About coding paroxysmal hemicrania
The ICD-10-CM code for paroxysmal hemicrania is G44.039 (Episodic paroxysmal hemicrania, not intractable). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G44.039.
Within G44.03 (episodic paroxysmal hemicrania), G44.039 is specifically for episodic paroxysmal hemicrania, not intractable. Related codes cover intractable (G44.031).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 102 (Headaches with MCC, relative weight 1.1201) and DRG 103 (Headaches without MCC, relative weight 0.822), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
