ICD-10-CM Codes›H00–H59›H00-H05›H05
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
H05.023 is a billable ICD-10-CM diagnosis code for osteomyelitis of bilateral orbits. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 121 through 122. 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 225 closely related codes. Coders also document this condition as bilateral orbital osteomyelitis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Oculofacial plastics and orbital conditions and Osteomyelitis.

Bone Infections
Like other parts of the body, bones can get infected. The infections are usually bacterial, but can also be fungal. They may spread to the bone from nearby skin or muscles, or from another part of the body through the bloodstream.

Questions About H05.023Overview
What is the ICD-10 code for osteomyelitis of bilateral orbits?
The ICD-10-CM code for osteomyelitis of bilateral orbits is H05.023 (sometimes written as H05023). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is H05.023 (Osteomyelitis of orbit) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report osteomyelitis of bilateral orbits on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does H05.023 group to?
When osteomyelitis of bilateral orbits is the principal diagnosis on an inpatient stay, it groups to MS-DRG 122, 121, with relative weights from 0.7403 to 1.2249 depending on complications. Higher weights mean higher Medicare reimbursement.
Is H05.023 a CC or MCC?
CMS lists H05.023 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 225 closely related codes in its exclusion list.
Can H05.023 be reported with Q10.7?
Not as a rule. The Excludes1 note at H05, which applies to H05.023, lists "congenital malformation of orbit (Q10.7)". 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).
