Radiographic dye allergy status

This code indicates that a patient has a documented history of an adverse reaction or allergy to radiographic contrast media (dyes). This status is important for preventing future allergic reactions during diagnostic imaging procedures that require contrast enhancement.

Apply this code when a patient's medical record clearly states a past allergic response to contrast dye, regardless of whether the reaction was mild or severe. It should be used to flag patients who require alternative imaging modalities or specific pre-medication protocols before contrast administration.

• Always confirm the specific type of contrast dye if documented (e.g., iodine-based, gadolinium-based) for more precise historical context, though this code is general.
• Do not use this code for current acute allergic reactions; those would be coded with specific allergy codes.
• This code is a "status" code, meaning it indicates a historical condition that impacts future care, not an active problem.
