A15 vs A19.9

A15 (Respiratory tuberculosis) compared with A19.9 (Miliary tuberculosis, unspecified), 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 and billing status.A15 is “Respiratory tuberculosis”; A19.9 is “Miliary tuberculosis, unspecified”. A15 is a non-billable header; A19.9 is billable.

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. A15 carries 7 Excludes1 notes and A19.9 carries 7 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?

One is a header.A15 is a non-billable header, but A19.9 is not one of its subdivisions.

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.
