ICD-10-CM H59.89
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

H59.89 is a billable ICD-10-CM diagnosis code for other postprocedural complications and disorders of eye and adnexa, not elsewhere classified. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 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 34 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative eye complication.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to H59.89: its own notes plus those printed at H59 and Chapter 7. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From H59 Intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified applies to 66 codes
  • mechanical complication of intraocular lens (T85.2)
  • mechanical complication of other ocular prosthetic devices, implants and grafts (T85.3)
  • pseudophakia (Z96.1)
  • secondary cataracts (H26.4-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)

Notes

General instructions on how these codes are used.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes

Questions About H59.89Overview

Is H59.89 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other postprocedural complications and disorders of eye and adnexa, not elsewhere classified on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does H59.89 group to?

When other postprocedural complications and disorders of eye and adnexa, not elsewhere classified is the principal diagnosis on an inpatient stay, it groups to MS-DRG 920, 919, 921, with relative weights from 0.6719 to 1.7624 depending on complications. Higher weights mean higher Medicare reimbursement.

Is H59.89 a CC or MCC?

CMS lists H59.89 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 34 closely related codes in its exclusion list.

Can H59.89 be reported with T85.2?

Not as a rule. The Excludes1 note at H59, which applies to H59.89, 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 H59.89?

Under the General Equivalence Mappings, other postprocedural complications and disorders of eye and adnexa, not elsewhere classified converts to ICD-9-CM 997.99 (surg compl-body syst NEC). The mapping is approximate, so confirm the match fits the documentation.
