About coding episcleritis
The ICD-10-CM code for episcleritis is H15.10 (Unspecified episcleritis). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H15.10.
Within H15.1, choose H15.10 (Unspecified episcleritis) only when documentation doesn't support a more specific option: periodica fugax (H15.11) and nodular episcleritis (H15.12).
To report this condition, pick the subcode that matches the documentation: H15.101 (right eye), H15.102 (left eye), H15.103 (bilateral) and H15.109 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
