Surgical Diagnoses That Need Extra Detail in ICD-10-CM
These codes used to be one broad code each. Now they ask for side, site or type, and the code you pick depends on what the provider writes.
In this article
Some diagnosis codes that surgeons use all the time were once a single code with no detail. They have since been split by side, site or type. A code without that detail is either invalid (it isn't billable) or an "unspecified" code that invites a query. Each section below shows what to look for in the note.
Part 1 of 5
Pathological fracture of the pelvis: M80.0B- and M80.8B-
A pathological fracture happens in bone already weakened by disease, so it breaks with little or no injury. The osteoporosis codes for a fracture of the pelvis now carry the side and need a 7th character.
| Code | Meaning |
|---|---|
| M80.0B1- / M80.0B2- / M80.0B9- | Age-related osteoporosis with current pathological fracture, right / left / unspecified pelvis |
| M80.8B1- / M80.8B2- / M80.8B9- | Other osteoporosis (for example, drug-induced) with current pathological fracture, right / left / unspecified pelvis |
The 7th character is the same set used for other fractures:
| 7th character | Encounter |
|---|---|
| A | Initial encounter for the fracture |
| D | Subsequent encounter, routine healing |
| G | Subsequent encounter, delayed healing |
| K | Subsequent encounter, nonunion |
| P | Subsequent encounter, malunion |
| S | Sequela |
Example: an 80-year-old with age-related osteoporosis has a fracture of the left pelvis after stepping off a curb, and is seen for active treatment: M80.0B2A.
Part 2 of 5
Sepsis after a procedure: T81.44X-
When sepsis is a complication of a procedure, report T81.44X- (sepsis following a procedure) with the 7th character for the encounter (A, D or S), then a code for the infection's organism if known. A bloodstream infection caused by a central venous catheter has its own code: T80.211-.
Organism codes still matter. For example, A41.54 is sepsis due to Acinetobacter baumannii.
Part 3 of 5
Parkinson's disease: G20 is no longer billable
G20 is now a category, not a code. Pick one of these, based on whether the patient has dyskinesia (involuntary movements) and fluctuations (the medicine wearing off between doses):
| Code | Parkinson's disease |
|---|---|
| G20.A1 | Without dyskinesia, without mention of fluctuations |
| G20.A2 | Without dyskinesia, with fluctuations |
| G20.B1 | With dyskinesia, without mention of fluctuations |
| G20.B2 | With dyskinesia, with fluctuations |
| G20.C | Parkinsonism, unspecified |
A surgeon placing a feeding tube for a Parkinson's patient may not record these details, even though the neurologist knows them. Code from the documentation for the encounter you're coding; if it doesn't say, query the surgeon rather than picking G20.C.

Desmoid tumor by site: D48.110–D48.119
A desmoid tumor grows from connective tissue. It doesn't spread like a cancer, but it can grow into nearby tissue, most often the abdominal wall, shoulder or thigh. It used to be coded to D48.1; it now has its own codes by site.
| Code | Desmoid tumor of |
|---|---|
| D48.110 | Head and neck |
| D48.111 | Chest wall |
| D48.112 | Inside the chest (intrathoracic) |
| D48.113 | Abdominal wall |
| D48.114 | Inside the abdomen (intra-abdominal) |
| D48.115 | Upper limb and shoulder girdle |
| D48.116 | Lower limb and pelvic girdle |
| D48.117 | Back |
| D48.118 | Other site |
| D48.119 | Unspecified site |
Part 5 of 5
Family history of colon polyps: Z83.710–Z83.719
A family history of colon polyps can justify a colonoscopy sooner or more often than the usual screening schedule. The code now says what kind of polyp the relative had:
| Code | Family history of |
|---|---|
| Z83.710 | Adenomatous and serrated polyps |
| Z83.711 | Hyperplastic colon polyps |
| Z83.718 | Other colon polyps |
| Z83.719 | Colon polyps, unspecified |
