M99.05 - Segmental and somatic dysfunction of pelvic region

The ICD-10-CM code M99.05 denotes segmental and somatic dysfunction of the pelvic region, a condition affecting the musculoskeletal system and connective tissue. This diagnosis is pertinent when the pelvis is impaired or altered in function, potentially impacting mobility and causing discomfort.

In this context, segmental and somatic dysfunction means that, in the pelvic region, there is a localized misalignment or incorrect movement of the pelvis, and its functions are either impaired or altered. This type of pelvic region problem is usually caused by damage because of stresses, strains, and even trauma to the pelvic region. A postural abnormality in the region can also cause this.

Is the M99.05 billable?

Yes, M99.05 is a billable/specific ICD-10-CM code accepted for reimbursement purposes. It accurately represents diagnoses related to somatic dysfunction in the pelvic region.

Clinical information

Let's stipulate that you have a patient who set up an appointment to discuss a problem concerning their lower back. Have them expound on that and ask specifically what they feel. If they mention several of the following symptoms, then there might be a chance that they are dealing with the segmental and somatic dysfunction of their pelvic region:

Limited mobility or stiffness in the pelvis
Pain or discomfort in the lower back or abdomen
Muscle tension or spasms affecting the pelvic area
Numbness or tingling sensations
Swelling or a feeling of compression in the pelvic region

Diagnosis typically involves a thorough physical examination and may include imaging studies to assess the extent of dysfunction. Treatment options often encompass osteopathic manipulative therapy, physical therapy, and, when necessary, pharmacological interventions to alleviate symptoms.
