Coder workflow for H93.21
MedCoder structured workflow — derived from this code’s own official record
Before you code H93.21
- H93.21 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).

Choose the right path
- Does the documentation support one of the more specific codes beneath H93.21?
Yes → Select that code and continue the checks below on its own page.
No → H93.21 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.
Report the code beneath H93.21 that the documentation supports, not H93.21 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).
Official instructions as workflow
Excludes2 — not part of H93.21(1 note)
Coding workflow: The conditions named in this note are not included in H93.21. 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.

Relationships & Classification
MedCoder-derived relationships — computed from published CMS and AHRQ datasets
Other codes that name H93.21 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.
Referenced by 2 Excludes1 notes: H90.5 — Unspecified sensorineural hearing loss (via H93.2.-), H91 — Other and unspecified hearing loss (via H93.2.-).
These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
Contextual Map
Every relationship of H93.21 in one view: hierarchy, official tabular instructions in both directions, clinical classification, risk adjustment, MS-DRG participation, index terms and change history — each edge carrying the CMS source it derives from.
