Is B30.3 a billable ICD-10-CM code?

Yes. B30.3 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does B30.3 sit in the tabular list?

Certain infectious and parasitic diseases (A00-B99), in the block Other viral diseases (B25-B34).

What cannot be coded together with B30.3?

B30.3 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 B30.3 (B30) and apply to it just the same.

Inclusion terms

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

Conjunctivitis due to coxsackievirus 24
Conjunctivitis due to enterovirus 70
Hemorrhagic conjunctivitis (acute)(epidemic)

Excludes1 inherited from the categories above B30.3

These are not written on B30.3, but they bind it: a note on a category applies to every code beneath it. Billing B30.3 with anything listed here is a denial.

Written on B30 — Viral conjunctivitis

herpesviral [herpes simplex] ocular disease (B00.5)
ocular zoster (B02.3)

Other codes that can never be billed with B30.3

These codes carry an Excludes1 note pointing at B30.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B30.3 alone.

H10.23Serous conjunctivitis, except viral

Risk adjustment

B30.3 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 B30.3 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 B30.3.
