Questions About H50.69Overview

Is H50.69 (Mechanical strabismus) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other mechanical strabismus on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does H50.69 group to?

When other mechanical strabismus is the principal diagnosis on an inpatient stay, it groups to MS-DRG 124, 125, with relative weights from 0.7678 to 1.3231 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of H50.69?

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
