What is the code F43.10?
F43.10 is a billable/specific ICD-10-CM code for "post-traumatic stress disorder, unspecified." This code falls under the chapter of Mental, Behavioral, and Neurodevelopmental Disorders (F01–F99) and, more specifically, under category F43, Reaction to severe stress and adjustment disorders. It is used in clinical settings to document a diagnosis of PTSD when the specific understanding is not designated.
Detailed description of F43.10
F43.10 covers cases where an individual exhibits symptoms of PTSD without further specification regarding the onset. It includes cases where the traumatic event leads to lasting psychological distress but does not specify the onset of PTSD as acute or chronic,

Appropriate usage of F43.10 for billing
F43.10 should be used for billing and diagnostic purposes when a provider lists that a patient presents with symptoms of PTSD in the assessment portion of their note, but the clinical documentation does not specify the acuity based on duration or onset of symptoms. F43.10 may also be assigned in cases where the provider has documented the diagnosis as "traumatic neurosis.”
When coding with F43.10, thorough documentation of the trauma and its psychological impact is beneficial but not required for physician reporting. Clinicians should note all symptoms affecting the patient and ensure these are consistent with a PTSD diagnosis even if the onset timing or specific features are not detailed.
