About coding Ophthalmoplegic migraine
The ICD-10-CM code for Ophthalmoplegic migraine is G43.B0 (Ophthalmoplegic migraine, not intractable). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G43.B0.
Within G43.B (Ophthalmoplegic migraine), G43.B0 is specifically for Ophthalmoplegic migraine, not intractable. Related codes cover intractable (G43.B1).
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
