H90 vs H91.1
H90 (Conductive and sensorineural hearing loss) compared with H91.1 (Presbycusis), from the official CMS tabular data.
Summary
No coding relationship between these codes was found in the tabular notes or in MedCoder’s derived relationships.
- What is different?
The conditions named.H90 is “Conductive and sensorineural hearing loss”; H91.1 is “Presbycusis”.
Registry fact
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other, and no derived relationship links them. Each may be reported when its own documentation requirements are met.
Registry fact
- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code. H90 carries 6 Excludes1 notes and H91.1 carries 6 Excludes1 notes covering other codes; the side-by-side table quotes them.
Official rule
- Is there an Excludes2 relationship?
None.Neither entry carries an Excludes2 note that names the other code.
Official rule
- Is one more specific?
Not comparable.The codes sit in different categories; specificity is only comparable within one category.
- Is one a parent or header code?
Both are headers.Both are non-billable headers, and neither contains the other.
Registry fact
- Are there sequencing instructions?
None.Neither entry carries a Code First or Use Additional Code note that names the other.
Official rule
- Are there other coding relationships?
None found.No laterality, encounter-phase, Table of Neoplasms, Table of Drugs and Chemicals, or history-versus-active-disease relationship links these codes.
MedCoder-derived
Official rule: a tabular instructional note or a section of the ICD-10-CM Official Guidelines, quoted as published. Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set). MedCoder-derived: a reading MedCoder computes from those facts; it is not itself a rule. How to read the labels
Can these codes be reported together?
Yes.
No Excludes1/Excludes2 relationship exists between these codes in the official tabular list. Each may be reported when its own documentation requirements are met.

Notes are the code’s own tabular entry, quoted as published. A note that names the other code is the one the verdict above rests on.
