- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
A48.52 is a billable ICD-10-CM diagnosis code for wound botulism. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 867 through 869. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 7 closely related codes. Coders also document this condition as infection caused by Clostridium botulinum. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Bacterial infections.

Questions About A48.52Overview
What is the ICD-10 code for wound botulism?
The ICD-10-CM code for wound botulism is A48.52 (sometimes written as A4852). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is A48.52 (Other specified botulism) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report wound botulism on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does A48.52 group to?
When wound botulism is the principal diagnosis on an inpatient stay, it groups to MS-DRG 867, 869, 868, with relative weights from 0.6784 to 2.1855 depending on complications. Higher weights mean higher Medicare reimbursement.
Is A48.52 a CC or MCC?
CMS lists A48.52 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 7 closely related codes in its exclusion list.
Can A48.52 be reported with A05.1?
Not as a rule. The Excludes1 note at A48.5, which applies to A48.52, lists "food poisoning due to toxins of Clostridium botulinum (A05.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
