Coder workflow for F19

MedCoder structured workflow — derived from this code’s own official record

Before you code F19

  1. F19 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).

    ReviewF19.1, F19.2, F19.9

    See the relationships section · Guide: How to choose an ICD-10-CM code →

  2. “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on F19; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).

    See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →

Choose the right path

  1. Does the documentation support one of the more specific codes beneath F19?
    Yes → Select that code and continue the checks below on its own page.
    No → F19 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewF19.1, F19.2, F19.9

Consider F19. Then confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement
Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
Any detail beyond this code’s title
What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Code Overview

Other psychoactive substance related disorders is a non-billable ICD-10-CM category code (F19). A more specific billable subcode must be selected for claims submission.

Chapter 5: Mental, Behavioral and Neurodevelopmental disorders (F01 – F99)

1) In Remission Selection of codes describing “in remission” for categories F10-F19, Mental and behavioral disorders due to psychoactive substance use (categories F10-F19 with -.11, -.21, -.91) requires the provider’s clinical judgment and are assigned only on the basis of provider documentation (as defined in the Official Guidelines for Coding and Reporting), unless otherwise instructed by the classification.

Chapter 15: Pregnancy, Childbirth, and the Puerperium (O00-O9A)

3) Drug use during pregnancy, childbirth and the puerperium Codes under subcategory O99.32, Drug use complicating pregnancy, childbirth, and the puerperium, should be assigned for any pregnancy case when a patient uses drugs during the pregnancy or postpartum. This can involve illegal drugs, or inappropriate use or abuse of prescription drugs. Secondary code(s) from categories F11-F16 and F18-F19 should also be assigned to identify manifestations of the drug use.

Referenced by 2 Excludes1 notes: R41.3 — Other amnesia, R44 — Other symptoms and signs involving general sensations and perceptions.

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
