Hip Injuries and Disorders
Your hip is the joint where your femur (thigh bone) meets your pelvis (hip bone). There are two main parts: a ball at the end of the femur, which fits in a socket in the pelvis. Your hip is known as a ball-and-socket joint. This is because you have a ball at the end of your femur, and it fits into a socket in your pelvis.

Questions About M91.0Overview
What is the ICD-10 code for juvenile osteochondrosis of pelvis?

Is M91.0 (Juvenile osteochondrosis of hip and pelvis) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report juvenile osteochondrosis of pelvis on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does M91.0 group to?
When juvenile osteochondrosis of pelvis is the principal diagnosis on an inpatient stay, it groups to MS-DRG 554, 553, with relative weights from 0.8328 to 1.2492 depending on complications. Higher weights mean higher Medicare reimbursement.
Can M91.0 be reported with a code from M93.0?
Not as a rule. The Excludes1 note at M91, which applies to M91.0, lists "slipped upper femoral epiphysis (nontraumatic) (M93.0-)". 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 M91.0?
Under the General Equivalence Mappings, juvenile osteochondrosis of pelvis converts to ICD-9-CM 732.1 (juv osteochondros pelvis). The mapping is approximate, so confirm the match fits the documentation.
