M80.839A vs M80.839D
M80.839A (Other osteoporosis with current pathological fracture, unspecified forearm, initial encounter for fracture) compared with M80.839D (Other osteoporosis with current pathological fracture, unspecified forearm, subsequent encounter for fracture with routine healing), from the official CMS tabular data.
Summary
No tabular note links these codes. Both belong to category M80, and nothing in the tabular list prevents reporting each when it is documented.
Registry fact- What is different?
Title wording.The titles share “Other osteoporosis with current pathological fracture, unspecified forearm”; M80.839A says “initial encounter for fracture” where M80.839D says “subsequent encounter for fracture with routine healing”.
Registry fact
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other. Both belong to category M80; each may be reported when its own documentation is present.
Registry fact
- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code. M80.839A carries 3 Excludes1 notes and M80.839D carries 3 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. M80.839A carries 1 Excludes2 note and M80.839D carries 1 Excludes2 note covering other codes; the side-by-side table quotes them.
Official rule
- Is one more specific?
No.Both titles are unspecified forms within category M80, and neither is a subdivision of the other.
Registry fact
- Is one a parent or header code?
No.Both are billable codes, 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, when each is documented. M80.839A and M80.839D both belong to category M80.
No Excludes1/Excludes2 relationship exists between these codes in the official tabular list. The code titles state what each one covers, and the documentation decides which applies.

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.
