not have any problem with her going home. Dr. Y feels she could be discharged today and will have her return to see him in a week. 

Key Documentation Findings

First, review what the record documents. The patient had a foreign body (a fishbone) in the airway, which caused airway compromise. The surgeon removed it in the OR. In addition, the patient required intubation with ventilatory support and received IV antibiotics. After observation and a successful extubation, the patient went home.

ICD-10-CM Diagnosis Coding

Primary Diagnosis

The primary diagnosis is a foreign body in the respiratory tract.

T17.298A Other foreign object in other part of respiratory tract, initial encounter

Additional Diagnoses (as Supported)

J98.8 Other specified respiratory disorders, for airway compromise if nothing more specific applies.

However, do not code symptoms such as airway compromise when the foreign body fully explains them. For this reason, you may omit this code depending on payer preference.

CPT Procedure Coding

Primary Procedure

31635 Bronchoscopy, rigid or flexible, with removal of foreign body

The rationale is simple. The surgeon removed the fishbone from the airway in the OR, and the removal required an endoscopic approach. Therefore, the bronchoscopy code is appropriate.

Airway Management

31500 Intubation, endotracheal, emergency procedure

Use this code only if the record documents the intubation separately and it is not bundled into the primary procedure.

HCPCS Coding

Medications and Supplies (If Billed Separately in an Outpatient or Facility Setting)

The patient received IV antibiotics. However, the record does not name the specific antibiotic, so you cannot assign an exact J code. Also, A4216 (sterile water or saline) may apply if the facility used it for IV administration.

Keep in mind that HCPCS drug coding depends on the specific drug name, the dosage, and the route.

What Not to Code

Do not code the extubation separately, because it is bundled into care. Likewise, do not code observation unless the setting makes it separately billable. Finally, do not code negative social history findings.

Final Code Summary

ICD-10-CM

  • T17.298A: Foreign body in respiratory tract
  • J98.8: Airway compromise (optional, if supported and not redundant)

CPT

  • 31635: Bronchoscopy with foreign body removal
  • 31500: Emergency intubation (if separately reportable)

HCPCS

  • J code for the IV antibiotic (drug not specified)
  • A4216 (if applicable)

CPC Exam Tip

Always code from the body of the operative report, not just the summary. In this case, the key phrase is “large fishbone… removed in the operating room.” That phrase drives your primary CPT code.
