  1. Which ICD-10-CM code is used for respiratory failure as the primary reason for an emergency ambulance call?

    Answer: J96.00

    J96.00 represents acute respiratory failure, unspecified, which is used when the physician has documented respiratory failure as the condition requiring emergency transport.

  2. A patient is transported following a drug overdose. Which ICD-10-CM guideline applies to sequencing the poisoning code?

    Answer: Code the poisoning first, then the manifestation

    ICD-10-CM guidelines for poisoning require that the poisoning code (T36–T65) be sequenced first, followed by the manifestation codes.

  3. When coding a cardiac arrest transport, which ICD-10-CM code represents cardiac arrest due to underlying cardiac condition?

    Answer: I46.9

    I46.9 is used for cardiac arrest, cause unspecified, when documentation does not specify the underlying etiology.

  4. Which external cause code (V, W, X, Y) category is used to identify a motor vehicle accident as the cause of injury during an ambulance call?

    Answer: V codes

    V codes (V00–V99) in ICD-10-CM cover transport accidents, including motor vehicle collisions, and are used as external cause codes.

  5. A patient with COPD exacerbation is transported via ambulance. Which ICD-10-CM code best captures an acute exacerbation of COPD?

    Answer: J44.1

    J44.1 (COPD with acute exacerbation) is used when the patient with COPD is experiencing an acute worsening requiring emergency intervention.

  6. Which ICD-10-CM placeholder character 'X' is used for codes requiring a certain number of characters before the 7th character extension?

    Answer: X is used to fill empty character positions

    The placeholder 'X' fills character positions 4, 5, or 6 in ICD-10-CM codes that require a 7th character but have fewer than 6 characters in the base code.
