H01.005 ICD-10-CM Code: Unspecified blepharitis left lower eyelid

H01.005 is the ICD-10-CM diagnosis code for unspecified blepharitis left lower eyelid. This code describes inflammation of the eyelid on the lower left eye, but the specific type or cause of the inflammation has not been identified or documented. The condition causes redness, irritation, and sometimes crusting or scaling of the eyelid. H01.005 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of eyelid, lacrimal system and orbit (h00-h05).

H01.005 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

Query the provider if the type of blepharitis (anterior, posterior, or unspecified) can be determined from clinical documentation, as more specific codes may be available.
