W21.09XA is a billable ICD-10 code used to specify a medical diagnosis of struck by other hit or thrown ball, initial encounter. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
W21.09XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like struck by other hit or thrown ball. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.
