S11.22XA is a billable ICD-10-CM diagnosis code for laceration with foreign body of pharynx and cervical esophagus, initial encounter. The 7th character A marks it as an initial encounter code, used while the patient is receiving active treatment. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 11 through 13, 154 through 156, 963 through 965. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 39 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Open wounds of head and neck, initial encounter.
