Non-billable headerICD-10-CM

L28 is a non-billable header ICD-10-CM code for lichen simplex chronicus and prurigo. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with L28

These codes carry an Excludes1 note pointing at L28. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L28 alone.

Risk adjustment

L28 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead L28

3 child codes. Green means billable.
