L86 — Keratoderma in diseases classified elsewhere

Billable / specific codeICD-10-CM

L86 is a billable, specific ICD-10-CM code for keratoderma in diseases classified elsewhere. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

gonococcal keratoderma (A54.89)
gonococcal keratosis (A54.89)
keratoderma due to vitamin A deficiency (E50.8)
keratosis due to vitamin A deficiency (E50.8)
xeroderma due to vitamin A deficiency (E50.8)

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
Reiter's disease (M02.3-)

Risk adjustment

L86 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.

Medicare coverage

L86 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

A57954Billing and Coding: Routine Foot Care

How L86 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to L86.
