Inhalation of dry ice, sequela

This code describes the long-term or residual effects resulting from a past inhalation injury caused by dry ice. These sequelae can manifest as chronic respiratory issues, such as persistent cough, shortness of breath, or lung damage, that developed after the initial exposure. It indicates that the patient is no longer in the acute phase of the injury but is experiencing ongoing health problems attributable to it.

Use this code when documenting conditions that are a direct consequence of a previous dry ice inhalation incident, occurring after the acute phase of the injury has resolved. This applies to patients presenting with chronic respiratory symptoms or other lasting health complications definitively linked to the past exposure. It should be assigned when the patient is being treated for these residual effects, not the initial acute injury.

• Always sequence this sequela code after the code for the specific manifestation of the sequela (e.g., chronic bronchitis, pulmonary fibrosis).
• Ensure documentation clearly links the current condition to a past dry ice inhalation event.
• Do not use for acute dry ice inhalation; refer to codes for initial encounters.
