The ICD-10-CM code for purulent endophthalmitis is H44.00 (Unspecified purulent endophthalmitis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H44.00.

To report this condition, pick the subcode that matches the documentation: H44.001 (right eye), H44.002 (left eye), H44.003 (bilateral) and H44.009 (unspecified eye).
