Other injury of heart, unspecified with or without hemopericardium, initial encounter

Version 2021

Valid for Submission

S26.99XA is a billable diagnosis code used to specify a medical diagnosis of other injury of heart, unspecified with or without hemopericardium, initial encounter. The code S26.99XA is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

S26.99XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like other injury of heart unspecified with or without hemopericardium. 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.

Unspecified diagnosis codes like S26.99XA are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
