Clinical InformationClinical

  • Muscle Rigidity

    continuous involuntary sustained muscle contraction which is often a manifestation of basal ganglia diseases. when an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. this feature helps to distinguish rigidity from muscle spasticity. (from adams et al., principles of neurology, 6th ed, p73)

Questions About R29.3Overview

Is R29.3 a billable code?

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

Can R29.3 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the abnormal posture is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R29.3?

Under the General Equivalence Mappings, abnormal posture converts to ICD-9-CM 781.92 (abnormal posture). The mapping is a direct match.

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.
