Questions About O62.2Overview

Is O62.2 (Abnormalities of forces of labor) a billable code?

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

What MS-DRG does O62.2 group to?

When other uterine inertia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 817, 818, 819, 831, 832, 833, with relative weights from 0.5229 to 1.6880 depending on complications. Higher weights mean higher Medicare reimbursement.

The Medicare Code Editor checks other uterine inertia against patient demographics: this code is intended for maternity cases (age 9 through 64). Claims outside these limits are flagged as inconsistent.

What is the ICD-9 equivalent of O62.2?

Under the General Equivalence Mappings, other uterine inertia converts to ICD-9-CM 661.21 (uterine inert NEC-deliv). The mapping is approximate, so confirm the match fits the documentation.

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.
