Gastr contents in oth prt resp tract cause oth injury, sqla

This code indicates a long-term or residual health problem resulting from the aspiration of stomach contents into the respiratory tract, excluding the lungs, bronchi, or trachea. This aspiration event caused an injury to the affected respiratory structure, and the sequela refers to the lasting effects of that injury.

Use this code when documenting a patient presenting with a chronic condition or complication directly attributable to a past event of gastric content aspiration into respiratory areas such as the larynx, pharynx, or nasal passages. This applies when the initial acute injury has resolved, but its lasting impact is still being managed.

• Requires a seventh character "S" to indicate sequela, meaning the initial injury has passed and the code describes the residual effect.
• Always link this code to a definitive diagnosis of the specific sequela (e.g., chronic laryngitis due to aspiration).
• Do not use for acute aspiration events; those require codes from the T17.81 category without the "S" seventh character.
