Complication of inhalation therapy, sequela

This code signifies a long-term or residual effect stemming from a past complication of inhalation therapy. It indicates that the acute phase of the complication has resolved, but the patient continues to experience a lasting health issue directly attributable to that event. This could involve chronic respiratory problems, structural damage, or other persistent sequelae.

Use this code when documenting a patient presenting with a chronic condition or permanent impairment that is a direct consequence of a previous adverse event related to inhalation therapy. This applies when the original complication is no longer active but has left a lasting impact. Examples include chronic obstructive pulmonary disease (COPD) exacerbations due to prior ventilator-associated pneumonia, or persistent tracheal stenosis following prolonged intubation.

• Always sequence this code after the code identifying the specific nature of the sequela (e.g., J44.9 for COPD).
• Ensure documentation clearly links the current condition to a past complication of inhalation therapy.
• Do not use for acute complications; those require codes from the T81.81X_ category without the 'S' seventh character.
