Operation Definition
Putting in or on a therapeutic, diagnostic, nutritional, physiological, or prophylactic substance except blood or blood products
Procedure Overview
Introduction covers putting a therapeutic, diagnostic, nutritional, physiological, or prophylactic substance into or onto a body region, other than blood or blood products, which fall under Transfusion instead. This wide-ranging family includes things like injecting anesthesia, infusing chemotherapy, instilling contrast for imaging, delivering anti-infective medications, or providing nutritional formula through a feeding route.
Because it spans so many substance types and delivery sites, this is one of the most frequently used families in the Administration section. A patient might encounter it during an epidural injection, a course of intravenous antibiotics, contrast dye given before a CT scan, or tube feeding after surgery; each represents a substance being placed into the body to achieve a specific therapeutic or diagnostic goal rather than a physical alteration of tissue.
Anatomy & Axis Detail
Respiratory Tract
Introduction into the respiratory tract refers to substances delivered into the trachea or bronchi beyond the nose and pharynx, such as nebulized bronchodilators, mucolytics, or surfactant instilled through an endotracheal tube, targeting the airway lining that governs gas exchange and mucociliary clearance. Because the lower airway is a continuous branching structure with no natural stopping point, documentation typically specifies whether delivery reached the trachea, mainstem bronchi, or was distributed more broadly, and whether an artificial airway was used as the access route. This differs from introduction into the nose or mouth and pharynx, which cover more proximal structures, and from irrigation, which removes rather than instills, so coders should confirm the substance's therapeutic intent and its endpoint within the tracheobronchial tree.
Approach: Via Natural or Artificial Opening
Via Natural or Artificial Opening in Administration covers substances introduced through an existing body orifice or stoma, such as an oral medication swallowed, a rectal suppository, or a drug instilled through a gastrostomy tube, without endoscopic guidance. It is distinguished from the Endoscopic variant by the lack of a scope, and from Percutaneous by using a natural passage rather than a puncture.
Substance: Gas
Gas covers administration of a gaseous substance, such as therapeutic oxygen or nitric oxide, given for its physiologic or therapeutic effect rather than as a liquid or solid preparation. It is distinguished from other Administration device values by its physical state, and is used specifically when the substance delivered to the patient is in gaseous rather than fluid or particulate form.
Qualifier: Nitric Oxide
Identifies nitric oxide gas as the substance administered, most often by inhalation to selectively dilate pulmonary blood vessels in conditions like persistent pulmonary hypertension of the newborn or acute respiratory failure. It has its own qualifier separate from Other Gas because of its specific, well-established therapeutic mechanism and narrow dosing requirements.
Coding & Documentation
Correct code assignment depends on identifying three things from the documentation: the substance given, matched to the correct qualifier value; the specific body region or route receiving it; and the approach used, such as percutaneous injection or an existing catheter. Physician orders and medication administration records are the primary support. The most common errors involve selecting an imprecise substance qualifier, for example coding a general anti-infective when the documentation specifies a particular drug category with its own value, or misidentifying the body region when a substance is delivered systemically versus locally, such as an intra-articular injection versus an intravenous one.
Commonly Confused With
This family is easily confused with Transfusion, but any blood or blood product is excluded here and must be coded under Transfusion instead, regardless of how it is delivered. It is also confused with routine medication administration that some facilities do not code separately when it is considered standard nursing care rather than a notable procedural event; coders should apply their facility's guidelines to determine which introductions rise to the level of a codable procedure.
