About coding pharynx congenital diverticulum
The ICD-10-CM code for pharynx congenital diverticulum is Q38.7 (Congenital pharyngeal pouch).
Within Q38 (other congenital malformations of tongue, mouth and pharynx), Q38.7 is specifically for congenital pharyngeal pouch. Related codes cover congenital malformations of lips, not elsewhere classified (Q38.0), Ankyloglossia (Q38.1), Macroglossia (Q38.2), other congenital malformations of tongue (Q38.3), congenital malformations of salivary glands and ducts (Q38.4), congenital malformations of palate, not elsewhere classified (Q38.5), other congenital malformations of mouth (Q38.6) and other congenital malformations of pharynx (Q38.8).
Don't report Q38.7 together with the conditions in its Excludes1 note: pharyngeal pouch syndrome (D82.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for Q38.7)
- pharyngeal pouch syndrome (D82.1)
