The statement is true. The term "Excludes 2" shows that two seemingly related conditions can be billed in the same encounter. See Section I of the Coding Guidelines in the ICD-IO-CM 2020 edition for reference.

Durable medical equipment is represented by E codes, orthotic procedures are L codes, and enteral therapy is inclusive to B codes in the HCPC manual.

The left coronary artery and the right common carotid artery would each be considered their own vascular family. Therefore, when the starting point of selective catheterization is the aorta, the left coronary artery would be considered first order (36215) in the vascular family and the right common carotid artery would be considered the second order (36216). Modifier 59 is appended to indicate that a different vascular family was examined in one session. Contrast materials and catheterization into the aorta are inclusive to the nvo procedures and are not to be separately coded.

When coding a telehealth encounter for an outpatient practice that occurs over audio-video technology (e.g. Skype), the appropriate office visit E/M would be reported with modifier 95. The patient must initiate the telehealth encounter. Although similar, CPT code 99442 is billed when a patient initiates communication with a provider through an online patient portal. ICD-IO-CM Z20.828 is reported only when a patient does not exhibit any symptoms of a disease the patient is suspected to have been exposed to.

Observation hospital care is provided to patients who are not sick enough to be admitted.
Therefore, it is considered an outpatient service and is covered under Medicare part B.
