Coder workflow for I97
MedCoder structured workflow — derived from this code’s own official record
Before you code I97
- I97 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).
ReviewI97.0, I97.1, I97.2, I97.3, I97.4, I97.5, I97.6, I97.7, I97.8
See the relationships section · Guide: How to choose an ICD-10-CM code →
- “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on I97; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).
See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →
Choose the right path
- Does the documentation support one of the more specific codes beneath I97?
Yes → Select that code and continue the checks below on its own page.
No → I97 cannot be reported as written; query for the specificity its subcategory needs.ReviewI97.0, I97.1, I97.2, I97.3, I97.4, I97.5, I97.6, I97.7, I97.8
Consider I97. Then confirm the code is valid for the date of service in the Verify section.
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).
- Any detail beyond this code’s title
- What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.
Official instructions as workflow
Excludes2 — not part of I97(1 note)
Coding workflow: The conditions named in this note are not included in I97. 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.

Relationships & Classification
MedCoder structured relationships — computed from published CMS and AHRQ datasets
Other codes that name I97 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 10 Excludes2 notes: T80 — Complications following infusion, transfusion and therapeutic injection, T80-T88 — Complications of surgical and medical care, not elsewhere classified (T80-T88), T81 — Complications of procedures, not elsewhere classified, T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts, T83 — Complications of genitourinary prosthetic devices, implants and grafts, T84 — Complications of internal orthopedic prosthetic devices, implants and grafts, T85 — Complications of other internal prosthetic devices, implants and grafts, T86 — Complications of transplanted organs and tissue, T87 — Complications peculiar to reattachment and amputation, T88 — Other complications of surgical and medical care, not elsewhere classified.
These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

Common coding questions
Can I97 be billed directly?
No. I97 (Intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
