Is B08.5 a billable ICD-10-CM code?

Yes. B08.5 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does B08.5 sit in the tabular list?

Certain infectious and parasitic diseases (A00-B99), in the block Viral infections characterized by skin and mucous membrane lesions (B00-B09).

What cannot be coded together with B08.5?

B08.5 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above B08.5 (B08) and apply to it just the same.

B08.5

B08.5 — Enteroviral vesicular pharyngitis

Billable / specific codeICD-10-CM

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Herpangina

Excludes1 inherited from the categories above B08.5

These are not written on B08.5, but they bind it: a note on a category applies to every code beneath it. Billing B08.5 with anything listed here is a denial.

Written on B08 — Other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified

vesicular stomatitis virus disease (A93.8)

Other codes that can never be billed with B08.5

These codes carry an Excludes1 note pointing at B08.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B08.5 alone.

J02.8Acute pharyngitis due to other specified organisms

Risk adjustment

B08.5 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.

How B08.5 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 B08.5.
