Questions About F52.9Overview

Is F52.9 a billable code?

Can F52.9 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because unspecified sexual dysfunction not due to a substance or known physiological condition describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

What is the ICD-9 equivalent of F52.9?

Under the General Equivalence Mappings, unspecified sexual dysfunction not due to a substance or known physiological condition converts to ICD-9-CM 302.70 (psychosexual dysfunc NOS) and V41.7 (sexual function problem). 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.
