H59.222 is a billable ICD-10-CM diagnosis code for accidental puncture and laceration of left eye and adnexa during other procedure. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 791, 793, 919 through 921. 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 78 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative eye complication.

Questions About H59.222Overview

Is H59.222 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report accidental puncture and laceration of left eye and adnexa during other procedure on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does H59.222 group to?

When accidental puncture and laceration of left eye and adnexa during other procedure is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 920, 919, 921, with relative weights from 0.6719 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.

Is H59.222 a CC or MCC?

CMS lists H59.222 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 78 closely related codes in its exclusion list.

Can H59.222 be reported with T85.2?

Not as a rule. The Excludes1 note at H59, which applies to H59.222, lists "mechanical complication of intraocular lens (T85.2)". 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).

What is the ICD-9 equivalent of H59.222?

Under the General Equivalence Mappings, accidental puncture and laceration of left eye and adnexa during other procedure converts to ICD-9-CM 998.2 (accidental op laceration). The mapping is approximate, so confirm the match fits the documentation.
