Coder workflow for G47
MedCoder structured workflow — derived from this code’s own official record
Before you code G47
- G47 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).
ReviewG47.0, G47.1, G47.2, G47.3, G47.4, G47.5, G47.6, G47.8, G47.9

Choose the right path
- Does the documentation support one of the more specific codes beneath G47?
Yes → Select that code and continue the checks below on its own page.
No → G47 cannot be reported as written. Where the codes beneath it include an unspecified code, that code applies when the record goes no further; otherwise query for the missing detail.ReviewG47.0, G47.1, G47.2, G47.3, G47.4, G47.5, G47.6, G47.8, G47.9
Report the code beneath G47 that the documentation supports, not G47 itself. Then confirm that code is valid for the date of service on its own page.
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).

Excludes2 — not part of G47(4 notes)
Coding workflow: The conditions named in this note are not included in G47. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

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.
Coding context
Guidelines, coding notes, decision aids, relationships (with MS-DRG and CCSR classification), hierarchy, HCC, coverage and the context map: what a coder reaches for after the core. Each section names whether it is official source data, a MedCoder-derived relationship or MedCoder editorial.

Can G47 be billed directly?
No. G47 (Sleep disorders) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
