Postproc hematoma of unsp and adnexa fol an opth procedure

This code signifies the presence of a hematoma (a localized collection of blood outside of blood vessels) that develops in or around the eye after an ophthalmic surgical or diagnostic procedure. This condition indicates a complication directly related to the intervention, affecting an unspecified eye.

Apply this code when documentation clearly indicates a postprocedural hematoma of the eye or adnexa, without specifying laterality, following any ophthalmic procedure. This diagnosis requires a causal link between the procedure and the hematoma.

• Ensure the documentation explicitly states the hematoma is a postprocedural complication.
• If laterality (right or left eye) is specified, use the more specific codes H59.331 or H59.332.
• Code the underlying ophthalmic procedure that led to the hematoma as the primary diagnosis if it is the reason for the encounter, with this code as a secondary diagnosis.
